108 ANNUAL REPORT 
to go down 80 feet and more. Down to 25 feet two men can operate it ; 
from that to 50 feet a rough frame 15 to 20 feet is needed for the third 
man to stand on. Above 50 feet it is necesary to take off one or two of 
the top joints each time-the auger or drill is lifted. 
It is interesting to note Mr. Catlett's observations on drilling some 
holes, which might form a basis for the calculation of the approximate cost 
of drilling.

Serrated Pipe.—In place of the auger a pipe, provided at the end 
with sharp teeth, may be used, which is forced down into the soft material 
by twisting a two-foot handle. The sample will be a plug filling the 
pipe, representing the section of the length of the pipe. Another con- 
trivance is a pipe with sharpened edges at the end, which is driven into the 
ground. In both samplers the plug of the material is, of course, forced 
out, another section of pipe connected with the first pipe and again started 
down. Both of them can be used more effectively in connection with 
a churn drill, which is able to cut through any hard material that may 
be met. 
Whenever the material is very soft, as is the case with marl 
and marl clays, quite a number of devices are being used for doing 
this work and the most of them can be made by any mechanic without 
inuch trouble.
