However, Mr. Harwood thought it best to keep them at a safe distance, and when they approached within a hundred yards of the train, suddenly commanded them to halt by raising his right hand with the palm in front, and waving it backward and forward several times. They, upon this, stopped their horses, and consulted together a few moments, then fell into a posture indicative of rest. Then, Mr. Harwood raised his hand again and moved it slowly from right to left. This they understood to mean "who are you?" One of the oldest of them immediately replied by placing a hand on each side of the forehead, with two fingers pointing to the front, to represent the narrow, sharp ears of a wolf.
