According to the out different schemes of payments to suit the needs of purchasers. For censns of 1880 there were in Baltimore 50,833 dwelling houses and a popu- example, a house worth in fee $5,000 will be sold for a cash payment of lation of 332,313, making an average of about six and one-half persons to $1,100, subject to two mortgages; the second one, of $400, is to be paid off each house. New York in the same year had 1,206,299 population and in five years, and the other for $3,500 to remain. At the end of five years 73,684 dwelling houses, an average of nearly sixteen persons to each house, arrangements are made for the first mortgage in a similar way. The total while over laalf tlae population was crowded into tenements. In 1884there payments on interest and principal until the entire debt is paid will be were in Baltimore only 1,122 houses containing three families and over twenty dollars per month, which would be much less than an ordinary rent and knownas tenement houses, the total number of inmates in these houses for the same property, although it includes an annual payment of $80 on the being 14,838, or an a.verage of about thirteen to each house. principal.

A cash payment of $425 can be made and monthly payments homes has been the system of leasing land on so-called irredeemable ground of $35 for the first five years. A more common method is for the purchaser rents, which was in vogue in Baltiniore and its immcdiate suburbs down to to pay down a certain sum, say 500, and then make yearly payments of $500 the year 1888.
