PROPAGATION. 267

 be nicely adjusted to meet the changes that are 

 constantly occurring. Painting with white lead, 

 sanding, etc., are usually resorted to ; but a bet- 

 ter plan is given below. 



By our arrangement of making the sashes face 

 the north, the necessary conditions are obtained 

 with much less labor, and with a much greater 

 degree of uniformity ; and this latter point is of 

 the utmost importance. Not having to battle 

 constantly with the direct heating rays of the 

 sun, less ventilation is needed, and the proper 

 degree of heat and moisture is more easily and 

 uniformly maintained. We have found the la- 

 bor to be reduced fully one half, and the success 

 increased much beyond that amount; besides 

 which, the plants are of a better character. 

 A good plan for shading is to make a light
