HOME PROJECT 367 



EXERCISES 



1. Make a working drawing of a hotbed 12 feet by 6 feet, 

 showing the back of the frame 6 inches higher than the front 

 and a pit 2 feet deep, filled with 12 inches of manure, and 

 covered with about 4 inches of soil. 



2. If there are any greenhouses in the neighborhood, make a 

 trip to see them, taking notes on the method of heating, width of 

 glass, ventilation, and the crops raised. 



3. Draw a diagram of a cold frame to grow tomato plants. 



4. What are the principal requirements of a good soil for 

 greenhouses ? 



SCHOOL GARDEN WORK 



The class should construct a hotbed in the school garden. 

 Note in detail the material used in construction and estimate 

 the cost of the material; also describe the general method of 

 procedure in its construction. Insert a soil thermometer in 

 the soil after finishing and note the temperature of the soil 

 each day until ready for seeding. 



HOME PROJECT 



Make a working drawing of a hotbed covering at least 36 

 square feet of space. Estimate the material required for the 

 same. Construct the hotbed at least a month before outdoor 

 planting weather. Sow tomato, cabbage, celery, cantaloupe, 

 and other vegetable seeds to produce a sufficient supply of these 

 plants for the home garden. Seed the remainder of the bed to 

 lettuce and radish. Ventilate, water, and otherwise care for 

 the bed as outlined in the text. Transplant at the proper time, 

 and harden plants before transplanting to the field. Keep an 

 accurate record of each day's work.
