He had a pair of particularly stubborn mules to haul his boat, and it occurred to him that he might devise some scientific method of inducing the said mules to move whenever they were inclined to be baulky.  Both mules had phlegmatic temperaments; and when they made up their minds to stop, they would do so and refuse to go, no matter with what vigor the boy applied the whip.  Captain Binns therefore bought a tow-line made of three strands of galvanized wire; and placing iron collars upon the necks of the mules, he fastened the wire to them, and then he got a very strong galvanic battery and put it in the cabin of the boat, attaching it to the other end of the line, forming a circuit.

[Illustration:  A PERPLEXED MULE]

The first time the mules stopped to reflect, the captain sent a strong current through the wire.  The leading mule gave a little start of astonishment, and then it looked around at the boy upon the tow-path with a mournful smile that seemed to say, “Sonny, I would like to know how you worked that?” But the mules stood still.  Then the captain turned a stronger current on, and the mule shied a little and looked hard at the boy, who was sitting by whittling a stick.  The captain sent another shock through the line, and then the mule, convinced that that boy was somehow responsible for the mysterious occurrence, reached over, seized the boy’s jacket with his teeth, shook him up and passed him to the hind mule, which kicked him carefully over the bank into the river.

The mules were about to turn the matter over in their minds when Captain Binns sent the full force of the current through the wire and kept it going steadily.  Thereupon the animals became panic-stricken.  They began to rear and plunge; they turned around and dashed down the tow-path toward the boat.  Then the line became taut; it jerked the boat around suddenly with such force that the stern of it broke through a weak place in the bank, and before the captain could turn off his battery the mules had dashed around the other side of the toll-collector’s cabin, and then, making a lurch to the left, they fell over the bank themselves, the line scraping the cabin, the collector, three children and a colored man over with them.  By the time the line was cut and the sufferers rescued the mules were drowned and all the water in the canal had gone out through the break.  It cost Captain Binns three hundred dollars for damages; and when he had settled the account, he concluded to wait for the report of that committee before making any new experiments.

The report of the committee upon improved locomotion was submitted to the company during the following summer.  It was a long and exceedingly entertaining document, and the following extracts from it may possess some interest:
