Number 10 was located about four rods from number 8, on 

 the same side of the road and was about the same size and

 deeper by the successive use of a half-inch, a three-eighths-inch,

and a one-fourth-iuch bit. Four different sections of the hole 

 were thus formed, and into each section was driven a tube of

These tubes fitted one within another, extending outside the 

 tree to different lengths and were fitted with funnels and tubiug 

 as shown in Fig. 2.
