“Well, you see, there are the bicycles. I don’t think we can make it more than sixpence. And I tell you what: we shall have to keep accounts. I’ll buy an account-book. You’re very good at arithmetic—you’ll like keeping accounts,” said the Terror suavely.

Since her mouth was full of luscious jam tart, Erebus did not feel that it would be delicate at that moment to protest. Therefore on leaving the shop the Terror bought an account-book. His distrust of literature prevented him from paying more than a penny for it. From the stationer’s he went to an ironmonger’s and bought a saw, a brace, a gimlet, a screw-driver and two gross of screws—his tool-box had long needed refilling. Then they mounted their machines proudly (they had learned to ride on the machines of acquaintances) and rode home. After their visit to the confectioner’s they rode rather sluggishly.

They were not hungry, far from it, at the moment; but half-way home the Terror turned out of the main road into the lanes, and they paused at a quiet orchard, in a lovely unguarded spot, and filled the cat-basket on Erebus’ bicycle with excellent apples. The tools had been packed into the Terror’s basket. They did not disturb the farmer’s wife at the busy dinner-hour; the Terror threw the apples over the orchard hedge to Erebus.

As he remembered his bicycle he said dreamily: “I shouldn’t wonder if these bicycles didn’t pay for themselves in time.”

“I said there were orchards out here where they didn’t know us,” said Erebus, biting into a Ribston pippin.

They reached home in time for lunch and locked away their bicycles in the cow-house. At lunch they were reticent about their triumphs of the morning.

After lunch they went to the cow-house and took measurements. It had long been unoccupied by cows and needed little cleaning. It was quite suitable to their purpose, a brick building with a slate roof and of a size to hold two cows. The measurements made, they went, with an important moneyed air, down to the village carpenter, the only timber merchant in the neighborhood, and bought planks from him. There was some discussion before his idea about the price of planks and that of the Terror were in exact accord; and as he took the money he said, with some ruefulness, that he was a believer in small profits and quick returns. Since immediate delivery was part of the bargain, he forthwith put the planks on a hand-cart and wheeled them up to Colet House. The Twins, eager to be at work, helped him.

For the rest of the day the Terror applied his indisputable constructive genius to the creation of cat-hutches. That evening Erebus wrote his warm letter of thanks to Lady Ryehampton.

The next morning, with a womanly disregard of obligation, Erebus proposed that they should forthwith mount their bicycles and sally forth on a splendid foray. The Terror would not hear of it.

“No,” he said firmly. “We’re going to get the cats’ home finished before we use those bicycles at all. Then nobody can complain.”
