Quite a quantity of stores were bought at Albany, for the voyage up the Hudson had lasted longer than any one had supposed it would, and the provisions were getting low. No unnecessary time was spent in buying these stores, for a fair wind was blowing, and all the boys were anxious to take advantage of it. By ten o’clock they were again afloat; and soon after noon they reached Troy and entered the canal.

The canal basin was crowded with canal-boats, and to avoid accidents the Whitewing’s mast was taken down, and the oars were got out. Harry knew that, in order to pass through the locks, it would be necessary to pay toll, and to procure an order from the canal authorities directing the lockmen to permit the Whitewing to pass. The canal-boatmen, of whom he made inquiries, told him where to find the office, which was some little distance up the canal. When the office was reached, an officer came and inspected the boat, asked a great many questions about the cruise up the Hudson, and seemed to be very much interested in the expedition. He told the boys that the water was low in the Champlain Canal, and that the lockmen might not be willing to open the locks for so small a boat; but that they could avoid all dispute by entering the locks at the same time with some one of the many canal-boats that were on their way north. He charged the Whitewing the enormous sum of twenty-five cents for tolls, and gave Harry an important-looking order by which the lockmen were directed to allow the skiff Whitewing, Captain Harry Wilson, to pass through all the locks on the canal.

GOING THROUGH THE LOCK.

Thanking the pleasant officer, the boys pushed off. After they had passed the place where the Champlain Canal branches off from the Erie Canal, they were no longer troubled by a crowd of canal-boats, and were able to set the sail again. Unluckily, the mast was just a little too high to pass under the bridges, and at the first bridge which they met they narrowly escaped a capsize—Jim succeeding in getting the mast down only just in time to save it from striking the bridge. They had hardly set sail again when another bridge came in sight, and they could see just beyond it a third bridge. It would never do to stop at every bridge and unship the mast; so Harry went on shore, borrowed a saw from a cooper’s shop, and sawed six inches off from the top of the mast, after which the bridges gave them no more trouble.

The boys were very much interested in passing the first lock. They slipped into the lock behind a big canal-boat, which left just room enough between its rudder and the gate for the Whitewing. When the lockmen shut the gate behind the boat, and opened the sluices in the upper gate, the water rose slowly and steadily. The sides of the lock were so steep and black that the boys felt very much as if they were at the bottom of a well; but it was not many minutes before the water had risen so high that the upper gates were opened, and the big canal-boat and its little follower were released.

Passing through a lock in a small boat, and in company with a canal-boat, is not a perfectly safe thing to do; for if the ropes which fasten the canal-boat should break—which they sometimes do—the water rushing in through the sluices would force the canal-boat against the lower gate, and crush the small boat like an egg-shell. It is therefore best always to pass through a lock alone, or in company with other small boats. The danger, however, is in reality very slight, and very few accidents occur in canal locks.

The wind died away before sunset; and the boys having had only a light lunch, which they ate on the boat, were glad to go ashore for supper. They bought some corn from a farmer, and roasted it before the fire, while some nice slices of ham were frying, and the coffee-pot was boiling, and so prepared a supper which they greatly enjoyed. The moon came up before they had finished the meal, and they felt strongly tempted to make another attempt at night-work.

“I’ll tell you what we can do,” exclaimed Harry. “Instead of rowing, let’s tow the boat. One fellow can tow while another steers, and the rest can sleep in the boat.”

“All right,” said Joe. “I’m willing to be a mule. Only I’d like to know where my harness is coming from.”
