”On the Transportal of Erratic Boulders, etc,” Geol Soc Journ iv, 1848, pages 315-323 (An extract from a letter to Lyell, 1847, is of interest in connection with this essay:--”Would you be so good (if you know it) as to put Maclaren's address on the enclosed letter and post it It is chiefly to enquire in what paper he has described the Boulders on Arthur's Seat Mr D Milne in the last Edinburgh 'New Phil Journal'
[1847], has a long paper on it He says: 'Solacialists have ventured to explain the transportation of boulders even in the situation of those now referred to, by i that they were transported on ice floes,'
etc He treats this view, and the scratching of rocks by icebergs, as almost absurdhe has finally stirred me up so, that (without you would answer him) I think I will send a paper in opposition to the same Journal I can thus introduce some old remarks of mine, and some new, and will insist on your capital observations in N America It is a bore to stop one's work, but he has y,” in the Ades 156-195 This ritten in the spring of 1848

Professor Geikie has been so good as to give me (in a letter dated November 1885) his impressions of my father's article in the 'Ad points as characteristic of the work:--
”1 Great breadth of view No one who had not practically studied and profoundly reflected on the questions discussed could have written it
”2 The insight so remarkable in all that Mr Darwin ever did The way in which he points out lines of enquiry that would elucidate geological problems is eminently typical of him Some of these lines have never yet been adequately followed; so with regard to the and sympathetic treatment The author at once puts his readers into harh of inforhtful the field is to which he invites theht accomplish in it There is a broad sketch of the subject which everybody can follow, and there is enough of detail to instruct and guide a beginner and start hireat strides since 1849, and the article, if written noould need to take notice of other branches of inquiry, and to modify statements which are not now quite accurate; but ives is as needful and valuable nohen it was given It is curious to see hat unerring instinct he seems to have fastened on the principles that would stand the test of time”
