“ If more than five days is required for a given excursion, I am in the habit of taking a pack animal to carry my outfit, as I can not conveniently carry in a pack provisions for more than that number of days. In calculating the details of an outfit one must first determine the weight he is able or willing to carry. If the weight carried is too great the mobility is too much reduced. Yet enough in the way of food, clothing and bedding must be carried to prevent too much risk to the health from short rations and exposure. ”
