| book description |

I constructed four miniature houses of worship-a Mohammedan mosque, a Hindu temple, a Jewish synagogue, a Christian cathedral-and placed them in a row. I then marked 15 ants with red paint and turned them loose. They made several trips to and fro, glancing in at the places of worship, but not entering. I then turned loose 15 more painted blue; they acted just as the red ones had done. I now gilded 15 and turned them loose. No change in the result; the 45 traveled back and forth in a hurry persistently and continuously visiting each fane, but never entering. This satisfied me that these ants were without religious prejudices-just what I wished; for under no other conditions would my next and greater experiment be valuable. I now placed a small square of white paper within the door of each fane; and upon the mosque paper I put a pinch of putty, upon the temple paper a dab of tar, upon the synagogue paper a trifle of turpentine, and upon the cathedral paper a small cube of sugar. First I liberated the red ants. They examined and rejected the putty, the tar and the turpentine, and then took to the sugar with zeal and apparent sincere conviction. I next liberated the blue ants, and they did exactly as the red ones had done. The gilded ants followed. The preceding results were precisely repeated.
