complete separation of each set of apartments from the others, each one
opening by a single door upon the common stairs or passage. Their relation
is scarcely closer than that of separate houses in a common continuous
block. Each tenement, it will be observed, consists of a living-room, and
two or three sleeping-rooms, according to the space, a wash-room, with sink
and cupboards, and a water-closet. The stories are eight feet and six
inches in height, which is ample for the necessities of ventilation. In one
of the buildings, each tenement is provided with shafts for dust and offal,
communicating with receptacles in the cellar. The roofs of both are fitted
with conveniences for the drying of clothes, properly guarded; and in the
cellars of both are closets, one for each tenement, to hold fuel or
stores. In the basement of house No. 1 there are also two bathing-rooms,
which have been found of great use.

It would be difficult, after some years' experience, to pronounce which of
the two houses is the best fitted for its object. Their cost was nearly the
same. The plan of No. 1 is original and ingenious; its large open central
space is valuable for purposes of ventilation, and as affording opportunity
for exercise under cover in stormy weather for infants and infirm
people. This advantage is perhaps compensated for in the other house by the
fact of each tenement reaching from back to front of the house, thus
securing within itself the means of a thorough draught of fresh air. Both
plans are excellent, and may be unqualifiedly recommended.

The houses were ready for occupation about the beginning of 1855, and since
