Windmill. 531 



WINDMILL. 



If we except horse-power and that of cattle there is no 

 form of motor which has been so generally or so widely 

 used on the farm as the windmill and its use is daily in- 

 creasing, especially now since all parts are made of steel 

 well galvanized to protect them from rust, and their rela- 

 tive efficiency has been increased. 



667. Work to Which the Windmill Is Adapted. It must 

 not be understood that a windmill is well suited to furnish 

 power for any and all kinds of farm work if only it is 

 made large enough. On the contrary it is only adapted 

 to certain lines where the work done can be accumulated 

 at times when the wind is favorable. 



The windmill is peculiarly well adapted to pumping 

 water for stock and for the supply of the house if only a 

 suitably placed reservoir of sufficient capacity is provided. 

 It must be remembered, however, that in many localities 

 there may be periods of calm of three or even occasionally 

 of seven days' duration when there will not be wind enough 

 to permit the mill to do any work. 



For grinding grain fo*r farm stock the windmill is pecu- 

 liarly well suited, provided arrangements are made so that 

 the grinder is automatically fed and the meal allowed to 

 drop into a bin where it may accumulate without personal 

 attention. Arrangements of this sort may easily be made 

 but it requires a special form of grinder which is not only 

 automatic in its feed, but in the rate at which it feeds as 

 well, supplying the mill heavily when the wind is strong 

 and leaving the burrs empty whenever the wind falls so 

 that no work can be done. 



Where an abundance of water is available, with a lift of 

 only 10 to 20 feet, the windmill may be used to advantage 

 in irrigating small areas of two to five acres, but in such 

 cases it will usually be necessary to provide a reservoir of 

 suitable size into which the water may be pumped and 

 stored.
