Mr. Prideaux's study was close to the front door, and his attention was suddenly directed to a violent shaking and scratching. In an instant he ran into the hall and unlocked the entrance door. A mass of filth and mud entered. This was Turk!

The dog was shivering with wet and cold. His usually clean coat was thick with mire, as though he had been dragged through deep mud. He wagged his tail when he heard his master's voice, but appeared dejected and ill. The dog was taken downstairs, and immediately placed in a large tub of hot water, in which he was accustomed to be bathed. It was now discovered that in addition to mud and dirt, which almost concealed his coat, he was besmeared with blood! Mr. Prideaux sponged his favorite with warm water, and, to his surprise, he saw wounds of a serious nature; the dog's throat was badly torn, his back and breast were deeply bitten, and there could be no doubt that he had been worried by a pack of dogs.

He was now washed clean, and was being rubbed dry with a thick towel while he stood upon a blanket before the fire. "Why, Turk, old boy, what has been the matter? Tell us all about it, poor old man!" exclaimed his master.

The dog was now thoroughly warmed and he panted with the heat of the kitchen fire; he opened his mouth, and the guinea which he had received in trust dropped on the kitchen floor!

"There is some mystery in this," said Mr. Prideaux, "which I will try to discover tomorrow. He has been set upon by strange dogs, and rather than lose the guinea, he has allowed himself to be half killed without once opening his mouth in self-defense! Poor Turk!" continued his master, "you must have lost your way old man, in the darkness and storm; most likely confused after the unequal fight. What an example you have given us in being faithful to a trust!"

Turk was wonderfully better after his warm bath. He lapped up a large bowl of good thick soup mixed with bread, and in half an hour was comfortably asleep upon his thick rug by his master's bedroom door.

THE MYSTERY EXPLAINED

Upon the following morning the storm had cleared away, and a bright sky had succeeded to the gloom of the preceding night. Immediately after breakfast Mr. Prideaux, accompanied by his dog (which was, although rather stiff, not much the worse for the rough treatment he had received), started for a walk toward the house to which he had directed Turk upon the previous evening. He was anxious to discover whether his friend had been absent, as he believed that the dog might have been waiting for admittance, and had been perhaps attacked by some dogs in the neighborhood.

The master and Turk had walked for nearly a mile, and had just turned the corner of a street, when, as they passed a butcher's shop, a large brindled mastiff rushed from the shop-door and flew at Turk.

"Call your dog off!" shouted Mr. Prideaux to the butcher, who watched the attack with impudent satisfaction. "Call him off, or my dog will kill him!" continued Mr. Prideaux.
