OUTBUILDINGS

WALL AT 52Brick:Is one course thick - apparently was in English bond. Size is 8¾" x 4¼" x 2½".
Mortar:Of oyster shell lime with shell aggregate. Surfaces of brick show traces of it.
Probable Use:Although fragmentary, the fact that this brickwork represents a corner indicates the possible direction the rest of the plan may have taken. It is the same type of brickwork as Chimney Foundation 64 and probably is what is left of the walls of the frame structure which surrounded the chimney. If so, the structure was approximately 36' x 20', using the double fireplace chimney as a center point.
Note that this brickwork in 52, Chimney 64, is same size as wall at 36. See general considerations. Also note that the brick has all appearances of being early as compared with other brickwork on the site.
Condition:Too fragmentary for re-use.
CHIMNEY AT 64Brick:As at wall 52 laid in English bond. Solid masonry in general three courses deep. No signs of adjoining walls. The South arm seems to have been broken off.
Mortar:As at wall 52.
Probable Use:As foundations for a chimney with two fireplaces. The Northern 1/3 of the original shape exists - with a portion of the wall dividing the two fireplaces which is broken at its Southern end.
Condition:Could be re-used.
4
GUTTER 53,54,55Brick:Size 9"-9¼" x 4¼" x 2½". Gutter floor laid in a pattern one brick thick with bricks on edge to form the sides. See section "K. K."
Mortar:No mortar joints. Gutter laid on a thin fill of broken brick and marl.
Probable Use:As a gutter leading away from the well. Note gradually descending gradient from the well 56 Northwards. Although the area was carefully tested, no further traces could be found of the gutter or information uncovered which would indicate the method of disposing of the water. The gutter fragments would seem to indicate that it turned Westwards at 54. Note that on the Russell site a gutter was employed to drain away from the well.
Condition:Too fragmentary for re-use.
WELL 56Brick:Has stone coping to depth of 2'-6". Stones crudely shaped and much worn. Stone seems to be Portland or Bath stone. Below the well is built of brick. Measurements of the bricks were not taken.
Mortar:Stone laid in a bed of mortar but with little or none in the joints.
Probable Use:As a well. The Southeast portion shows marks of continued use and stone curb has long fluted marks presumably made by contact with bucket ropes for years. This would indicate a hand operated well without pulleys or drum and crank and throws light on what type of covering may have been employed originally. Mortar joints on the top of the stone would indicate that the stonework originally extended up higher.
Condition:Fit for re-use with repairs. At the time of writing, this well was excavated to a depth of seven feet only. It is filled with debris of soil and broken brick, etc.
5
WALL AT 63Brick:Size is 8¾" - 9 x 4" x 2½" - one course deep in English bond.
Mortar:Slight traces of mortar probably oyster shell lime type.
Probable Use:As foundation of a wall for some kind of structure. See under General Considerations. It is too fragmentary for very definite assumptions.
Condition:Too fragmentary for re-use.
WALL AT 57Brick:Is so broken as to preclude measurement. Seems to have been laid on the paving at 58. Wall has slipped to West and was 9" thick. It is two courses deep.
Mortar:Oyster shell lime type, badly rotted.
Probable Use:This wall is so fragmentary and broken that it is hard to ascribe its original purpose. It does follow line of paving joints. It may have been part of a well house.
Condition:Very bad.
PAVING 58,59-62-61Brick:Seems to average about 8¾" x 4¼" x 2½". Paving is one brick deep laid with sanded joints on a thin bed of broken brick and marl. In general it is made of ½ and ¾ brick - batts rather than whole brick. It seems to have extended up and to the round foundation at 60. It was not possible to determine the original southern limits of it.
Mortar:None - see "Brick".
Probable Use:It is too fragmentary to ascertain what were the original limits. This makes it difficult to tell what purpose the paving may have served. The condition of this paving is too good to have been exposed to the weather. It would seem more probable that it was enclosed originally by some kind of structure which kept it well preserved.
Condition:Not good enough for re-use.
6
CIRCULAR WALL at 60Brick:Brick size 9 x 4¼" x 2½". Present top course is of stretchers indicating wall was in English bond. Below this present top course are two courses of brick laid in casual manner. The wall is badly broken and fragmentary.
Mortar:Oyster shell lime type.
Probable Use:Its shape and proximity to the well seem to indicate its use as a cool storage space - possibly as a dairy. See further discussion under General Considerations.
Condition:Not possible to re-use.
GUTTER 49-50Brick:Size 8½" x 4" x 2½". For form of gutter see section "J. J." Gutter slopes toward West. Most of the brick used are batts - with some mixed sizes.
Mortar:Bricks laid without mortar.
Probable Use:As a gutter and probably of a late period, since it is so close to the present grade, whereas original grade was below this level. Its position would tend to relate it in some way to the structure 51-45-47. If so, this would be an added reason for supposing the structure as being late as well.
FOUNDATION 51-48-45Brick:In wall 51-48, brick is 9" x 4¼" x 2½" but almost no whole brick appears as work is built up of batts (½ and ¾ brick). Bond is a cross between English and Common. Wall is 11 courses deep and butts chimney at 48.
In chimney at 47-48 brick size is 9"x4" x 2½". Brick are laid in a common bond modified by English. Brick are different in color than in the wall. Chimney brick extends under wall at 48. See elevation "L. L." showing relation of chimney to wall 51-48.
In wall 45-48, brick is 9" x 4¼" x 2½" and one course deep. Where it passes over chimney one-half of wall width is missing. Appears to have been laid in English bond.
7
FOUNDATION 51-48-45Mortar:All brick laid up in oyster shell lime mortar with a heavy aggregate of broken shells.
Probable Use:Three periods involved:
1. Is the chimney.
2. Is the South portion of the wall.
3. Is the North portion.
Periods 2 and 3 overlap the chimney which projects under and beyond the wall and is a different size and type of brick, indicating the chimney as earliest period. Wall 45-48 is of whole brick in English bond and falls into period 2 because wall 51-48 is of batts or re-used brick which puts it in the latest period.
North of the chimney and West of the wall the ground was full of fill to the bottom of the foundations. This fill contained early iron, china, glass, pottery, etc. fragments. Note this fill does not occur South of the chimney.
As the chimney is of period 1, the walls may or may not have had anything to do with the position and plan of the original structure. Even the chimney may have been, after all, more contemporaneous and less earlier than the walls, as assumed. Various possibilities may be listed, therefore:
1. That the chimney served a structure whose outer walls are now gone.
2. That it was part of a structure which wall 45-48 was part of.
3. That assumption 2 represents a structure to which a later addition was made Northward. Note remarks on gutter 49-51 above.
Condition:Chimney in part is in re-usable condition but rest of brickwork is not.
8
BRICK AT 44Brick:Same type as in chimney at 47.
Mortar:Same type as in chimney at 47.
Probable Use:Possibly as related to foundation 51-48-45 in some way.
PAVING 67-61Brick:Broken brick of mixed sizes laid flat in random pattern on thin layer of brick rubble and marl. At North end paving made mostly of marl.
Mortar:None.
Probable Use:Grades of this paving are higher than those of adjacent pavement at 62 indicating no relation between the two. The direction of this paving is roughly from a possible kitchen entrance to a rear entrance of the main house.
Condition:Not fit for re-use.
LINE OF POSTS 51-66About 2½ feet below the present grade were found the bottom ends of much rotted cedar posts as shown on the drawing. The line is definite and continues the line of the gutter at 49-51. Note also the late area of brick rubble and marl which overlaid the foundations of the kitchen and wash-house chimney terminates on this level line extended at 66-65.
Since this area of rubble surface is much later than the kitchen chimney and wall 68 and 69, it is reasonable to suppose the fence as more or less of the same period. The assumed reconstruction of chimney and wall 64 and 52 would interrupt the fence line also. It seems safe to assume that this fence is of a late period.
CHIMNEY 69Brick:Well laid in English bond. Size 9" x 4¼" x 2½". See sections "H. H." and "I. I." Note how the breast walls of the Northern chimney portion start to corbel inwards. No explanation seems apparent for this at the time of writing and comparative research suggests itself as a means to answer the question. Just South of the foundation are what appear to be fragments of
9
hearth because they are laid on sand in turn resting on from two to three courses of rough brickwork laid in mortar. The hearth brick are laid in mortar with finished surfaces which were ground or appear so from use.
In general, the bottom courses project as footings. Brickwork is of good quality.
Mortar:Is of oyster shell lime with heavy shell aggregate. Mortar is tough and hard.
Probable Use:As a chimney with two fireplaces. Near the chimney at West is a fragment of wall at 68. This is the same type brickwork as the chimney. The insurance policies indicate a kitchen in this location 32 x 20 feet. If the center of the chimney is considered the center line of the building, wall 68 is approximately 10 feet from it and if repeated to the East would give a width of 20 to 21 feet. The inventories refer to a building as "kitchen and wash house", which would answer for the two fireplaces. The insurance plats indicate a building not only at this position, but also with its longer dimension similarly placed. Note that a building on chimney 64 and wall 52 would be about the same size.
Condition:Fit for re-use if necessary, as far as it goes.
10
WALL AT 68Brick:Same as chimney 69. One course deep. The wall is made up of ½ and ¾ brick.
Mortar:Identical to chimney 69.
Probable Use:As described under chimney 69. Although the wall is made of ½ and ¾ brick, other considerations relate it to chimney 69. Ordinarily brickwork made of batts would indicate a late period, but since there is only one course of brick, the evidence is not extensive enough to so define it.
Condition:Too fragmentary for re-use.
RUBBLE AREA 66-65-68-70See foregoing remarks about this rubble area.
The rubble is composed of brick fragments, oyster shells, marl and general debris and gives the appearance of having been an old yard surface, but not of the 18th century period because it overlays the foundations at 68 and 69 which were part of the kitchen in existence in the early 19th century.
WALL AT 36Brick:Size 8¾" x 4¼" x 2½" laid in English bond two courses deep.
Mortar:Tough oyster shell lime mortar with heavy shell aggregate.
Probable Use:Insurance policies indicate South of kitchen with spaces of two feet between two out-buildings - a dairy nearest the kitchen and South of it a smoke house. The wall in question, then, could well be the North wall of the dairy. Note the similarity between this brickwork and that at 52 and 64.
Condition:Too fragmentary for re-use.
11
BRICK AT 37Brick:Size 8½" x 4" x 2¾" laid in English bond two courses thick. It is a corner of a wall and closers are used.
Mortar:Oyster shell lime type with light aggregate of shell and considerable yellow sand.
Probable Use:As the corner of a wall or pier. See explanation about wall at 36. Corner 37 is not related to it, apparently, being different brick and mortar. It would seem to be much later than wall 36 as the latter represented a 12 x 12 foot dairy. If it were related, it might be explained as a support for floor framing or for some interior feature since a 12 x 12 plan would embrace it.
Condition:Too fragmentary for re-use.
BRICK AT 38Brick:In size is 9" x 4¼" x 2½" one course deep of stretchers.
Mortar:Tops of bricks show traces of oyster shell lime mortar with heavy shell aggregate.
Probable Use:Note that this brickwork is not similar to that at 37 and 39, nor similar to 36. It is so fragmentary that it is hard to relate it to other brickwork or note its purpose. It may have been related to the two outbuildings in this area shown on the insurance policies.
Condition:Too fragmentary for re-use.
BRICK AT 39Brick:Size 8½" x 4" x 2¾" two brick - one course deep.
Mortar:Similar to 37.
Probable Use:It is too fragmentary to state its purpose. It may have been related to 37 in some way, but does not relate to 36 in brickwork or position.
Condition:Too fragmentary for re-use.

MAIN FOUNDATIONS

There are two types of brickwork in this foundation with two corresponding brick sizes. These represent two periods and can be identified by the legend on the plan for hatching. A third, but less important type, is found in the South wall along the street line outside the building. The types may be called:

Period I- Size 9" x 4¼" x 2½"
Period II- Size 8¾" x 3¾" x 2 7/8"

WEST WALL
17-25

From 17 to 22 the brick are period I laid in English bond, but most of this wall is missing. At 22 and Northwards are two fragments of the wall, the more Northern of which extends under the chimney foundation at 23. At 18 are the fragmentary remnants of a cellar entrance, the brick being period I. At 21 the pavement of the basement floor is missing and one period I brick remains at a lower level surrounded by mortar. The fact that this brick exists, together with the missing paving and section of outer wall, leads to the assumption that there was a chimney here. The remains of the wall 17 to 22 are not fit for re- use.

The chimney 23 and wall North of it to 25 are of period II brickwork, laid in English bond. As noted above the chimney overlaps the first period wall. The chimney and wall north of it are bonded together. The chimney projects beyond the West face of the period I wall 5". The South face of the chimney shows how the main cross wall 23-3 stood against it and the mortar indicates an unbonded butt joint. This cross wall is missing at the point under consideration. The chimney and wall North of it are fit for re-use.

13

The cellar entrance at 18 is a very rough piece of brickwork. It projects well West of the street or building line of colonial times. This may be the reason it was changed to the South wall at 28. It may never have been completed at all or it may have been changed by later alterations. At the bottom it is bonded in with the brickwork of the building wall and is likewise period I.

NORTH WALL
25-1

This wall has one portion missing at 10-9. The type of brick is period II and continues the brickwork 23 to 25.

EAST WALL
1-4

The Northern portion of this wall 1-2 is of the same period and kind of brick as the North wall 25-1. The corner at 1 is peculiar in that the Eastern face of it is rough brickwork with joints not tooled due to the fact that this wall was built against the dirt face of the excavation for the basement. This face is also uneven and is only bonded at the corner to the North wall on the inner face brick of the basement, leaving a vertical joint filled with mortar as shown on the plan.

At 3 a portion of the interior longitudinal wall 23-3 is left - see elevation "F. F." The wall 1-2 butts this wall and is not bonded thereto. Wall 3, also, is period I brickwork similar to wall 17-22. Wall 3 in turn butts the East wall 2-4. Wall 2-4 is the same kind of brick as 3, but projects slightly North of it to an uneven termination. Note that a similar projection and termination occurs at 22. All the east wall 1-2-4 is in a condition fit for re- use, - is laid in English bond with a good, hard oyster shell lime mortar. 14 This is true of wall 3. Note the slots in the wall 1-2 at F - see elevation "F. F." These slots may have been rebates for storage shelves.

SOUTH WALL

Parts of this wall are missing from 5 to 16. It is all in English bond and of Period I. At 17 the cheek of the bulkhead entrance is bonded to it. At 28 it is interrupted by a bulkhead entrance, the cheeks of which are made of Period II brick. Only part of these steps is left, the upper portions have disappeared except the remnants of the top step along the line 27-29. The cheeks have slots left in the brick for wood nosings, one of which in part remains at the bottom step. It is of cedar, badly rotted and shows signs of having been subjected to fire. There is a rebate in the brick at each end for a wood frame - this seems obvious because the ends of the cedar nosing have slots for tenons and holes for pegs showing that the frame was joined to the nosing with mortices, tenons and pegs. Although the other nosings are missing, they all had beds of mortar. See section "A. A". Note in this section the remnants of paving. Since it runs under the present sidewalk, it is not possible at this writing to ascribe a given period to it.

At 32 is a solid piece of brickwork of Period I. It is in English bond and seems to be the foundation of the front steps. Just South of the step foundation is a series of bricks one course deep. The top surfaces of these are worn and seem to be remnants of paving which lead from the sidewalk to the front steps. The grade at this point can therefore be considered as slightly above the adjacent original ground or paving level or grade.

15

From 35 to 33 is a curb composed of a single course of brick. The brick size is 8½" x 4" x 2 5/8" and forms a third general size as mentioned above. At 35 and 34 this brick is interrupted by small gaps. Where the brick terminates at these points closers have been used indicating that the brick were laid in English bond and formed a wall. Also in excavating at these gaps holes were found filled with loose debris and doubtless held posts. The wall is interrupted by the front entrance paving but continues at 31 to 29 leaving small breaks at 29 and 30 like those at 34 and 35 and equidistant from them about the front steps as a center line. The bulkhead interrupts the wall which continues beyond it to 27 where there is another post hole and where it turns North ending on a line of a brick gutter. At 26 is a small piece of brick which may be more of this wall or may not. As the Northern angle is approximately on the colonial street or building line, 26 may be a casual fragment of some kind. Here also is a bit of gutter and in its middle is a large hole which may have been some sort of drain or perhaps a post hole. This hole was full of debris and was excavated three feet deep. The wall from 35 to 33 is one course thick,but from 31 to 27 it is three courses thick and in English bond and laid in oyster shell lime mortar.

All the area North from this wall to the building and South to the Street line shows traces of marl, crumbled brick rubble, etc. It may all have been paved, using the layers of marl and rubble for a base, but no actual paving was found. The wall itself is similar to several examples noted in photographs of English Georgian buildings where a thin brick wall about 1½ feet high is interrupted by posts which support a wooden paling resting on the curb wall.

16

BRICK AT 40

Laid in English bond - size 8½" x 3¾" x 2 7/8" with some 9" x 4¼" x 2½" brick mixed in. It is two courses deep and rests on a bed of partly burned coal broken into small fragments. The mortar is oyster shell lime mortar.

BRICK AT
41 and 42

Two courses deep - same kind of brick as at 40. 42 is three courses deep.

BRICK AT 43

Two courses deep of same type brick as 40-41-42. The insurance policies indicate a "back-porch" 20 x 12 feet at this location. These scattered fragments of piers and walls must have been related to it. Since this porch may have been contemporaneous with the insurance policies (1806) and therefore late, the late type of brick in the fragments can be explained. 41 and 42 are heavier masonry than 40 and 43 and may have been earlier step foundations.

WITHIN THE BASEMENT WALLS

The basement is divided by various partition walls of brick into six portions. See notes above on cross wall 23 - 3 under East wall and West wall.

17

WALL
16-11-10

This wall is in English bond of period II brickwork. Only the footing courses are left at 16 and do not touch the South wall. At 11 the wall terminates and shows traces in the mortar coat on the North face where wall 23-3 ran past and which it butted without bonding. At pier North of 11 is the same type of brick, the Southern angle of the pier being thicker than the other portions of the wall. At the North end of this are the indications of a door opening with a slot in the pier for the missing wood sill and a rebate in the paving with a mortar bed for the sill. This is similar to section "E.E." At 10 the wall is missing, but a few brick indicate the North jamb line of the door opening.

WALL
6-7-8

This wall is of the same period II brickwork as 16-11-10. At 6 it terminates on the line of the South wall allowing for a mortar joint. North of this is a door opening similar to that at 11-10 and 8 and shown in section "E. E." The North jamb of this door is a pier as the wall 23-3 ran past and was butted by it as at 11. The brick in this pier steps back at top from 13½" typical wall thickness to 11½". The wall continues North of 7, and shows the same buttered mortar surface where it butted walls 23-3. On the West side of the South part of this wall is a slot similar to those at F on the East wall. On the East face of this wall are two breaks. At 8 is another door whose North jamb pier butts the North wall without bonding. The door treatment at 8 is the same as for door near 7 and one at 11-10. Note that although the brick of wall 6-7-8 is the same as the North wall 9-1, the two do not bond at the intersection at 8.

18

PAVING

All the basement floor was covered with neat, brick paving in a running pattern in directions as shown on the drawing. At the outer walls it was stopped short providing a gutter about 2 to 2" wide. See section "G. G." The bottom of this gutter was formed by other brick set close to the wall and acting as a curb to the 3" thick bed of pure sand on which the paving rested. The paving was made of 1/2 and 3/4 brick for the most part, although some whole brick are in evidence. The joints are dry except for a distance of 4" in from the gutter where they are filled with oyster shell lime mortar. The brick at the bottom of the gutter are also laid in mortar. The bed of sand under the paving of the eastern half of the basement seems to rest directly on undisturbed clay, but that of the western half rests on a fill of debris with some brick admixed about one foot deep.

At 20 two gutters were found leading to a small pit with brick walls and bottom - see sections "B. B." and "C. C." The gutters had been bricked up flush with the floor while the pit was full of ashes and fill and was also covered by a continuation of the paving. Its purpose must have been as a sump pit, later filled in.

CHIMNEY AT
12-13-14-15

Upon removal of paving at this point, the chimney foundation was discovered. It is of period I brickwork. The fireplace paving or under-fire bricks show heavy traces of fire and are discolored. Joints are full of ash. These bricks are of a different size - 8" x 3¾" x 2 7/8" - same as period II.

19

The present foundation indicates a large fireplace and chimney at 13 with another breast extending eastwards at 14 and 15. This latter breast is fragmentary and does not indicate its original shape clearly. See further remarks under general considerations.

WALL AT
24

This is laid in English bond of period I brickwork. It is a fragment of wall 23-3.

20

GENERAL CONDITIONS

OUTBUILDINGS

Starting with the insurance policies 4 outbuildings are indicated, a kitchen, a dairy, a smoke house and a stable. The stable was at the rear of the lot but no trace of it was found in excavating. A foundation was found which corresponds to the kitchen indicating a building of the same size and position as shown in the policies. South of it, where the policy indicated the dairy, was found a wall fragment which is in agreement with the policies and bears them out.

At 52 and 64 are the fragments of another structure which may be assumed as similar in shape and size to the kitchen.

South of this is the well, with a gutter and large paved area and a circular foundation. As mentioned above the area of paving would seem to have been enclosed by a structure of some sort which included the round foundation also. Such a structure is not mentioned in the insurance policies, nor shown on the Frenchman's Map. It may have post-dated these documents.

The fragmentary foundation West of the well at 51-45 is later than either the kitchen or the North building. Neither the Frenchman's Map nor the insurance policies show any structure at this point.

21

With the foregoing in mind, the probable arrangement of outbuildings from the evidence consisted of the kitchen, dairy, and smoke house, a building similar to the kitchen North of the well, no building at the West unless one based on the chimney alone disregarding the late walls and possibly some structure combining the paving and round wall near the well, or a well-head, a round brick structure and an area of paving.

Although several additional outbuildings are suggested in the Prentis inventory, the foundations found on the site would accommodate them.

MAIN FOUNDATION

The first part of the structure seems to have been a house which included walls 17-16, chimney at 13-15, wall 17-22 and cellar entrance 18-19. This represents a house about 16 x 25 feet, fronting the West as mentioned in the deeds. This was extended soon after to include 5-4-2 and 3 to 12 as it is the same kind of brickwork - period I. Later, wall 23-25-1-2 was erected including interior walls 16-10 and 6-8 as well as the paving and new bulkhead 28 - all being period II brickwork. Later than this the South fence wall 27-35 was built followed by the rear porch at 40-43. This sequence fits with the deeds as well as the foundations and is similar to the growth of like structures in Williamsburg which began with small units and increased with additions such as the Blair House.
