selection should be repeated from year to year, and no inferior cotton 

 planted near enough to vitiate the chosen variety with its i)ollen. In 

 these experiments the strongest fiber was produced h^ the Truitt 

 variety ; the largest by Barnett ; the smallest by No. 1 Hawiiins' Im- 

 proved, and Peterkin ; the longest by Okra Leaf; the shortest by No. 2 ; 

 and the best twisted by Truitt, Eameses, and Cherry's Cluster. 



The largest percentage of fiber per boll was produced by Welborn's Pet, Okra Leaf, 

 Peterkin, Hawkins' Improved, King's Improved, and in the order uaraed. The 

 largest percentage of seed per boll was produced by Zellner, Rameses, Southern 

 Hope, Truitt, and in the order named. The best grade of cotton, taking all things 

 into consideration, is Cherry's Cluster. ■ The second best grade is Truitt.

Experiments to test the possibility of developing a do- 

 mestic SUGAR industry, A, T. Neale, Ph. D. (pp. 3-11).— In the 

 crop rotations followed in the Northern Atlantic States for nearly a 

 century, Indian corn has been commonly grown once in every four or 

 five years. The low price of corn has of late created a demand for a 

 substitute crop similar to corn in its habits of growth and in its de- 

 mands on the soil. The products of this crop should also, as in the 

 case of corn, be able to endure transportation and storage, and be used 

 for daily consumption in every family. " Sorghum is the only plant 

 which either fulfills or can be made to fulfill all of the above conditions. 

 Its leading product should be refined sugar." 



The problems relating to sorghum are discussed in this bulletin from 

 the standpoints of the sugar boiler and the farmer. The author speaks 

 from several years' experience in New Jersey in connection with inves- 

 tigations on the field culture and chemical composition of sorghum, 

 and on the manufacture of sugar from this plant. After seven or eight 

 years of hard work and bitter disappointments, the sugar men can now 

 justly claim to be able to extract, commercially and economically, 90 

 per cent of all the sugar present in the cane. The product up to this 

 point will be a heavy sirup. If the cane is of good quality 75 per cent 

 of the sugar in this sirup can be delivered to sugar refiners in the form 

 of old-fashioned, heavy brown sugar. The other 25 per cent will remain 

 as a low 'grade molasses, worth at wholesale, at present, about 20 cents 

 per gallon. 



" If, however, the cane delivered by the farmer is of low grade, then 

 the sugar men can only guarantee to waste not more than 15 pounds, 

 of sugar in each ton of field sorghum ; their product will be sirup only, 

 for, from such stock, they will be unable to extract with profit even low 

 grade refining sugar. 



"In explanation of the terms low grade and high grade sorghum, it 

 may be stated that if all of the water in cane juice is boiled away, a 

 mixture of sugar and of foreign matter will remain. If out of 100 

 pounds of this mixture from GG to 75 pounds is sugar, then cane yield-
