I enclose herewith the calibration of 
the gauges. The maximum error is six thousand the of an Inch, well 
within the limit allowable. 
The wor’; f calibration was done by Mr. A. L. Thomas of my 
department and was done with considerable ca; . I think the re- 
sults are accurate within a limit of less than a quarter of a 
thousandth or one four thousandth of an Inch. 
Trusting t> -»t this will serve your purposi , I am 
Yours very truly.

We consider this as near a perfect caliper as we can imagine. As 
soon as you have some ready we would like to get four or five dozen.

Please send me one dozen of your tree gauges, they will be invalua- 
ble in the hands of my graders. Think I will have the name of each 
grader engraved on his gauge, which will make him feel that it is his 
property and he will take greater interest in using it.
