Tom, meanwhile, made frequent visits to New York, returning late at night. One day she brought home a circular with cuts of several improved kinds of hoisting-engines with automatic dumping-buckets. She showed them to Pop under the kerosene lamp at night, explaining to him their advantages in handling small material like coal or broken stone. Once she so far relaxed her rules in regard to Jennie's lover as to send for Carl to come to the house after supper, questioning him closely about the upper rigging of a new derrick she had seen. Carl's experience as a sailor was especially valuable in matters of this kind. He could not only splice a broken “fall,” and repair the sheaves and friction-rollers in a hoisting-block, but whenever the rigging got tangled aloft he could spring up the derrick like a cat and unreeve the rope in an instant. She also wrote to Babcock, asking him to stop at her house some morning on his way to the Quarantine Landing, where he was building a retaining-wall; and when he arrived, she took him out to the shed where she kept her heavy derricks. That more experienced contractor at once became deeply interested, and made a series of sketches for her, on the back of an envelope, of an improved pintle and revolving-cap which he claimed would greatly improve the working of her derricks. These sketches she took to the village blacksmith next day, and by that night had an estimate of their cost. She was also seen one morning, when the new trolley company got rid of its old stock, at a sale of car-horses, watching the prices closely, and examining the condition of the animals sold. She asked the superintendent to drop her a postal when the next sale occurred. To her neighbors, however, and even to her own men, she said nothing. The only man in the village to whom she had spoken regarding the new work was the clerk of the board, and then only casually as to the exact time when the bids would be received. The day before the eventful night when the proposals were to be opened, Mr. Crane, in his buggy, stopped at her house on his way back from the fort, and they drove together to the ferry. When she returned she called Pop into the kitchen, shut the door, and showed him the bid duly signed and a slip of pink paper. This was a check of Crane & Co.'s to be deposited with the bid. Then she went down to the stable and had a long conference with Cully.
