Xperi^mt. 1. Measurement of depth of furrows at top and bottom of slope— Old ploughed land has been pasture at least 24 years. Field sloping in 2 directions, but much most along furrows. Measured by laying a straight rod across from ridge to ridge, and measuring distance from furrow to rod.²

It was impossible in above experiment to obtain very accurate results,— any little irregularities in the surface making all the difference. There were marks of draining-pipes running across furrows n^r. top & bottom

Experi^mt. 2— Trenches dug one on ridge, one in trough of furrow side by side in same field on slope. Jan. 11^th. Line of worm-mould very ill-defined— No apparent difference

Beginning of Feb. Two more trenches dug in same field on nearly flat ground along line of furrow.

Worm-line very ill-defined only to be seen by an occasional bit of charcoal. These are very rare, but form a sufficiently straight line I think to preclude chance

Experi^mt. 3. A sod dug out near top of steep slope in garden and at bottom. (Feb 6^th.)

Ex^pt. 4 Worm mould on common near sq^re. yard 3–4 in.

On terrace near sq y^d. 3$\frac{3}{4}$³
