in case of rain. For a permanent frame, use good Cedar posts and 

 always be sure that you have plenty of drainage. 



Often it is found advisable to construct frames which can be 

 moved about and for such, 12-ft. planks are best. This length will 

 give you room for four sashes. 



Every man should figure out for himself just what will meet his 

 own requirements best and work accordingly. Those located in 

 southern sections won't need as heavy frames as are necessary in 

 the North; yet in either case the more substantially they are con- 

 structed, the better. There isn't a retail grower anywhere who 

 cannot use frames to good advantage, almost, one might say, nine 

 months out of every twelve. 



THE SOIL 



The smaller and more delicate the roots of a plant, the finer and more 

 mellow should be the soil you use for potting. Heavy roots usually 

 like a strong or heavy soil, but in all cases, perfect drainage is es- 

 sential in order to promote a healthy growth. Good soil and perfect 

 drainage must go together if you want results. As long as you have 

 perfect drainage, you can feed plants in poor soil, and have success, 

 but the best soil without good drainage will soon become sour and 



useless. 



XpOR general purposes a soil on which you can grow a good crop 

 -*- of Timothy, Clover or Red Top will do nicely. If it is heavy 

 enough it will also grow good Roses and answer for your palms.
