Tom went back to his work and the boys, bidding him good-by, followed Mr. Hartshorn up to the big house. He took them into a room that he said was his den. There was a big desk in it, all littered up with papers, and well filled bookcases around the room.
"Are all these books about dogs?" inquired Harry.
"Well, a good many of them are," said Mr. Hartshorn. "I have about every book on dogs that has been printed, I expect."
On the walls above the bookcases were photographs and colored pictures of dogs and horses in frames, and at one side of the room was a long leather sofa. Mr. Hartshorn seated himself at his desk and began rummaging in a drawer full of photographs, while he told the boys to be seated on the sofa.
"Now, then," he said when they were all settled, "you were asking me about the different kinds of terriers, and I guess I've got pictures of good specimens of about every kind. How many kinds of standard breeds of terriers do you suppose there are?"
"About eight, I guess," said Harry, who was a little more forward than the Whipple boys.
"Wrong," said Mr. Hartshorn. "There are nearly a hundred recognized breeds of dogs in this country, all different, and eighteen of these are terriers. To make them easier to remember, I will divide them into three classes, smooth-coated, wire-haired, and long-haired. The smooths are the bull terrier, the Boston, the smooth fox terrier, the Manchester, and the Doberman pinscher. The wires are the wire-haired fox terrier, the Airedale, the Bedlington, the Irish, the Welsh, the Scottish, the West Highland white, the Dandie Dinmont, the cairn, and the Sealyham. The long-haired ones are the Skye, the Clydesdale, and the Yorkshire."
"My!" exclaimed Ernest. "I never heard of some of them before."
"Lots of people haven't," said Mr. Hartshorn, "but they're all worth knowing. You can see nearly all of them at a big show like the one held every year in New York. I'm going to tell you something about them all, if you'd like to listen."
"Oh, yes, please do," said Ernest.
