In planning the first equipment of the Ann Arbor Central Mills, we aimed to secure a complete outfit for doing all kinds of farmer's work in our line. As time has passed, many improvements have been invented which have been introduced into our mili. The latest of these is a power cleaning machine, designed to replace the farmer's fanningmill. It is the first to be placed in any mili in this part of Michigan, but we have put it in operation only after thoroughly satisfying ourselves that the machinery has proved a marked success in many parts of the country. The entire working of the machine is open to the inspection of all farmers. It cleans wheat exactly as a fanning mili does the work only with less waste of good grain and very much more rapidly,its capacity being 400 bushels per hour. All screenings are run into the farmer's bags to be ground for feed or taken home by him, as he sees fit. This machine is now ready, without charge for its use, for those who wish to avail themselves of it.
