The children agreed as they went home to dinner that the Porter was most delightful company.

Next day was Roberta's birthday. In the afternoon she was politely but firmly requested to get out of the way and keep there till tea-time.

“You aren't to see what we're going to do till it's done; it's a glorious surprise,” said Phyllis.

And Roberta went out into the garden all alone. She tried to be grateful, but she felt she would much rather have helped in whatever it was than have to spend her birthday afternoon by herself, no matter how glorious the surprise might be.

Now that she was alone, she had time to think, and one of the things she thought of most was what mother had said in one of those feverish nights when her hands were so hot and her eyes so bright.

The words were: “Oh, what a doctor's bill there'll be for this!”

She walked round and round the garden among the rose-bushes that hadn't any roses yet, only buds, and the lilac bushes and syringas and American currants, and the more she thought of the doctor's bill, the less she liked the thought of it.

And presently she made up her mind. She went out through the side door of the garden and climbed up the steep field to where the road runs along by the canal. She walked along until she came to the bridge that crosses the canal and leads to the village, and here she waited. It was very pleasant in the sunshine to lean one's elbows on the warm stone of the bridge and look down at the blue water of the canal. Bobbie had never seen any other canal, except the Regent's Canal, and the water of that is not at all a pretty colour. And she had never seen any river at all except the Thames, which also would be all the better if its face was washed.

Perhaps the children would have loved the canal as much as the railway, but for two things. One was that they had found the railway FIRST—on that first, wonderful morning when the house and the country and the moors and rocks and great hills were all new to them. They had not found the canal till some days later. The other reason was that everyone on the railway had been kind to them—the Station Master, the Porter, and the old gentleman who waved. And the people on the canal were anything but kind.

The people on the canal were, of course, the bargees, who steered the slow barges up and down, or walked beside the old horses that trampled up the mud of the towing-path, and strained at the long tow-ropes.
