 The modern cotton gin is device for separating the seed from the lint or as the little English expert who visited this valley two years ago put it. Ginning is the art of getting rid of the seed yb know" A ginning plant consists of seed cotton (cotton as it comes from the field) store houses, equipment for handling the seed cot ton. cleaners, gins, cotton press, seed cleaners, warehouses for storing the seed and yard room for storing the haled lint
 The sin that is used on the Salt River valley cotton is the roller or knife gin The machines that are used here are made in lcngland ard are the same as those used in Egypt and in the Sea Island cotton lands on the Atlantic coast. Az compared with the saw gins used in the short staple cot ton countries they are much slower in their operation but do mol hurt the Aint. For this reason they have to be used on this Arizona Egyptian long staple cotton.
 When the cotton is brought in to the gin it is taken off the wagons by suction and either stored for future sinning or is taken directly on to the gin floor and the operation of ginning is started. One of the most vital things in the handling of this cotton is Go get it clean-in other words get all of the trash possible out of the seed cotton as it comes from the field. At the sin in Tempe the cotton is run over two vacuum cleaners and another mechanical feeder anc cleaner When the cotton is absolutely bone dry we are able to get out the biggest part of the trash and of course this enhances he value greatly of the finished product.
 When the cotton leaves the vacuum cleaner it is distributed by means of a spiked belt Co pockets above each gin stand. From here it is fed into the sin through the mechanical cleaner and the last of the dirt that it is possi- ble 10 take out is removed here. It is fed into the gin, a small quantity at a lime and the gins are allowed to re- move the seed and then another feed is put In and so on until the compile ton Of a bale. Eath mans cotton is kept entirely separate from each other mans
 The roll of the gin as it receives the seed cotton catches the lint and pulls lt under the stationary knife while the moving knife strips the seed from each lot, the lint passing over behind the machine to be gathered up and trans erred to the press. This roll is GOV cred with walrus hide which at this iiAe is one of the many very expensive materials used in cotton ginning.
 The seed as it Is separated from the lint drops into an auger below the gin and is transferred to the elevator which carries it into the seed cleaner where the locks that have not been ginned in the first process are separated rom the seed and by means of the suction are carried back to the gins and tine process completed The seed that passes through the cleaner are gathered and elevated again to the seed auger that goes to the seed stor- age house and is there stored for planting or mill purposes as the case may be
 The lint as it falls back of the gins is gathered up by means of folks and moved down to the hydraulic press where it is formed into the bale which is wrapped with burlap. bound with
