"Sure," said the shipper, and the old boatman began to shovel the shells from the scows into his own boat.

"Now I wonder what he wants with those shells," thought Alec. Then, following his rule, he decided to watch and see what the old fellow did with them.

As there were six scows to clean, it was evident that it would take him some time to get all the shells; so Alec walked on. He went past pier after pier. On most of them, men were just finishing their day's work, sewing up and trundling away the last of their oysters. On some piers were great rows of barrels, such as had sheltered Alec from the wind on Captain Rumford's pier. On practically every pier baskets were stacked up like the barrels; and when Alec noticed how wet they were, he rightly guessed that they were left out in the wind to dry. On some piers seines were hung up on long poles that extended from rafter to rafter. Yawl boats, most of them equipped with gasoline engines, floated in the slips. And several had been stowed on piers. One by one the oyster craft were tying up at the ends of the piers, so that the river began to present as crowded an appearance as it had in the early morning.

At the end of the pier shed was a big blacksmith shop, with quantities of dredges, anchors, and other boat equipment to be mended.

Alec went around the end of the pier house and started back along the wide shipping platform. He was amazed to see that three lines of cars on three parallel tracks stood ready to receive the day's yield of oysters. Little, metal markers, labeled Scranton, Wilkes-Barre, Williamsport, New York, and so on, were stuck in the doors of the various cars, to help the men trucking the oysters get them in the proper cars. The strings of cars reached the full length of the oyster sheds, which must have been at least two hundred yards; and Alec saw at once that when the three strings were coupled in one train, there would be considerably more than a third of a mile of oysters going to market. When he remembered that he had seen another train at the oyster sheds across the river, he suddenly realized what an enormous industry this oyster business was, and what a lot of money there must be in it for successful oyster shippers. It made him more determined than ever to look into the situation well and see if his opportunity in life might not lie right here.

As Alec walked along the shipping platform, his wonder grew. Here were telegraph stations, butcher shops, ship-chandleries, where one could buy almost anything needed aboard ship, and so on, as well as the offices of the oystermen. Overhead swung the signs of the different shippers, and Alec was interested in reading them. On these signs he saw many of the names he had seen earlier in the day on the oyster-boats themselves; and he guessed that many of these boats, like the Bertha B and the Mary and Willie, must have been named after members of the shippers' families.

By the time Alec had completed the circuit of the oyster sheds, and gotten back to the slip where the old man was collecting shells, it was almost dark. The shell collector was just sculling his craft out of the slip into the river. Alec walked to the end of the pier and saw that the man was pointing his boat up-stream. Deciding to follow him on land, Alec hurried along under the pier shed in pursuit.

Long before this the electric lights had been lighted, and Alec did not realize how dark it really was until he had passed beyond the shed under the open sky. At first he could hardly see anything. Once he glanced back, and in the faint light from the pier shed made out the form of a man behind him. As he went on, he heard footsteps coming close, but thought nothing of it. He came to a little landing place built of a few planks, that projected well out over the water. His eyes had now grown accustomed to the dark, and he cautiously made his way out on this landing, to look for the shell collector. He was surprised to hear a tread behind him on the landing. Just as he turned to see who was coming, there was a rush of feet on the planks, a hoarse voice cursed him viciously, and in another instant powerful arms grasped him and flung him headlong into the swirling tide.
