been twisted over the guides to such an extent as to result in its assuming its present shape. The saw is twisted over twice.

Think what it means to force a wide Band Saw four inches out of a straight line between guides by setting out against it while returning for another cut. It is almost inconceivable that a saw could come out of such a severe trial unbroken, but this one did, as the most careful inspection failed to disclose a crack, and the braze, although badly bent and distorted, was still intact.

This saw was originally 12 inches wide, but had been in service for several months on one of the finest mills in the country which worked it up to its fullest capacity. Beside giving excellent service the accident proved it to be an article of the highest quality, possessing the greatest tensile strength, high tough temper, tension, and edge holding qualities, all of which combine to make the highest grade Band Saw. It proved a perfect example of what a DISSTON BAND SAW is capable of. The great care exercised throughout every operation during their making, from the melting of the steel in the crucible to completion, never relaxes. "Quality Tells", and quality is an inherent part of all DISSTON BRAND GOODS.

plug has been driven in, and attached to this is a stationary arm of wood from which a movable lever arm is attached to one end of a narrow cross-cut saw. On the other end of the saw is an old fashioned tab and handle. You will also notice the material on the buck is a railroad tie, which, judging from the amount of fire wood piled up around the shacks was cut very readily with this outfit. Quite possible the idea was imported from Italy as I never saw anything like it in this section of the country before."

In February Mr. Ernst Säumenicht will leave for South America where he will look after the interests of HENRY DISSTON & SONS. This is made necessary because of the continued growth of their business in that country, due to increasing importance of the lumber industry.

Mr. Säumenicht will be gone about two years, during which time he will visit Brazil, the Argentine, Chili and Uruguay. Readers of "The Crucible" will be interested in learning that he carries a camera, and we have arranged to have him furnish this little magazine with a number of pictures showing mill operations in South America.

The center spread this month (pages 8-9) show the filing room and plant of the St. Maries Lumber Company. This is considered one of the most up-to-date mills in the "Inland Empire", and for that reason will be especially interesting to millmen in the lumber regions of the East and West coasts.

The mill was designed and built quite recently by Mr. W. D. Starbird for Mr. William Kroll and his associates. Mr. Kroll is now General Manager, Mr. Baker, Secretary and Treasurer. It is equipped with two

bolt imbedded in it was cut by a DISSTON Band Saw running at the rate of about 10,000 feet per minute. Mr. Ricker states that he looked the saw over carefully after it made the cut and found that it was not injured. The tension remained perfect, and none of the teeth which came into contact with the bolt were injured in any way except the stripping of part of the swedging. This was stripped off of 20 teeth. One swedging put it back again.

Mr. Ricker, and Mr. Fuller, the mill Superintendent, say that in all their

8-foot band mills, using 13-inch, single cut DISSTON SAWS, and is practically electrically driven. The mill is situated on the St. Joe River, about one mile from the town of St. Maries, Idaho.

Almost the entire cut of the mill is white pine and they have a daily capacity of about 230,000 feet for twenty hours.

The photograph of the filing room shows Mr. Jerry Ricker, the filer, at the bench, and Mr. Hill, his head helper.

We are indebted to Mr. Ricker for the slab of Western white pine shown on this page. The 5%-inch drift

years of experience as millmen, they have yet to see a saw other than a DISSTON that could make such a showing.

Their faith in DISSTON SAWS is shown by the fact that this mill is completely equipped with them.

CISSTON

The efficiency of the DISSTON Saw is more easily maintained by the use of the DISSTON File.

D

With the very small sizes of files it is necessary to straighten them after the teeth are cut. This is done by the use of a lignum vitae block and a lead hammer, which straightens the file, but has no effect on the teeth.

The file is then covered with a paste that protects the edges of the teeth during the hardening process, which is one of the most important operations. After being hardened, and while the file is still hot, it is put through a final straightening process. After this, comes the "scrubbing' and "drying. The first of these operations removes from the file the paste that was put on to protect the teeth during hardening. In the second, the files

are washed in lime water and are dried by holding them in steam.

The next and last operations in the making of a file before the final inspection, "blueing

the

the tangs, and oiling the file. This "blueing" operation toughens the tang against breakage when putting the handle on.

The method of manufacture differs slightly after the grinding operations. The superfine file is put through a "shaping" process which corresponds in effect to the "stripping" operation in the case of the larger files.

To do this the file blank is secured in a vise, and the soft surface (the blank not having been hardened as (Continued on page 16)
