restoration of the lintels and the filling of the cavities above them.
The fourth item was the tying in of the south wall, or of the several
parts of it, with braces. This was the only feature of the plan which
would appreciably disfigure the ruin, but some such device was deemed
essential for the preservation of the south wall.

These four items consumed practically all of the amount appropriated,
and the other items of the original plan were therefore omitted. The bid
of T. L. Stouffer and F. E. White, of Florence, Arizona, covering the
four items, was accepted, and a contract was made with them, under date
of May 9, 1891, for the execution of the work for the sum of $1,985.
This contract, together with the specifications, plans, and other
drawings which formed part of it, accompany this report. It was
transmitted to the Director of the Geological Survey, and by him
approved and forwarded to the Secretary of the Interior June 6, 1891. It
was approved by the Acting Secretary June 20, 1891. Finally, on July 20,
1891, it was placed on file, together "with the bids, proposals, and all
the original papers."

A time limit of two months was made in the contract, expiring August 20,
1891, but it was changed to four months from July 1, 1891, expiring
October 31, 1891. Before the time expired, however, Mr H. G. Rizer, then
chief clerk of the Bureau of Ethnology, was ordered to proceed to Casa
Grande ruin to examine the work done and, if in accord with the terms of
the contract and the specifications, to certify the amount due the
contractors. He submitted a report, under date of November 24, 1891,
which is appended hereto. He also obtained six photographic negatives of
the work as it stood a short time before its completion, and two of
these (reproduced in plates CXX and CXXI) have been utilized in the
preparation of this report.
