EXPENSES FOR HEAT AND LABOR. 13 
MINNESOTA — 
12. In one season I used 470 tons of Illinois coal (cost- 
ing $1,424) in four houses 16 x 200 ft., four houses 16 x 100 
ft., and nine houses 20 xgo ft. The next season I added 
two houses 35x 200 ft. each, and then used 850 tons, 
costing $3,238. By rearranging the steam pipes, I heated 
these same houses the following two winters with 649 
tons and 608 tons respectively. 
INDIANA— 
13. I use natural gas, and cannot give figures. 
One good man should attend to four such houses, if he 
has help for four weeks in planting, etc. 
14. A three-fourths span house, 20 ft. wide and rr ft. 
high, in an exposed place, cost us in 1895-6 at the rate of 
$89.04 for a house too ft. long (coal $2 per ton). We can 
reduce this figure somewhat by careful management. An 
equal span, 20 ft. wide and to ft. high, cost us about 
$35.20 per too ft. This house is on the sheltered side of 
the range. (This correspondent is on the Ohio river.) 
One good workman should attend to about five such 
houses, in roses. 
ILLINOIS— 
15. It cost me last winter (1895-6) for coal, for rose 
house 20x Ioo ft.,— as nearly as I can figure the propor- 
tion,— $50, with soft coal at $2.30 per ton, and the use of 
some slack at 75 cents and $1 per ton. This house is 
three-fourths span and 12 ft. high. 
In my place, where cut flowers and pot plants are both 
handled, and with a retail trade to wait on, it requires 
about one man to a house 20x 1ooft. If I were growing 
only roses, I should not need so much help. 
PENNSYLVANIA— 
16. Such a house in roses here (Philadelphia) would 
require about 12 tons of pea coal at $3.25, or 9 tons of 
larger size at $5.50. 
An experienced rose grower ought to manage 5,000
