hour. My mill grinds all kinds of feed, fine or coarse, and cornmeal 
Graham flour for table use. We cut our cornstalks with a big fodder cutter 
All of these machines are run on the west barn floor, which necessitated puttins 
up 44 feet of horizontal shafting. : 
Another farmer, living in Ohio, describes in the Rural New Yorker ™ 
detail the method of fixing up windmills on barns. There are many ways; he 
says, of putting a windmill on a barn, and each barn frame will suggest } 
different plan. Fig. 1 shows how we did at Woodside Farm. The mast, B,

just a little below the level of the “square,” as in most old-fashioned barns 
From the tie to the comb of the roof at C is 15 fect. FF F are rafters. EI 
apiece of 6 inches by 6 inches let in between the ends of the rafters. To put iti 
we first nailed strips of board across from one rafter to the other, as shown at 0 
Then the ends of the rafters were sawn off, 3 inches from each, so that the 6 inches 
by 6 inches stick would just drop into the notch. It was put in place, and the 
rafters nailed firmly to it when the temporary supports were knocked off. The 
brace, D, is also 6 iuches by 6 inches, and firmly bolted at each end with two 25° 
inch bolts. This bolting is necessary, because the brace must hold from gone 
out as well as coming in, At C,a strap of iron passes around the mast, 4” 
bolts firmly to the horizontal piece, E.

arranged as in most barns. On one of them rests the foot of the brace, »- 
This brace, too, is firmly bolted at bottom and top. It would have been # 
well to have used two of these braces, one on each side; but I did not do it, 
partly because I did not care to have so many places to make watertight 10 the 
roof. Do not fail to make this mast solid and safe. It will be a satisfaction to 
have it so when you go up to oil, and the wind is blowing a gale. Speaking ° 
oil, do not forget that the life and much of the efficiency of the mill a0 
machinery will depend on keeping it oiled. What would you think of an 
engineer who would oil only once a week? An aermotor runs very rap! f 
being geared high, and should be oiled before each full day’s work, oftenet 3 
you are an enthusiast on the subject of taking care of machinery. For moder 
work and light winds and common pumping, I find once a week often enoug™ 
For a 12-feet aermotor let these braces reach to within 43 feet of the 
of the mast. The centre of the wheel will be above the top. Let the mast ?° 
full 8 inches by 8 inches in size. Another plan is applicable to barns where 
mill is wanted near the centre. It has been tried by some of my neighbours | 
It works well. The mast is set on the purlin plate, and extends as far through 
the roof as is desired, 20 feet being a good height, and is stayed by four W 
cables, one reaching to each corner post of the barn. ‘These cables are ™ 
right on the spot of common galvanised fence wire, No. 9, six strands beins 
used. These wires are first put up and stretched tolerably tight, when they a 
twisted by putting in a stick and twisting. Care is used to tighten each CH 
alike, so that the mast will stand perpendicularly. This is even a safer wi 
than mine, as the cables run quite obliquely, and are of immense strength. 
would take about four tons’ pull to break one of them. ;
