A night’s sleep seems to have restored the party, for they landed at Antwerp the following morning apparently all in good spirits, and after a stroll round the town took train for Cologne, passing Liège, “which lies beautifully in a lovely wooded valley,” _en route_. After a short visit to Cologne--“here I was pleased to find Heine’s good Christopher in the Dom”--the party went on by boat to Königswinter. “Sail up the Rhine not very interesting, but the evening is exquisite and the flat country looks well.” At Königswinter they spent some days--very hot ones--climbing the Siebengebirge and geologising, with lighter intervals. One of the interludes may be mentioned:--“Peach swam across the Rhine in twelve minutes (before breakfast).” After a day or two at Königswinter the party went down the Rhine to Bonn, to see Prof. Zirkel there and to visit the museum. Bonn is somewhat briefly dismissed:--“This is a lost day. I hate Bonn ... hooked it back to Königswinter--and loafed about.” At Bonn the party met Sir Roderick Murchison, then Director-General of the Geological Survey, profanely called “the Duke” in the diary, for his mannerisms made a strong appeal to the sense of humour of the more lively members of the party. The veteran geologist--or at least so the juniors asserted--graduated his greetings in careful accordance with the official position of each. But the old chief’s genuine interest in geology was shown by his eager questions about the recent results of the Survey work in the Southern Uplands. Finally Königswinter was left, “with regret,” for the Laacher See, a detailed visit to the Eifel country being one of the great objects of the tour. James Geikie’s early work in the Ochils had aroused his interest in volcanic phenomena, and his geological notes in regard to the next section of the tour are singularly full.
