Preparation of Bed 



During Winter deep the snow out by a covering of boards. In 

 the middle of March, or six or eight weeks before plants can be safely 

 put out of doors, if the bed has been constructed as directed, two feet 

 of fresh manure is placed in the frames. Nothing but fresh manure 

 will suffice, horse manure being best, which has been piled and turned 

 several times to bring to a uniform temperature. As placed in frames, 

 the manure should gradually be stamped rather firmly. To insure 

 more uniform heating a layer of straw is used to cover the manure. 

 Soil which has been stored in basement is then spread over to*a depth 



One of the King Construction Co.'s double-glazed frames, a very valuable type 



of four inches. The soil should be rather sandy and should consist of 

 good loam, leaf mold, sand and some well decayed manure. Put on 

 the sashes and, as Mrs. Rion, in "Let's Make a Flower Garden," says: 

 "Let her biJe." It will steam tremendously for four or five days, then 

 it gets down to regular business of more or less even heat. There are 

 nice thermometers to be had to take the bed's temperature; find out 

 when its fever has dropped below ninety degrees; then you know it is 

 t me to go ahead and plant.
