diary, with the improvements he thought advisable, and some very scientific suggestions by which the river could be made to checkmate itself, like an automaton chess-player. He hung over the guards continually, observing all that was to be observed, and recorded the same under separate headings, such as "currents," "velocity," "flood-rises," with statistics without end showing that the carrying-trade of the great water highway would amount in 1950 to something so colossal that there is no room for it here, while a future for the cities that stud its banks was predicted that would satisfy their most ambitious citizens. His heart was not in Louisville nor in the Mammoth Cave, though he went over the first religiously and examined the latter carefully, collected specimens, and even thrilled faintly over an eyeless fish, which aroused considerable enthusiasm in Mr. Heathcote. He was not really himself until he was again on the river, doing a little dredging and sounding on his own account. At Cairo he expanded almost as much as his subject, and for a long while afterward was never weary of tracing the blue and yellow currents that fuse so reluctantly and imperfectly that out in the Gulf of Mexico, it is said, one comes upon patches of the Missouri of the most jaundiced, angry hue. The sombre majesty of the stream was quite lost upon Mrs. Sykes, who saw in it only "an ugly, wicked-looking river, with a lot of dirty-white villages along its mud banks." Her attention was given to the passengers and the clerk,--especially the latter. "A clerk that talks to the ladies in the cabin about literature and the dramar! Only fency!" she said to Miss Noel. "And such comical blackies, that the ladies call 'aunty,' and that call me 'honey' and 'child.' As like as not you'll see a snag coming up through the bottom of the boat presently, and you had better try one of the life-preservers on and see how it works; though, after all, we may be blown up instead. Of course we are racing. I am sure of it." "Dear, dear! How _very_ dreadful! How did you discover that? It should really be made known. I shall speak to the captain. I really can't consent to being _raced_ with," replied Miss Noel, who did not make sufficient allowance for Mrs. Sykes's love of the sensational. "Robert must call a meeting and protest, or something."
