From L. C. Wedgwood   20 January [1872]

6 Q. A. St.

Jan 20th

Out of 25 worm-holes probed with a blunt wire between Jan 6 & 14 on different slopes for a few inches, 8 came to the surface nearly vertical to the slope; the rest at various angles.1

I will try some more, and when I have dug some more trenches will send the result about furrows
