ARIZONA COTTON |S PEER IF ANY
 IN WORLD
Government Tests Prove Conciusively
 That Long Staple Has Great Future

WASHINGTON, April s. Because of the marked increase in the pro- duction of the Arizona-Egyptian cot ton. cotton technologists of the United States department of agriculture have been conducting spinning tests to com pare it in waste, tensile strength, bleaching, mercerization, dyeing and finishing qualities with Sakellaridis Egyptian and Sea Island cottons.
 The tests thus reported were con- ducted on the 1914 crop during the summer of 1915 on the following lots Of cotton, namely, four bales of Ari- zona-Egyptian cotton, one of each of the grades, extra, choice, standard, and medium; three bales of Sakellar- idis Egyptian cotton, shipped from Alexandria, Egypt, of the grades good, fully good fair, and fair; and two bales of Sea Island cotton shipped from Blackshear, Ga, of the grades fancy, and extra choice.
 Throughout the test care was taken to have mechanical and other condi- tions the same for each kind of cot ton.
 The relative waste discarded in the manufacturing processes of the four
 
 tested was as follows; extra, IT 89 per cent; choice, 1856 per cent; stan dard, 20 per cent; medium, 20.90 per cent.
 These tests show that with respect to grade. the four bales of Arizona Egyptian cotton were approximately less wasty than the two bales of Sea- Island of Georgia, and the two bales of Sea Island were approximately less wasty than the three bales of Sak- eliaridis from Egypt.
 There was no relation in the price of the different kinds of cotton to the percentages of waste discarded in the manufacturing processes.
 There was no significant relation ship between the tensile strength of the respective grades of Arizona Egyptian cotton.
 The difference in the tensile strength of yarn made from the three kinds of cotton was practically negli- gible Considerable deviation occurred varying slightly in favor of first one kind and then another.
 There is no significant relationship between the prices of the different cottons and the percentaee of waste and tensile strength. The results show that our domestic cottons are equal to, and in most respects super for to imported cottons The prefer ences of manufacturers must be changed in order to introduce satisfac torily any new cotton.
 The laboratory test indicated that after bleaching, dyeing and mer cerizing, the Arizona Egyptian and Sea Island cottons were practically equal to each other and were slightly bleaching and merceriZing properties that they were fully equal to each other in dyeing properties;- and in tensile strength the advantage was slightly in favor of the Sea Island and Sakellaridis.
 In regard to introducing newsva riety of cotton, the authors say in the bulletin:
 Manufacturers who have expert mented with the Arizona Egyptian cot ton have found that it is less wasty than other cottons and that it can be utilized satisfactorily as a substitute for most purposes Because the Ari zona-Egyptian is heavy bodied cot ton, it is entirely possible that the entire amount produced can be util ized advantageously if mixed prop ierly with these other cottons in the manufacturing processes. Manufactu rers claim that the sooner this cottor comes on the market in large quanti ties, the easier will it be to place il in a competitive basis with other Ions lstaple cottons of similar qualities.
