natural resources have been exhausted the windmill will

still remain, and will probably furnish 
light, heat and power for the remnant of the human race. In the interim, between the beginning 
and the end (where we now are) it makes a greater return to the people in proportion to its 
cost than any other machine. It does more cheaply, and with less attention, the thing 
which it is fitted to do, than any other power. 
The wind blows everywhere and is free. With a windmill, the expense 
for oil and repairs is the only 6ne, and that is trifling. An engine requires 
much more in the way of oil and repairs, and fuel — which is the great expense 
— has to be added. 
The windmill does not require an experienced man to operate it. It is so simple 
that anyone can understand its workings. 
A well-made windmill is a durable machine. The driving shaft of a windmill runs 
only about one-fifth as fast as the crank shaft of an engine of the same power. A good 
windmill will outlast several engines doing the sa ne amount of work. 
The best farmers, everywhere, use windmills generally for pumping water. In every 
progressive farming community the windmill is the most conspicuous object. It towers above most 
‘groups of farm buildings. 
All the world knows that the Aermotor Company made the first steel windmills 
and steel towers, and made the steel windmill and steel tower business. It is believed that, 
since the business was fairly established, it has made, and continues to make, more than half 
the world s supply of windmills. In the Aermotor the plan of back-gearing was first introduced 
into windmill construction. By this means the power of the swiftly running wheel is utilized 
without operating the pump too fast. 
The peculiar form of Aermotor wheel, which gives it great power, also enables 
it to run in the lightest breeze. No windmill has yet been made which equals the Aermotor in 
its light-running qualities. The form of the wheel is exactly right. 
Simplicity is another of the important features of the Aermotor. There are no complicated parts to get out of order, 
skillful adjustment. Every part is solid, substantial and durable. 
There are no devices requiring

I he main bearings of the Aermotor have large dust-proof oil pockets which afford the best possible means of lubrication, 
automatic oil cups. 
Aermotor has thoroughly demonstrated its Staying qualities. In almost any community Aermotors can be found 
which have been doing duty for fifteen, eighteen or twenty years. And these old Aermotors were made before the days of the heavy gears and the 
shaft-carrying arms which are easily turned in their sockets so as to give new and perfect bearings for the shafts in case they have become worn through 
overloading or neglect. The present Aermotors are sure to be more durable and serviceable than the earlier ones. 
The galvanizing of Aermotor outfits has had much to do with their popularity. Aermotor galvanizing is real 
galvanizing. It is the best that can be done and will last a lifetime. Aermotors which were 
galvanized twenty years ago are as good as ever. Stni 
The Aermotor Company has been building for the ages. It has always been working ZC S Smiling 
toward the building up of a great and permanent business. It has succeeded so well that Aermotors are as well 
known in South America and South Africa as in the United States. Dealers in Aermotor goods are found every¬ 
where. When you want anything in the Aermotor line you can get it and get it quickly. 
AERMOTOR PRICES AND POLICIES 
When the Aermotor Company commenced the manufacture of the windmill, it reduced the 
cost of wind power to one-sixth of what it had been. It advertised its prices. It made the best 
thing that could be made and at the lowest price at which it could be made. It uses no traveling 
men. It made so good an article that one-half the world’s business came to it and stayed with it. 
It is doing the same thing with the gasoline engine. Where one goes others follow, and we are 
turning them out in great quantities, to the delight of Aermotor friends everywhere. We could send smart traveling salesmen to see you and 
persuade you to pay $25 or $50 more for a windmill or an engine, and it would be worth it—not to you, but to us. But there are plenty of 
reading and thinking men who prefer to save their own time and money and deal in the Aermotor way. 
AERMOTOR GASOLINE ENGINES 
Wherever a Windmill is suitable for the work, an Aermotor furnishes the cheapest and most satisfactory power for pumping. But there are 
some places where a good wind exposure cannot be had. There are other places where power is wanted only temporarily. Sometimes tenants are obliged to 
supply their own power for operating the pump and do not wish to put up a windmill which they will have to leave behind them when they move. To supply 
the demand for a pumping power for such cases the Aermotor Company makes a gasoline engine which can be attached to “any old 
pump ” in thirty minutes. It is sold complete and ready to connect to the pump for $37.50, F. O. B. Chicago. 
For ranch purposes, or for handling large quantities of water, a heavy, back-geared pumping engine is supplied 
for $ 100 . 00 , all complete, ready to receive the well fittings, which can be set up in working order within an hour after it is 
received. It is capable of raising sixty barrels of water an hour to an elevation of one hundred feet. 
For running machinery, the Aermotor Company makes a line of General Purpose Power Engines. The 2 H. P. 
Hopper Cooled Engine sells for $75.00, 4 H. P., $125.00. All prices are F. O. B. Chicago. 
These engines are fitted with the Aermotor galvanized steel pulleys. Who ever heard of a galvanized 
steel pulley? No one. Nor did anyone ever hear of a galvanized steel windmill, or steel tower, until the Aermotor Company pro¬ 
duced them. These galvanized pulleys are sure to revolutionize the pulley business. They are light, strong, cannot be broken and 
are wonderfully cheap. A complete set of seven pulleys for a 2 H. P. engine is sold for only $8.00. A set of seven’pul- 
leys for the 4 H. P. engine sells for $11-90* We always furnish one pulley free with 
each power engine; but to anyone thinking of buying an engine, who writes us within one 
week from the appearance of ihis advertisement, stating in what paper he saw it, we will 
furnish free, with each 2 H. P. engine or larger, $5.00 worth of pulleys of any size which 
you may select for either engine or line shaft, provided the order is sent in before January 
1st, 1912. Pulleys for the line shaft — being used where they are protected from the 
weather — are not galvanized.

MAGNETO FREE 
All Aermotor Power Engines are fitted with a magneto 
free. Batteries are not used with these engines. You have no 
ignition troubles when you buy Aermotor Gasoline Engines fitted 
with the Aermotor magneto. We don’t believe that anyone 
who once sees an Aermotor Engine run with magneto will take 
any other engine as a gift. For full particulars write
