Ants. [In several Philadelphia houses there are numerous black or dark red ants about one twelfth of an inch long, which carry off sweet things.] Mr. Franklin was much inclined to believe that these little insects could by some means communicate their thoughts or desires to each other, and he confirmed his opinion by some examples. When an ant finds some sugar, it runs immediately under the floor to its hole, where having stayed a little while a whole army comes out, unites and marches to the place where the sugar is, and carries it off by pieces. If an ant meets with a dead fly, which it cannot carry alone, it immediately hastens home, and soon after some more come out, creep to the fly and carry it away. Some time ago Mr. Franklin put a little earthen pot with treacle in it into a closet. A number of ants got into the pot and devoured the treacle very quietly. But as he observed it he shook them out, and tied the pot with a thin string to a nail which he had fastened in the ceiling, so that the pot hung down by the string. A single ant by chance remained in the pot: this ant ate till it was satisfied; but when it wanted to get away it was under great concern to find its way out. It ran about the bottom of the pot, but in vain. At last if found after many attempts the way to get to the ceiling by the string. After it had come there, it ran first to the wall and then to the floor. It had hardly been away for half an hour, when a great swarm of ants came out, climbed up to the ceiling, crept along the string to the pot, and began to eat again. This they continued till the treacle was all eaten. In the meantime one swarm kept running down the string and the other up all day long.
