“He certainly will; a dog is always hungry, and more than half a day has passed since he ate; nothing suits him better than raw meat.”

“We have a supply, and he shall feast to his heart’s content.”

So he did, the food being brought out and placed in front of the canine guest, who would have eaten a good deal more had his master permitted. Meekly accepting the decision, Zip lay down at young Burton’s feet, contented and happy throughout the remainder of the evening, and glad to stay outside until the youth rejoined him in the morning.

“You know what matchless policemen the Belgian dogs make in that country, in France, and in New York and other cities. Some three years ago Long Island became so pestered by thieves that Robert E. Kerkham, superintendent of the railway police, saw that something drastic had to be done. The thieves dynamited station safes, burglarized private dwellings and more than once killed and injured railway policemen while they were trying to arrest the criminals. Those men used fleet horses and automobiles, and despite everything that could be done, grew bolder and more successful.

“Superintendent Kerkham, finding that his patrolmen were powerless, decided to call in the help of dogs, with whose striking success abroad and at home he was familiar, but he made a new departure by taking bloodhounds instead of the usual police dogs, for the former would not only guard property but would track the thieves. He bought a pair from the stock imported from England more than twenty years ago. These are of the purest blood, and superior to all others. Zip is from the same stock. A peculiarity of this dog is that in no circumstances will he take up a doubtful trail, but will pick up the true scent, no matter how faint, and never abandon it so long as it actually exists. They know not the meaning of fear, and will stick to their work so long as they can move or breathe. Some of those dogs have pedigrees that reach backward to the time of William the Conqueror.

“The couple which Mr. Kerkham purchased are named Bob and Nellie. They had to be trained, but they learned fast. They will take the scent from any article that has been lately handled by the person they are after.”

“How old a trail will serve them?” asked the Scout Master.

“Of course the freshest scent is the best. Zip was all of seven hours behind me to-day. I have tested him on double that time and he seemed to have little or no difficulty. They have taken a trail twenty-four hours old, and precisely what it is that guides them in such a case is more than any one can understand. A man is known to have left a house at a certain time, and twenty hours later it is decided to pursue him with the aid of a bloodhound. A glove, or hat, or shoe that he is known to have worn is held in front of the dog; he sniffs at it, dashes out of doors, circles back and forth and around the grounds until he strikes the corresponding scent; up goes his head, his tail wags and he bays his pleasure. A hundred yards farther, and he drops his nose to the ground to make sure he has not lost his clue.

“Perhaps the scent grows faint or disappears. In that case he runs back and circles about until he picks it up again, when he is off once more. You must remember that while all this is going on there is a man tugging at the leash, for this is necessary to protect the thief. As the trail grows fresher, the fierce eagerness of the hound increases; he knows he is close upon his quarry and sharp words and powerful pulling are necessary to prevent him from bounding straight at the throat of the cowering wretch. Should he start to run it is almost impossible to restrain the dog, but when he sees the criminal is under arrest, he is satisfied, becomes quiet, and is ready to tackle the next job.”

“Will you tell us of some of the exploits of Bob and Nellie, who you say are perfect specimens of their kind?”
