"Well," said Mr. Hartshorn, arranging his photographs, "first let me explain what a terrier is. Most of them come from England and Scotland. A few from Wales and Ireland. Terrier means earth dog, and that's what they were called hundreds of years ago when they were first used to hunt animals that run into the ground or under stones. They had to be brave and gamey and not too big, and they became very active little dogs and mighty efficient. At first, some were smooth-coated and some wire-coated. Finally, however, Englishmen began to breed certain favorite kinds, and so the different breeds were gradually established.

"One of the oldest kinds is the Manchester or black-and-tan terrier. He was first bred by the mill hands in the Midland counties of England where he was famous as a ratter. Here's a picture of one. Handsome chap, isn't he? Nice, intelligent dog, too. His ears are cropped but his tail isn't. The white bull terrier is a near relative of the Manchester. I've already told you about him.

"Now here's the Boston. I guess you know this kind."

"Oh, yes," said Ernest. "Theron Hammond has one named Alert."

"This is an American-made breed," said Mr. Hartshorn, "out of British raw material. Some Boston fanciers developed it from the brindle bull terrier about 1890. It's one of the most popular breeds here now. A smallish dog—sometimes too small, I think—brindle and white. And here's the smooth fox terrier. You've seen lots of those. Another small one, not over twenty pounds. He was developed from the old English working terrier about fifty years ago.

"Now here's one that I don't believe you know. It's a Doberman pinscher. Funny name. Wonderfully smart dog, though. They call him the dog with the human brain. He comes from Germany, where he was first a watchdog and was later trained as a police dog. I believe the first ones were brought over here in 1907. A muscular dog, weighing forty or fifty pounds. He is marked like the Manchester but his coat is less silky.

"Now we come to the wires. The wire-haired fox terrier is really just like the smooth, but he looks quite different because of his stiff, wiry coat. Then there's the Airedale. You know about those. Best all-round dog in the world in my opinion. This is a Bedlington. You won't see many of those. Has a head like a lamb, hasn't he? And notice the silky topknot. He's a good little sporting dog if he does look so mild. They're mostly blue-gray and tan, and weigh about twenty-four pounds.

"Here's the liveliest one of the lot, the Irish terrier. Sometimes they call him the dare-devil. He's a great little scrapper. He comes from Ireland, of course. He's a red dog, weighs twenty-four pounds, and makes one of the best comrades a boy can have. The Welsh terrier is related to the wire-haired fox, though he looks more like a small Airedale, being black and tan. He's a little smaller than the Irishman.

"Several terriers come from Scotland, and as you can see from these pictures they're a short-legged, strong-headed, long-bodied lot. That's because they were bred to go into the ground and the piles of rocks after badger and such-like game. They had to be pretty tough to manage it, too. This is the cairn terrier. He used to be called the Highland terrier, and I guess he's more nearly like the original terrier of Scotland than any of the others, He came from the Hebrides Islands. I expect you've never seen one, for they aren't common in this country. But they're jolly little beggars. They're the smallest of the lot, weighing only twelve to fifteen pounds, but mighty hardy and gamey. They are various sandy and grizzled colors and always have this foxy little head.
