READY FOR POLLINATION 



In the upper part of the photograph are shown three baskets of flower-buds which, after being 

 washed, have opened out and are ready to shed their pollen. Below are three glass 

 vials with camel's hair brushes and some pollen ready to be used in cross-pollination. 

 (Fig. 6.) 



may be resorted to. In the former case 

 the brush is used to expedite the actual 

 crossing of the flowers, while in the 

 latter cases economy of pollen deter- 

 mines the method. 



When all of the flowers are cross- 

 pollinated the bags are replaced and, if 

 these happen to be made of a thin 

 fabric, are left on the vine until the re- 

 sulting fruit, if any develops, can be 

 harvested. 



STARTING THE SEEDLINGS 



Grape seedlings may be started in 

 various ways. The one-seed-to-one-pot 

 method, when used in a greenhouse, be- 

 comes too expensive because the pots 

 take up too much space ; when used out 

 of doors it is unsatisfactory because 

 uniform conditions of moisture are 

 difficult to maintain. 



When greenhouse facilities are avail- 

 able, seeds which have been stratified, 

 should be drilled about one-half inch 

 deep in flats filled with a good, light, 

 greenhouse soil. If no such facilities 

 are available then the seedlings may 

 be started in a similar soil but planted 

 direct in a glass-covered cold-frame. 

 Probably the only advantage obtained 

 by starting the seedlings in a greenhouse 

 is earliness. This method is especially 

 recommended for seeds which have been 

 obtained from flowers that were self- 

 pollinated, because the resulting plants 

 from such seeds are apt to lack vigor. 



After the plants have attained a 

 height of 3 or 4 inches they can be set 

 out into nursery rows, in very much the 

 same manner as cabbage plants are and 

 without any serious setback. It is best, 

 however, to shade the newly trans-
