Each house will be equipped with hot water heat furnished from a central station; electric lights, electric power, telephone connected with central station, vacuum sweeping system, complete plumbing and water supply.
The calculations which are given herewith are fairly close and without doubt under proper management and accessible facilities for getting material the work can be done for the estimate given.

| Gas and vacuum producers and holders | 10,000 |
| One mile of house—equipped | $777,250 |
| Cost per house—equipped | $3,109 |
The principal fixed charges for labor, coal, interest on the investment would be as follows:
| Chief engineer | $2,400 |
| Two (2) assistant engineers, $80 per month, $960 each | 1,920 |
| Four (4) firemen, $60 per month, $240 each | 2,880 |
| Two (2) extra men, $50 per month | 1,200 |
| Chef, $75 per month | 900 |
| Three (3) cooks, $40 per month | 1,440 |
| Four (4) helpers, $20 per month | 720 |
| One (1) laundryman, $100 per month | 1,200 |
| Ten (10) women, $20 per month | 2,400 |
| Total labor cost | $15,060 |
| Coal | 4,000 |
| Oil and waste | 500 |
| 6% interest on $581,250[B] $34,375 | |
| 7% ” ” 196,000[B] 14,550 | 48,852 |
| Total expense for one year’s operation, interest and depreciation | $68,385 |
[B] The lower rate of interest is charged upon the house and fixtures, the higher rate upon the plants and machinery.
Or each tenant’s rent for year to be $22.76 per month or $3.25 per room, exclusive of charge for food but inclusive of furniture, power, cooking, heat, light, water, vacuum sweeping, laundry and the delivery of all food, parcels, produce, etc.
The population could without doubt be increased by 500 to 1,000 houses more without any material increase in the principal items for labor, such as engineers, firemen and heads of departments. The only extra increase would be for help in these departments which would be governed by the amount of work required.
