If this is true from a purely economic point of view, what then of the outlook from the Christian standpoint? Not long ago a great meeting was held in this city, of all denominations of religious faith, to discuss the question how to lay hold of these teeming masses in the tenements with Christian influences, to which they are now too often strangers. Might not the conference have found in the warning of one Brooklyn builder, who has invested his capital on this plan and made it pay more than a money interest, a hint worth heeding: "How shall the love of God be understood by those who have been nurtured in sight only of the greed of man?"

The first tenement New York knew bore the mark of Cain from its birth, though a generation passed before the writing was deciphered. It was the "rear house," infamous ever after in our city's history. There had been tenant-houses before, but they were not built for the purpose. Nothing would probably have shocked their original owners more than the idea of their harboring a promiscuous crowd; for they were the decorous homes of the old Knickerbockers, the proud aristocracy of Manhattan in the early days. It was the stir and bustle of trade, together with the tremendous immigration that followed upon the war of 1812 that dislodged them. In thirty-five years the city of less than a hundred thousand came to harbor half a million souls, for whom homes had to be found. Within the memory of men not yet in their prime, Washington had moved from his house on Cherry Hill as too far out of town to be easily reached. Now the old residents followed his example; but they moved in a different direction and for a different reason. Their comfortable dwellings in the once fashionable streets along the East River front fell into the hands of real-estate agents and boarding-house keepers; and here, says the report to the Legislature of 1857, when the evils engendered had excited just alarm, "in its beginning, the tenant-house became a real blessing to that class of industrious poor whose small earnings limited their expenses, and whose employment in workshops, stores, or about the warehouses and thoroughfares, render a near residence of much importance." Not for long, however. As business increased, and the city grew with rapid strides, the necessities of the poor became the opportunity of their wealthier neighbors, and the stamp was set upon the old houses, suddenly become valuable, which the best thought and effort of a later age has vainly struggled to efface. Their "_large_ rooms were partitioned into _several smaller ones_, without regard to light or ventilation, the rate of rent being lower in proportion to space or height from the street; and they soon became filled from cellar to garret with a class of tenantry living from
