 cotton industry in the Salt River Val ley. In this regard. E. E. Mccall has this to say: Up to the time the Nc Call gins were opened and ready for operation. the cotton market here was virtually closed 10 outside buyers. The Mccall ginnin0 concern, however, with it's cooperative ginning plants recti fled this condition. did much to help the cotton industry in this sec ton"
 The Mccall ginning concern is es- sentially progressive and v0 to date, it's gin are equipped throughout with the most improved type of modern ma chinery. and are housed in sanitary, fireproof buildings of substantial con- struction.
 Many interesting experiments are hein~ carried on in the Mccall gins 10 better ginning conditions. a result of one Of these is the development at the Glendale plant of new type Of roller Co be used in the gin stand. which seems to be much more efficient than the old type made entirely Of walrus leather The new roller is covered. in- stead Of with a solid sheet of thick walrus hide. with alternate, concentriC strips Of walrus leather and packing. a combination Of rubber and canvas. This new type roller is said to grip the lint much better than the other type. Another interesting experiment in progress being carried on in the gin at ! Tempe is the introduction of a humidi- flyer in ginning operations. The hum idifyer is merely a device to introduce steam into the roller of the gin stand through a system of small jets. and causes the cotton to be ginned in an atmosphere made slightly humid by the steam. In short the humidifyer is ! designed 10 offset the lack of humidity ! in the atmosphere This humidity could not be supplied by water because l the pcr cent would not be constant. or ] if it could be made constant would not l be low enough. so it must be supplied | hy steam it is also well known that 1 cotton when it is too dry or too wet | does not gin to the maximum percent l age.
 At the Tempe gin it has been found that the breaking strength of cotton ginned under the humidifying process was much greater than that Of the same grade of cotton not subjected to the humidnyer. and that it makes much | silkier cotton result. The percentage of moisture cauysed by the humidifyer Co the cotton Is so small that the buy CTS do not object in the least
 Humidifying cotton has no effect on the capacity of the gin. but merely sup plies the small ~ercentage of moisture which is so beneficial to cotton caus- ing it Co lose it's brittleness, regain it's
 silkiness and maintain it's maximum
 strength of fiber A certain percent
 age of moisture in cotton is allowed by au buyers. but cotton shipped from
 dry climates such as Arizona. Egypt
 etc.. lack this percentage which would
 be of actual benefit to the cotton. lt
 is interesting 10 note that in Egypt this
 moisture percentage is supplied by
 slightly dampening the cotton as it is
 being packed for shipment after gin
 ming. This moisture gives the cotton
 added life which would otherwise be
 dry, hard and brittle
 Alr. Butterworth of the United States
 bureau of markets, during a recent
 trip into the valley visited the Tempe
 Ginning company gin 10 inspect the experiments being carried on with the
 humidifyer. He expressed himself as
 being impressed ond pleased with the
 results obtained Before leaving Mr Butterworth arranged for an actua test Co be made, and as result the gil is now ginning two bales of cotton al | hls request, one under humldfylnl
 conditions. and another of the sam,
 grade and quality of cotton without us
 ing the humidifyer. These bales vii
 be shipped 10 Washington where eX
 haustive tests and comparisons will b. made
 | In speaking of the humidifyer. thu
 idea of which B. E. Mccall brough here with him from the south. Mir. Me | ] Call recently stated that the cost O | this device was so small that if i | should prove successful. as MT. But
 terworth seemed 10 think, the othe
 gins of the valley would naturally fal | into line and install the humidifyeT
 thus ginning the entire cotton crop un
 der humidifying conditions and result | ing in a better product of cotton fo
 the entire Salt River Valley.
