The more I looked at them, the more I was impressed by their absurd resemblance to each other.

They were dressed in the same coarse homespun, carried similar sticks, were equally begrimed about the nose with snuff, and each wound in an identical plaid of what is called the shepherd's tartan.

In a back view they might be described as indistinguishable; and even from the front they were much alike.

An incredible coincidence of humours augmented the impression.
Thrice and four times I attempted to pave the way for some exchange of thought, sentiment, or--at the least of it--human words.

An _Ay_ or an _Nhm_ was the sole return, and the topic died on the hill-side without echo.
