possibly be devised. Outer walls wind and moisture proof, and inner
walls of brick, with an absolutely protected air space between, insure
strength and warmth. An interior wall finish of the hardest and most
non-absorbent materials known for such uses is a valuable hygienic
provision, and both safety and salubrity are further conserved by an
absence of any hollow spaces between floors and ceilings, or in stud
partitions. No vermin retreats, no harbors for rodents, no channels for
flame exist. Heating is accomplished by indirect radiation with the
steam supply from the power house, but there are many open fireplaces to
add to the complete stack and flue system of ventilation.

Attached to the central group and completed are the kitchen building,
the laundry building and a dwelling house for employes, which are so
disposed in the rear of the group as to make a courtyard of value for
the resort of patients, as the main buildings protect and shelter it.
These buildings are ample for their work when the institution's full
capacity is attained. The kitchen building is a particularly interesting
one. All of the cooking is to be done there, and a system of subways,
with tracks on which food cars are run, connects it with all of the
groups. An idea of the magnitude of kitchen plans for such an
institution may be got from one single fact. The pantry is a lofty room,
20x32 feet.

The calculation that 80 per cent. of the insane of the district would be
in the chronic stages of the disease explains the provision in detached
cottage groups for this proportion of the patients. A great proportion
of these are feeble and helpless, requiring constant attendance night
and day, but attendance that can be given cheaply and efficiently in
associate day rooms, dining rooms and large dormitories. Detached group
No. 1, which is completed, is an infirmary group for patients of both
