“I’m afraid the doctor can’t afford it, Will.”

“Afford it!” he exclaimed; “why, mother, I wouldn’t think of taking the wages unless I felt sure of making a profit. He seems mighty certain about it, and if work will help to win out, we’ll do it, sure as shootin’!”

Which proved that he had caught some of the doctor’s own enthusiasm.

For a week the boy heard nothing more about the partnership, but at the end of that time a load of lumber arrived from the Bingham lumber yard, and soon after Joe Higgins, the carpenter, walked up to the barn with his basket of tools, and with a nod to Will took off his coat and started to work.

Next day came the doctor with a big, legal looking document for Will to sign, which he first read in a solemn voice from beginning to end. It set forth clearly the terms of their contract, and after the boy had signed his name under the doctor’s he began to feel the magnitude of the undertaking, and the responsibility put upon his young shoulders. Doctor Meigs also brought more literature treating of mushroom culture, which he advised Will to study carefully.

Joe Higgins worked three weeks repairing the barn. He not only made it what he called “air-tight,” but in the east end he partitioned off a room, and built a floor to it, and then put an outside window and door in, making it very cozy and comfortable. This was to be the “office,” where the heater was also to be placed, so that it would warm the room as well as supply hot water to the pipes extending under the ground in all directions throughout the interior of the big barn.

The room was hardly completed before the heater arrived from the city, with men to set it up and arrange the system of pipes. Will dug all the trenches for the pipes to lie in, and then with Egbert’s help covered them over again. Also the two boys devoted days to another important work, which was the placing of straw all around the outside edge of the barn, and covering it with a bank of earth that reached well up onto the boarding. This was to keep the frost from getting inside.

The wisdom of the doctor in starting this work in August was now apparent, for the entire month was consumed in getting the barn in shape and spading up the rich soil ready to receive the mushroom spawn.

Early in September the industry was started, and in a few days thereafter small mushrooms, that looked like buttons, thrust their heads above the earth within the warm, damp barn, and speedily grew to a size that permitted them to be marketed.

The doctor carried the first picking home with him, and Will took the next lot to the big house and sold them to the astonished and delighted Nora, who placed an order for a pound of them every week. But soon the crop began to mature very fast, and by the doctor’s orders Will packed them in paper boxes holding a pound each, and afterward arranged the boxes in a neat crate, which he shipped by express to the wholesale grocer in the city whose children their grandfather was so greatly interested in. The doctor supplied the boxes and crates, and on the former was printed: “Carden & Co.’s Fresh Mushrooms. Warranted Wholesome and Delicious.” And below followed several recipes for cooking mushrooms, printed for the benefit of those who were unaccustomed to preparing them. Nora furnished some of the recipes, and old Mrs. Meigs the rest, so Will felt sure they would be successful.
