WIND-MILLS FOR FARM USE. 



Geo, E. Waring said that farmers would find wind-mills very 

 valuable and economical power. He looks upon them as very 

 valuable in draining land. He thinks a swamp of a dozen 

 acres, with a wind-mill of three horse power, could be kept per- 

 fectly dry. 



Dr. Johnson explained the model of his patent wind-mill, 

 which was on exhibition in the club room. 



Mr. Brown had a working model of his mill also present, which 

 he explained. It is regulated by weights by centrifugal force; 

 the faster the fans circulate, the more they turn the edge to the 

 wind. Brown's mill is a good machine, and is known as the 

 Vermont wind-mill. Our friends, Fowlers & Wells, have some- 

 thing to do with it, and can give information. There are ten 

 sizes, costing from $50 to $350. Farmers and others in want of 

 a cheap motive power should look to the inducements offered of 

 putting up a wind-mill on their premises. It may be very econo- 

 mically used to pump water for draining or irrigating land, 

 household use, or for supplying railroad stations, for which it is 

 especially adapted. For irrigation alone there are hundreds of 

 situations where the mill would pay for itself in a single season. 

 It may be used, and will give good satisfaction, to thresh, win- 

 now, shell, or grind all kinds of grains, peas, beans, and to grind, 

 cut, or mash apples, roots, paints, &c. These mills may be at- 

 tached to a barn, or other building, or placed up a tower erected 

 for the purpose. 



Judge Meigs again suggested that in clearing land, a tree might 

 be left for this purpose. It would be very solid and strong, and 

 last many years. The model of Johnson's mill shows a good deal 

 of ingenuity, and he thinks is so regulated that it will withstand 

 a sudden squall, as the fans open by pressure of the wind as well 

 as by the increased speed. It was understood, however, that it 

 had not been practically tested upon a large scale, 



halliday's wind-mill, 



Solon Robinson said the patentee of the mill known as Halli- 

 day's wind-mill is entitled to credit as the pioneer of improve- 

 ments. He first produced a perfect self-regulating wind-mill,
