G. B. Mc Keown (Draperstown).–Professor Cole, F.G.S, of Royal College of Science, reports:–“The rocks are almost certainly from one of the ‘felstone’ dykes of Devonian age that are common in the North of Ireland, with a fairly uniform northerly trend. The compact pinkish ground contains abundant well-shaped crystals of hornblende. It might possibly be from a junction of one of the older granitoid rocks with a hornblende schist. The exact locality would be required if I am to say anything more about it.” We will send the minerals for examination and will report in due course. If you care to give locality it would assist greatly and, I think, would hardly affect your interests.

G. B. Mc Keown (Draperstown) – Many thanks for details; please send specimens No. 2. We will do our best to help, only it may take some little time before the result of the analysis is known. Your notes are most interesting, send as often as possible, pencil will do. Yes! the Clubmoss is Lycopodium clavatum, Linn, or the “Stag’s-horn Clubmoss”; it is not common, but appears to be generally distributed. The curious Sycamore leaves are evidently the result of some injury to the tree; we will look into this matter further.
