The Speech of Monkeys

On the other hand, if a homeward-bound ant was lost it would approach from the outward side of the landmark and pass in. About five feet from the ground were two small, round knots, about one-eighth of an inch in height, and a space between them of about the same width. This appeared to be one of their most conspicuous and reliable landmarks, and every ant that I saw pass in or out during the lapse of weeks passed between these two points. The burdened ant always appeared to have the right of way, and when meeting another without a burden there was no question of this right. In such a case the burden was usually held aloft, and the right of way conceded without debate. A little later in the season I had the opportunity of seeing the same colony emigrate to a point about eighty feet distant from their original abode, at which time they carried large burdens and were many days in completing their work, but the same system and methods prevailed. As far as desire can be found in life the means of expression go hand in hand with it, but I do not contend that desire alone is the origin of this faculty. So far as human ears can ascertain, the lowest forms of life appeared to dwell in perpetual silence, but there may be voices yet unheard, more eloquent than we have ever dreamed of.
