THE INDIA RUBBER WORLD 



[June 1, 1919 



The average yield ot cotton in Arizona has been about half a 

 bale to the acre but some farmers recently have done much bet- 

 ter, it is said. It has been demonstrated that new lands are not 

 as good for cotton as the older lands on which there has been

alfalfa or Bermuda. Overirrigation has been responsible for 

 more poor yields than lack of water. Rotation of crops has 

 been found to be efficacious in increasing the yield, preferably 

 every three years, when alfalfa is produced. There have been 

 serious delays in the ginning, caused by lack of machinery, or- 

 dered but not received in time. Some of the gins have been 

 doubled in capacity and have been kept working at top speed. 

 The picking for this year was about completed in March, ac- 

 cording to the latest figures from Phoenix. 



While cotton is most valuable for its use in staple manufac- 

 tured goods, its utility in by-products is worthy of attention. 

 After having gone through the gin, and a certain percentage has 

 been disposed of for seed and the remainder crushed for oil, its 

 mission in life is by no means ended. From the seed are ob- 

 tained linters, hulls and the meats or kernels proper. The lin- 

 ter is merely the layer of short lint which thoroughly covers 

 the seed pod. It may be used for upholstery, absorbent cotton, 

 felt, cellulose, twine, gun-cotton, writing paper, varnishes, etc. 

 The hulls are used in bran, fertilizer, fuel, packing material, fiber, 

 stuffing for horse collars, bases for explosives and pressed paper 

 products. 



The usefulness of the meats or kernels of the cotton seed 

 naturally exceeds that of the linters and the hulls. Two products 

 are made from the kernels, cake or meal and crude oil. The 

 first product finds its usefulness in dyestuffs, fertilizers, flours 

 and in an unusually well-balanced feed for cattle and other stock. 

 The crude oil goes through several refining processes, yielding 

 oils of various qualities, many of which are useful as foods. 

 The so-called foots, produced from the crude oil, are used in 

 washing powders, soaps, glycerine, candle pitch, composition 

 roofing, linoleums, insulating material, oilcloth, waterproofing, 

 artificial leather and phonograph records. 



California claims to be far ahead of Arizona in acreage and 

 general expectations. It is declared ihat the following figures 

 show what is to be expected from California: Imperial valley, 

 142,000 acres ; San Joaquin valley, 35,000 acres ; Palo Verde valley, 

 23,000 acres; Bard district, 1,000 acres; miscellaneous areas, 1,000 

 acres. Tlie farmers of the San Joaquin valley are especially en- 

 thusiastic over the outlook this year and are planning to increase 

 their acreage greatly. There is some conflict of opinion in this 

 district as to the best varieties to plant, it is said. Efforts to 

 exclude by legislation all varieties of cotton except Pima or 

 Yuma Egyptian strains have not been entirely successful. Some 

 growers who preferred the short staple have made a successful 

 effort to have their way. It is said the first experiment in rais- 

 ing cotton in the San Joaquin was made 35 years ago. There 

 was a considerable acreage also in the early 'eighties when a 

 large force of men was employed to gather it. A strike over 

 some minor matter took place, and the superintendent, a man 

 of choleric disposition, rather than yield or compromise with 

 the strikers, set the field on fire, thus ending for the time being 

 what might have developed into a big industry. 



Favorable factors in prognosticating returns from cotton rais- 

 ing this year are: (1) decrease in cotton production as a whole, 

 both in the United States and elsewhere in the last few years; 

 (2) increase in the number of cotton spindles in the United 

 States and England; (3) new uses for cotton and cottonseed prod- 

 ucts. 



Limiting factors in normal cotton consumption are (1) time 

 needed to restore the wrecked mills of Belgium and France, 

 and to reorganize the cotton-spinning industries of Germany and 

 Austria; and (2) time for the impoverished peoples of Europe 

 to recover their normal buying power. Prices, because of the 

 fact that cotton is a basic commodity, probably will not be low- 

 ered appreciably except in proportion to labor and living costs. 



The estimate of the Department of Agriculture is a carry-over 

 of 3,000,000 bales, about as much as there was last year. The 

 growers express the greatest faith in the recuperative powers of 

 mankind and declare that the world will actually need more than 

 the United States will have to sell this year. 



PIMA COTTON IN ARIZONA. 



Edward F. Parker, vice-president of the Southwest Cotton Co., 

 Phoenix, Arizona, states that there will be about 350,000 acres 

 under cultivation in the Salt River valley this year. Of this total 

 about 80,000 acres will be in Pima cotton, some 10,000 acres be- 

 longing to the Southwest company. 



It has been found impractical to grow this grade of cotton on 

 all of the irrigated land of this valley because some of the land 

 is not suited to the crop. In order to compete successfully with 

 Egypt and other sources of cotton of similar quality, it is desir- 

 able to rotate with alfalfa and keep the land in the best possible 

 condition so that it will yield to maximum capacity. It costs no 

 more, and often less, to grow a large crop on a small acreage 

 than to grow a small crop on a large acreage. The real profit 

 is in the yield which is in excess of the average. 



Mr. Parker has recently been made president of the Salt River 

 Valley Hotel Co., Phoenix, Arizona, which is planning the erec- 

 tion of a handsome tourist hotel to be called "The Arizona." 

 Associated with him in the enterprise are a number of important 

 business men in Phoenix. 



REDMANOL. 



Redmanol is a synthetic resin or amber made of phenol and 

 anhydrous hexamethylene-tetramine, possessing unusually high 

 dielectric strength, exceptional heat-resisting qualities, brilliancy 

 and luster, and great chemical inertness. With the proper fillers 

 it withstands a temperature of SOO degrees F. in the air, and 650 

 degrees F. in live steam or boiling oil, without changing its shape 

 or characteristics of chemical inertness. It may be used in 

 making the type of articles known as condensation products.
