ing a driving-wheel, and that would, by means of the wires, convey a crank 

 motion from the wiiulinill to the churn, no matter how distant ; and tlie 

 motion can be stopped and started as easily as tliougli churning by Iiand. 



The objection to wind-power is want of constancy. Tliis can only be 

 obviated by accumulating power. If the situation is such that a water 

 reservoir can be tilled upon high ground, to be used in a calm, the accumu- 

 lation of power would not be expensive. 



The method of convx^j-ing power by wires a long distance, from the water- 

 wheel to the churn, may be seen in several places along the Chenango Canal. 



370. Self-regulating Windmills.— One of the best contrivances for a self- 

 regulating windmill was invented by Daniel Ilalliday, of Ellington, Tolland 

 Co., Ct. The size mostly built by him has five-feet wings, that is, the diam- 

 eter of the wind-wheel is ten feet, and the first one was in operation for six 

 months without a hand being touched to it to regulate the sails. It run 

 fifteen days at one time without stopping day or night, and it stood through 

 some hard gales. The beauty of the improvement is, that it stands still when 

 the wind rages hardest, with the edge of the wings to the wind, and as it 

 lulls they gradually resume their position for a gentle breeze. It is so con- 

 trived that nothing but a squall of great severity falling upon it without a 

 moment's warning can produce damage. 



Tlie mill mentioned has drawn water from a well 28 feet deep, 100 feet 

 distant, and forced it into a small reservoir in the upper part of the barn, 

 sufficient for all farm purposes, garden irrigation, and " lots to spare." The 

 cost of such a mill will be $50, and the pumps and pipes about $25. It is 

 elevated on a single oak post a foot square, the turn circle being supported 

 by iron braces. The wings are made of one longitudinal iron bar, through 

 which run small rods ; upon these rods, narrow Tjoards, half an inch thick, 

 are fitted, holes being bored through from edge to edge, and screwed 

 together by nuts on the ends of the rods. Tliis makes strong, light sails, 

 which, it wiU be seen, are fixtures not to be furled or clewed up ; but they 

 are thrown up edgewise to the wind by a very ingenious and simple arrange- 

 ment of the machinery, which obviates the great objection to windmills for 

 farm use — the necessity of constant su" ervision of the sails to suit the 

 strength of the wind. 



With this much food for reflection, we will close the chapter upon the 

 farmery.
