“Jenkin was fortunate in having an excellent education. His mother took him to the south of Scotland, where, chiefly at Barjarg, she taught him drawing among other things, and allowed him to ride his pony on the moors. He went to school at Jedburgh, and afterwards to the Edinburgh Academy, where he carried off many prizes. Among his schoolfellows were Clerk Maxwell and Peter Guthrie Tait, the friends of his mature life.”
