Thanks for letter [8137]. Finds observation at Stonehenge of depth of mould at different parts of slope “most valuable”.


Jan 3d.

Shall you be coming to Down within a month or so? We cannot reconcilethe large & capital diagram with the 2d page of your letter: I imaginethey refer to different parts.f3 Again I am curious to know whether in the middlepart of slope in diagram, whether the inclination is greater, for the furrowsfor a space are decidedly deeper than above or below.— I havemade pencil notes on your letter,f4 so that I shall not forget what to
