The man nodded, and said gruffly that he would see to it, and then, as he turned away, I saw him wink at one of the men grinding at a stone and thrust his tongue into his cheek.

Just then he caught my eye, his countenance changed, and he looked as foolish as a boy found out in some peccadillo, but the next instant he scowled at me, and his fierce dark eyes said as plainly as if they spoke:

“Say a word about that and I’ll half kill you.”

I read the threat aright, as will be seen; and, turning to follow my uncles, I saw that the man was coming on close behind me, with a look in his countenance wonderfully like that with which he was being followed by Piter, who, unobserved, was close at his heels, sniffing quietly at his legs and looking as if he would like to fix his teeth in one or the other.

Seeing this I stopped back, half expecting that Piter, if left behind, might be kicked by the man’s heavy clogs. The others did not notice my absence, but went on out of the grinding-shop, and the engineer came close up to me, stooping down as I waited, and putting his face close to mine.

“Look here, mester,” he began in a low threatening tone, “do you know what’s meant by keeping thy tongue atween thy teeth?”

“Yes,” I cried; and in the same breath, “Mind the dog! Down, Piter! Down!”

The man made a convulsive leap as he caught sight of the dog, and his intention was to alight upon the frame-work of one of the large grindstones close by his side—one that had just been set in motion, but though he jumped high enough he did not allow for the lowness of the ceiling, against which he struck his head, came down in a sitting position on the grindstone, and was instantly hurled off to the floor.

This was Piter’s opportunity, and with a low growl and a bound he was upon the man’s chest. Another moment and he would have had him by the throat, but I caught him by the collar and dragged him off, amidst the murmur of some, and the laughter of others of the men.

I did not want to look as if I was afraid, but this seemed to be a good excuse for leaving the grinding-shop, and, holding on by Piter’s collar, I led him out.
