WHAT ARE THEY RUNNING THEM ON?

Threshing rigs

Pat enclosed a couple of pictures of one of the threshing rigs he used to own and the one most assuredly shows the smokestack is working! That's Pat posing picturesquely.

Along with my renewal to your magazine, I am also sending a few bricks in regard to some of the pictures in the ALBUM which show steam engines in operation with no tender and no visible supply of either fuel or water. What are they running them on anyway? Their reputation or compressed air??? -- It can't be the latter as there is no visible supply of air either.

I read some comments on a good threshing scene because there was no smoke from the engine. You can't burn coal in an engine without having some smoke. The best coal that was ever offered was Hocking valley because it produced the most heat units and it was identified by giving off the blackest smoke of any other grand of coal. Of course, if an engine smokes all the time, it denotes a poor fireman, but there has to be some smoke when the fire is replenished with fresh coal. That is why the upright pipe on the front end of a direct flue boiler or on the rear end of a return flue boiler is called a smokestack.

Yours for continued success and more realistic pictures of steam engines in action
