With this assurance the boy kissed his mother and hurried out of the door, and Mrs. Evans, after clearing away the remnants of their frugal breakfast, also went out to begin her daily toil at the house of a neighbor. David made his way around the cabin, and was met by Don's pointer, which, coming as close to him as the length of his chain would permit, waited for the friendly word and caress that the boy never failed to bestow when he passed the kennel in which the animal was confined. The greeting he extended to his four-footed friend was a short one this morning, for David had other matters on his mind. He confidently expected that a few days more would bring him the wished-for order from the man who had advertised for the quails, and when it came he wanted to be ready to go to work without the loss of an hour; so he was spending all his spare time in building traps. He had four completed already, and just as he had got boards enough split out for the fifth, he heard the clatter of horses' hoofs on the road and looked up to see Bert Gordon and his brother ride up to the fence. "Why, Don, I am glad to see you out again," exclaimed David, dropping his hammer and hurrying forward to greet his friend. "Thank you," replied Don, accepting David's proffered hand. "I assure you I am glad to be out again, too. It's a fearful bore to be tied up in the house for a whole week, but I was bound to come down here this morning, if I had to come in the carriage, for I have news for you," added Don, putting his hand into the breast-pocket of his coat. "Has it come?" asked David, in a voice that trembled with excitement. "It certainly has. It was addressed to me, you know, and so Bert opened it. The man says, he wants fifty dozen live quails immediately, and--but there it is, read it for yourself." Don produced the letter, and David took it with a very unsteady hand. A hundred and fifty dollars was a fortune in his eyes, a larger one too than he had hoped to earn for some years to come. He opened the letter and one glance at it showed him that the money was his, if he could only capture the required number of birds. They were to be trapped at once, the sooner the better, put into boxes, which were to be marked C. O. D. and forwarded, charges paid, to the address at the bottom of the letter. "Cod," repeated David, whose opportunities for learning how business was transacted had been very limited, "does he mean codfish?" Don and Bert laughed heartily. "No," said the former, as soon as he could speak. "C. O. D. means 'collect on delivery.'" "O," said David, in a tone of voice which showed that he did not yet fully understand. "It is nothing to be ashamed of," said Bert; "we didn't know what the letters meant until father told us."
