per 100 pounds. The cost of producing it, including* such items as 

 taxes on the land, wear and tear of machinery, and all the other oper- 

 ations, from breaking the land to ginning the product, computed for 

 the lint, was 4^ cents per pound. There was consequently a margin 

 of profit in plat 1 of $25.24 per acre; on plat 2, of $13.79 per acre, 

 or an average on the 50 acres of early cotton of $19.51 per acre. Reck- 

 oning the loss incurred in working plats 3 and 4, which produced noth- 

 ing, at $6 per acre, there was nevertheless a net margin of profit on 

 the 100 acres of $6.76 per acre. A tabular statement of these results 

 follows: 



PLAT I. 



Value of yield, 34,435 pounds in seed (11,475 pounds lint), at |3.25 per 



100 pounds $1, 119. 13

PLAT II. 



Value of yield, 18,785 pounds in seed (6,250 pounds lint), at $3.25 per 



100 pounds 610. 51

It may be added that the proprietor of the plantation upon which 

 this work was conducted had 300 acres in improved cotton (not under 

 contract with the Division of Entomology) upon which he made 209 

 bales. In 1902 on the same place he had about 700 acres in native 

 cotton, but produced only 200 bales. This bears out the observation 

 referred to in another place that the improved varieties may be de- 

 pended upon to produce at least twice as much as the native plants 

 under similar conditions. 



A VARIETY TEST. 



In order to ascertain the comparative value of several of the differ- 

 ent varieties of cotton in avoiding damage by the boll weevil, eight 

 more or less well-known varieties were planted in plats of 5 acres each
