This is a place where a mole has dug his tunnel in the night to get things to eat. Moles dig deep down, too, under the surface where no one can see them, and when they do not uproot the grass or the garden plants, they do little harm. It is only when they come near the top that you can see the ridge they make.
Sometimes cats catch moles when they come out on top of the ground, thinking them a sort of mouse. The mole's fur is very fine and soft, and would make a fine cloak, only it would take many skins to make one large enough to wear.
"Well, I'm glad Roly-Poly is all right," said Mab, as she took the little dog from Hal, who was holding hint, and petted him on his head.
"Yes, you may put him down now," spoke her father. "And we'll go dig the potatoes. Mother wants some for dinner, and I want to show you children how to get them out of the ground. For we will soon be digging them to put away for winter."
When Hal and Mab reached the potato part of the garden, which was the largest of all the plots, the children saw that many of the green vines were getting brown and withered.
"Why, the vines are dying!" exclaimed Mab. "Did a mole spoil them, Daddy?"
"No, but the potatoes have grown as large as they ever will be, and, there being no more need of the vine, it is drying up. It has gone to seed, just as a dandelion goes to seed, in a way, though we call the potatoes 'tubers' instead of seed. There may be potato seeds, that come when the potato blossom dries up, for all I know, but I have always planted the eyes of the tubers and so does everyone else. Now to show you how to dig."
Mr. Blake had planted two kinds of potatoes, early and late, and it was the vines of the early ones that had dried up. Later on the others would dry, and then it would be time to dig their tubers to put down cellar for the long Winter.
"First you pull up the vine," said Daddy Blake, and he tore one from the earth, many of the potatoes clinging to it. These he picked off and put in the basket. Then, with a potato hook, which is something like a spading fork, only with the prongs curved downward like a rake, Daddy Blake began scraping away the dirt from the side of the hill of potatoes.
