GROUND WATER BRANCH MEMORANDUM NO. 59.32

To:       District Chiefs and Staff Officials, Ground Water Branch

From:     Acting Chief, Ground Water Branch, Washington, D. C.

Subject:  EQUIPMENT AND SUPPLIES - Microbarograph Charts
                                   (No. 5-1071-F)

Reference is made to Ground Water Branch Memorandum No. 58.45,
dated April 11, 1958, inquiring as to your interest in and need
for the subject charts calibrated in feet of water instead of
inches of Mercury.  A sample chart is attached.

As a result of your reply the Washington office has underwritten
the initial production costs and the charts are now available from
The Instruments Corporation, Baltimore, Maryland.  Orders should
be placed by the usual method.  No price information has been
received but it is assumed that the cost will be the same as for
the charts presently used.
