The Characteristics of a
Good Engine

First of all, it should be simple, both in design and construction; so simple that anybody can understand it, and so simple that it is almost impossible for it to get out of order.

Again, it must be safe, economical in fuel consumption, absolutely dependable under all conditions, and certain of supplying abundant

power.

I.H.C. Gasoline Engines

have all these characteristics, besides another
very important one. which most engines do
not possess, that is, they are

THOROUGHLY ADAPTABLE TO THE WORK IN HAND

No matter how excellent a power may be, if it is not adapted to your particular requirements, you do not want it. The designers of I. H. C. engines kept uppermost the purposes to which such an engine could be adapted, and constructed the engine with a view of meeting every requirement.

The line is extensive, and an I. H. C. agent will always recommend the engine which is best adapted to your requirements.

Made in the following styles and sizes:

Vertical in 2 and 3-horse power.

Horizontal (Stationary and Portable) in 4, 6, 8, 10, 12, 15 and 20-horse power. 1-horse air-cooled. Also, sawing, spraying and pumping outfits. Apply to the International local agent for catalog and particulars, or write
