AUTOBIOGRAPHY
Paul, as assistant engineer. The Dells Improvement Company
hired C. M. Buffington to look after the work-not only the
work of building the dam, but the building of the piers, the
buying of material, and looking after the quarrying of stone
for piers and filling in the crib work. On my return from a
trip in the woods, on a very cold day, I went into the building
put up by the contractor, Mr. McIntyre, on the east bank of
the river, near the end of the dam, where they had one or two
stoves to make it comfortable for the men who were getting
out patterns, and doing other work they had to do in the shop.
I found Johnson and Buffington sitting by the stoves, warming
themselves. I asked how they were getting on with the work,
and they answered first-rate. I told them I was going down
to see how it looked to me. The crib work was made of timber,
with an apron below the dam; and the rock was cleaned off
perfectly level. The specifications required 12x12 pine timber,
32 feet long, running up and down stream from the foot of the
dam, down, to be held to the flat surface of the rock with inch
and a quarter round bolts, 30 inches long, holes drilled in the
rock, and the bolts with upset heads. The bolts were split
about six inches at the lower end, to be driven into the rock,
and the steel wedge, after the end of the bolt had been reduced
in size, (a very slim wedge, about six inches long), was requir-
ed to be entered into each bolt two or three inches before driv-
ing it through the timber and into the hole drilled in the rock,
and these holes were required to 'be about a half inch, count-
ing the thickness of the timber, in depth, less the 30 inches, so
that when the wedge reached the bottom of the hole it would
be impossible for that bolt to be drawn out. The head of the
bolt was to be up-set and driven down by a heavy hammer, so
that it would be a little below the top face of the timber. They
were putting that timber down when I went down to see how
the work was getting on, and I met a man, as I got down the
bank, who said to me, in a low tone, "You may look out for
some crooked work." He was careful not to be heard by any
