As soon as the three Wheelers who were guarding the mound saw them, they began to shout their wild cries and rolled swiftly toward the little group, as if to capture them or bar their way. But when the foremost had approached near enough, Tiktok swung the tin dinner-pail and struck the Wheeler a sharp blow over its head with the queer weapon. Perhaps it did not hurt very much, but it made a great noise, and the Wheeler uttered a howl and tumbled over upon its side. The next minute it scrambled to its wheels and rolled away as fast as it could go, screeching with fear at the same time.

"I told you they were harm-less," began Tiktok; but before he could say more another Wheeler was upon them. Crack! went the dinner-pail against its head, knocking its straw hat a dozen feet away; and that was enough for this Wheeler, also. It rolled away after the first one, and the third did not wait to be pounded with the pail, but joined its fellows as quickly as its wheels would whirl.

The yellow hen gave a cackle of delight, and flying to a perch upon Tiktok's shoulder, she said:

"Bravely done, my copper friend! and wisely thought of, too. Now we are free from those ugly creatures."

But just then a large band of Wheelers rolled from the forest, and relying upon their numbers to conquer, they advanced fiercely upon Tiktok. Dorothy grabbed Billina in her arms and held her tight, and the machine embraced the form of the little girl with his left arm, the better to protect her. Then the Wheelers were upon them.
