Much, however, yet remains to be done, and associate or private energy is needed for the trial of new and not less important experiments than that already well performed. The means for some of them are at hand. It will be remembered that the late Hon. Abbott Lawrence, to whose beneficence during his life the community was so largely indebted, and whose liberal deeds will long be remembered with gratitude, left by will the sum of $50,000 to be held by Trustees for the erection of dwellings for the poor. This sum will in a short time be ready for employment for its designated purpose, and it may be hoped that those who control its disposal will not so much imitate the work already done as perform a work not yet accomplished, but not less essential. The houses of the Association are, as we have stated, not occupied by the most destitute poor,--and it is for this lowest class that the most pressing need exists for an improvement in their habitations. If the cellar-dwelling poor can be provided with healthy homes, and these homes can be made to pay a fair rent, the worst evil in the condition of our cities will be in a way to be remedied. It is very desirable that a house should be erected in one of the crowded quarters of the city, and at a distance from the buildings of the Association, in which each room should be arranged for separate occupation. The rooms might be of different sizes upon the different floors, to accommodate single men who require only a lodging-place, or a man and wife. Perhaps on one floor rooms should be made with means of opening into each other, to supply the need of those who might require more than one of them. The house should be heated throughout by furnaces, to save the necessity of fires in the rooms; and as no private meals could be cooked in the house, an eating-room, where meals could be had or provisions purchased ready for eating, should form part of the arrangements of the house in the lower story. There can be no doubt that such a house would be at once filled,--and but little, that, if properly built and managed, under efficient superintendence it would pay well, at the lowest rates of rent. Even with a possibility of its failing to return a net annual income of six per cent upon its cost, it is an experiment that ought to be tried,--and we earnestly hope that the Trustees of Mr. Lawrence's bequest will not hesitate to make it. Putting out of question all considerations of profitable investment, it would be, as a pure charity, one of the best works that could be performed. We must restore health to our cities, and, to accomplish this end, we must provide fit homes for the poor. The way in which this may be done has been shown. * * * * * A SHORT CAMPAIGN ON THE HUDSON.
