“3. Two wings, each three stories in height; the one, in the female department, containing the dormitories and bathing-rooms for the girls; the other, in the male department, containing the boys’ dormitories. “4. A building, two stories in height, near the southern wall of the male department, the first and second stories of which are designed for work-rooms, and the basement for a washing and bathing-room for the boys. “A corridor, 12 feet in width, extends the whole length of the main building and wings, a distance of 243 feet. “Many important points, in addition to the classification of the inmates, claimed the attention of the Board, in the preparation of the plan--_e. g._ security against the escape of the inmates, and their constant supervision by an officer at all times of the day; the proper ventilation and warming of all the apartments; provision for out of door exercise for the inmates in all states of the weather, &c. These, it is believed, have all been kept in view and provided for, in the plan adopted. “The wall of enclosure, excepting the gate-way and a portion of the pointing, is completed; the work-shop is finished; and of all the other buildings the walls are up, the roofs on, and a small part of the flooring laid.” Extracting flues, connecting with shafts leading to the external air, have been inserted in all the dormitories and other rooms, to ensure a good ventilation at all times; and suitable arrangements have also been made for heating the different apartments. We trust the Managers have succeeded in securing these two most important requisites to the health (physical and moral) of their new institution. A full supply of good water, fresh air and wholesome warmth, is what every institution of the kind wants; and yet in one or more of them almost all are deficient. The second document, at the head of the present article, shows a prosperous state of the institution of which it treats. The whole number of children and youth who have found refuge within its walls is 4,397. Of these, 568 were under its care, at different periods, during the year 1848. The number remaining January 1, 1849, was 355; and 213 were disposed of during the year. The chief branches of labor are, making and seating chair frames and manufacturing razor strops. Among the improvements of the year is the introduction of a small steam engine, to relieve the severity of some parts of the labor, which is not unfrequently prejudicial to the immature strength of the inmates. The disbursements of the year amounted to $22,896 10, and the receipts $24,122 32. Of the latter sum, $7,198 77 is from the labor of the inmates, $7,323 83 from the State, $4,600 from the city of New York, and $4,026 50 from theatre and circus licenses. The chief items of expense were food and provisions, $9,106 41; salaries, $4,875 89; clothing, $2,297 90.
