THOMAS STEBRITZ of 1516 E. Commercial St., Algona, Iowa 50511 wrote a nice long letter with some great pictures, after reading a recent issue:

'The March/April IMA was fairly interesting, and I will touch on a few articles and letters. About the 'advice for boiler buyers,' if you find an engine and want a good opinion on the shape of the boiler, find a person to look it over with all the plates and plugs removed. This person should be a person who can see what he sees, certainly not a boiler inspector, who would be a hostile witness.

'Did you ever wonder why some boiler inspectors maybe have a mean look? One reason might be some of the patched up junk some people want them to inspect. However, the most important reason is that most all of the farm engines in the United States were not inspected, then along comes a little item called a thresher reunion, then suddenly a lot of inspectors had to crawl into some dirty cramped fireboxes, and sometimes got a bath tapping on firebox sides.

'All of a sudden the inspectors had hundreds of boilers to inspect and still do, being out in the public think about that.

'The term ultrasound is used more and more. After you have satisfied your boiler's interior is sound, what is the shape of your firebox sides and crown sheet around the stay bolt heads? The stay bolt heads are insulation and in a lot of fireboxes the fire and heat circulating around the stay bolts eventually burns a fire ring around a lot of stay bolts, especially of those in the crown sheet, and burns the flange off the stay bolt head.
