to make up a bale." "Do the natives of India take the seeds out of their own cotton?" asked Mary. "Some of them do, using the primitive gins so long known in India. The Chinese also gin much of their own cotton by amateur gins. But it goes without saying that much of the cotton fiber is broken by these methods. For the more perfect the gin the less loss results. Even with our best machinery however, a certain amount of injury is done which cannot be avoided." "Then Eli Whitney's gin isn't so perfect," ventured Carl. "Its method is as perfect a one as we have," answered Captain Dillingham, "and up to date nothing better has been found. Those handling large quantities of cotton are almighty thankful to have anything as good, I can tell you. In India, China, and oriental countries, though, where the lots are small the people, as I say, still cling to their primitive foot gins. Here in America we have several types of gin all made on the same general principle but differing slightly as to detail. Some of these are better than others. By this I mean some are less brutal and cause a smaller degree of waste. Indeed I believe Whitney's own gin and those of its kind known as saw gins are considered to do the most damage to the fiber. This sort of gin consists of a series of circular saws set into a revolving shaft in such a way that the cotton fed into the machine is separated from its seeds in an incredibly short space of time. Afterward a whirling brush cleans the saws of the fiber clinging to them. It is an effectual system but a merciless one and is best adapted to short staple cotton which is strong and does not snarl. The best gins use only long, smooth blades to clear the cotton and it follows that these do the fiber far less injury." "How does a ginning factory look, Uncle Frederick?" Carl inquired. "You mean the inside? I never went through but one. I was waiting for a cargo at Norfolk once and as there happened to be a ginning plant near where I was staying I visited it. Generally peaking I suppose they are pretty much alike. The cotton is brought to them, as I said, in clearly marked, or branded bags or baskets, and is tossed from the wagons directly into hoppers. Afterward the contents of the hoppers is loaded into freight elevators and shot to one of the upper stories of the factory, there to be piled up and await its turn for ginning. "When the time comes to gin that particular batch it is heaped in
