MATERIALS AND METHOD 



To raise grape seedlings, it is only necessary 

 to gather the seed from the variety desired, and 

 keep them barely moist until planting time. 

 Plant as soon as the frost is out of the ground 

 in well-drained land, in rows about three or 

 four feet apart. Scatter the seed thinly in nar- 

 row drills. Cover with sandy or leaf-mold soil, 

 about one inch deep in a humid climate, a little 

 deeper in dry soil like that of California. 



In the latter case it is well to have the upper 

 half of the covering of sawdust, so that the seed- 

 lings do not have too great a weight to lift in 

 pushing through the soil. 



During the summer the very poor seedlings, 

 those which are attacked by mildew or which 

 have made weak, uncertain growth, may be up- 

 rooted at once, giving the others a better chance. 

 Later, while the plants are dormant, transplant 

 the most promising of these to rows about twelve 

 feet apart, the individual plants being from one 

 to two feet apart in the rows, according to the 

 variety. 



Like most other cultivated fruits, grapes do 

 not come true from the seed. Among Ameri- 

 can grapes, if seeds from a vine bearing black 

 fruit are planted, about ninety-nine out of one
