In the ten years from 1891 to 1901, while the population increased from 457,772 to 573,579, or 25.3 per cent, the number of dwelling-houses increased from 53,429 to 65,600, or 22.8 per cent, not quite keeping pace; and though not a few of the new buildings are capacious tenement houses, yet actual conditions have probably not improved. It is to be noted that 4 per cent of the dwellings are vacant.

2. The facilities for the building of new houses in the suburbs steadily increase. The suburbs of Boston are deservedly healthy and are ample for a vast population.

The President of the Boston Elevated Railway Company has furnished the following statistics, which show in the last five and ten year periods a marvelous development and explain the exodus outward from the crowded centre into happy and healthy suburban life on some of the hundred hills which make these suburbs so attractive. This outward migration shows no sign of culmination, but is still under full headway.

The running time of the cars has improved so that it now averages nine miles per hour on the whole system, against six miles or less ten years ago when horses were used, and within the last five years it has been reduced about 8 per cent. The track mileage increased from 260 miles in 1891 to 296 in 1896 and 408 in 1901. “For the year ending September 30, 1891, we ran 2,326,274 trips, 17,462,572 miles, carried 119,264,401 revenue passengers and 8,466,311 free transfer passengers. The average length of each trip at that time was 7.5 miles. Five years later we ran 2,822,142 trips, 25,841,907 miles, carried 166,862,288 revenue passengers and 17,566,361 free transfer passengers. The average length of each trip was 9.16 miles. Five years later, or for the last fiscal year, we ran 3,883,737 trips, 43,631,384 miles, carried 213,703,983 revenue passengers and 65,000,000 free transfer passengers. The length of each trip had increased to 11.23 miles.”

The co-operative bank system has greatly promoted the construction and separate ownership of the modest and cosy little homes springing up so rapidly in all the suburbs of Boston. The Pioneer Bank was started in 1877, and to-day there are in Boston eighteen of these co-operative banks with a capital of $5,029,478, nearly the whole of it loaned out on small estates. A score of years ago it was no easy matter to obtain a “building loan,” but co-operative banks have perfected the system of loans to builders upon houses “in process of construction.” The admirable process of small monthly payments not only educates the borrowers into habits of saving, but in a few years reduces the loan, so that the old-fashioned savings banks with their immense capital can take up at lower rates these loans, when they are reduced to the statute limit of 60 per cent of the value of the estate. Hence it is the case that the $5,000,000 of co-operative bank capital by no means measures the full beneficial influence of this system in the growth of suburban homes.

3. The influence of philanthropic enterprise, compared with that of private business, has been insignificant.

Three incorporated societies are working in a small way, the oldest, the Boston Co-operative Building Company, chartered in 1871. With a capital of $292,000, it has about $400,000 invested in seventy-eight houses with 985 rooms, occupied by 311 families containing 1,023 persons.

The Harrison avenue group of twenty-four three-storied brick houses—each, except the corners, arranged for three families—has attracted deserved attention, with its hollow square in the centre, tastefully arranged as a playground for the children, and a bit of beauty for the parents.

The company has just started to reproduce this hollow square on its last purchase of 33,000 feet on Massachusetts avenue. Mr. A. W. Longfellow, the architect of the Harrison avenue group, furnishes this plan of a corner and a normal interior house just completed on Massachusetts avenue, showing the latest developments of model tenement house design, and also a land plan.

The thirty-one years of life of this company show many vicissitudes; 7 per cent being earned for some years, and then from 1876 to 1889, dividends were stopped or reduced to 3 per cent and earnings were invested. Recently dividends have been 6 per cent or 5 per cent. But the capitalization of undivided profits has been so large, that it is not possible to ascertain what the just annual earnings are from year to year, and hence the educational influence is lost upon other capitalists who might be incited, by a clear and exact statement of facts, to follow the most commendable lead of this company in building the very best model tenements and having them managed by the considerate care of women agents.
