The suggestions on the location and management of hot- 

 beds apply equally well to cold frames. 



165. Grading. — If the ground is uneven or sloping, it 

 should be graded before placing or making the frames. 

 Level ground is important for effective watering. When, 

 for example, flats do not set level in the frames, much of 

 the water applied with a hose will run off before it has 

 time to percolate. This may also be true of solid beds,

 with some material that will afford additional protection. 



166. The frame. — Cold frames are less expensive to 

 make than hotbeds. Their construction is more econom- 

 ical in three particulars: (i) Excavation is not necessary 

 when vegetable plants are grown. (2) Heating material 

 is not needed. (3) The frame itself requires less material. 



Many of the points made in considering the frame and 

 sash for hotbeds apply equally well to cold frames. As
