the nematode worms (paragraph 385) can destroy the older 

 roots. 



514. Formula. A fair proportion of acid phosphate 

 is customary in all tobacco fertilizers, but an excess of 

 this constituent has been found to injure the quality of 

 the leaf. A complete fertilizer similar in composition to 

 one in common use in North Carolina may be made as 

 follows : 



300 pounds acid phosphate per acre, 



50 pounds nitrate of soda, 

 200 pounds dried blood, and 

 150 pounds high-grade sulfate of potash. 



For shade-grown Sumatra tobacco, the amount of fertilizer 

 used is several times larger than indicated above. For this pur- 

 pose A. D. Shamel recommends the following kinds and amounts 

 per acre : 



1000 pounds cotton seed, 

 1000 pounds cotton-seed meal, 

 300 pounds carbonate of potash, 

 700 pounds fine ground bone, 

 800 pounds lime, 

 3800 pounds, total. 



515. Types and varieties of tobacco. " The principal 

 types of tobacco are the following : (1) Cigar wrapper and 

 binder ; (2) cigar filler ; (3) chewing or plug ; (4) smoking ; 

 (5) export tobaccos." Types refer chiefly to the principal 

 use made of each kind, and to the market for each. 



Cigar wrapper and binder tobacco is produced from 

 several widely different varieties, the kind commanding 

 the highest price being the Sumatra, grown under cloth 

 or slat shade, chiefly along the Gulf coast. The best of
