ascensionist

Mr. Reed is an accomplished rock climber who is known in climbing circles as a first ascensionist — someone who develops new lines, or routes, up a particular destination.

The ascensionist said nothing to the contrary,--he trembled more violently,--but the people sought for him who had said it, and cried, "It is he with the mask, for he is no more to be found."

Then he would hastily take down his ascensionist outfit and, swearing at himself, put it on.

������ else could they suppose of the president of an Alpine Club, a renowned ascensionist, of whom his friends spoke only with "Ahs!" and exultant gestures.
