Not long after this, the president of the express company heard from Professor Gordon. It was a long and scholarly letter. It pointed out that the guinea pig was the cavia aparoea, while the common pig was the genus sus of the family suidae. The president then told the head of the Tariff Department that guinea pigs are not pigs and must be charged only twenty-five cents as domestic pets. The Tariff Department informed agent Flannery that he should take the one hundred sixty guinea pigs to Mr. Morehouse and collect twenty-five cents for each of them. Agent Flannery wired back. "I've got eight hundred now. Shall I collect for eight hundred or what? How about the sixty-four dollars I paid for cabbages to feed them?" Many letters went back and forth. Flannery was crowded into a few feet at the extreme front of the office. The guinea pigs had all the rest of the room. Time kept moving on as the letters continued to go back and forth. Flannery now had four thousand sixty-four guinea pigs. He was beginning to lose control of himself. Then, he got a telegram from the company that said: "Error in guinea pig bill. Collect for two guinea pigs — fifty cents." Flannery ran all the way to Mr. Morehouse's home. But Mr. Morehouse had moved. Flannery searched for him in town but without success. He returned to the express office and found that two hundred six guinea pigs had entered the world since he left the office. At last, he got an urgent telegram from the main office: "Send the pigs to the main office of the company at Franklin." Flannery did so. Soon, came another telegram. "Stop sending pigs. Warehouse full." But he kept sending them. Agent Flannery finally got free of the guinea pigs. "Rules may be rules," he said, "but so long as Flannery runs this express office, pigs is pets and cows is pets and horses is pets and lions and tigers and Rocky Mountain goats is pets. And the rate on them is twenty-five cents." Then he looked around and said cheerfully, "Well, anyhow, it is not as bad as it might have been. What if them guinea pigs had been elephants?"
