Sometimes, when he was floored, a friend would try to coax him to another drink by temptingly placing a well-filled glass near his nose, an invitation that would generally excite in him an 98 effort to rise and a very comical and unsteady attempt to follow the lead of the disappearing glass; usually he would wobble over, but would right himself enough to sit up and gaze intently after the fascinating beverage beyond his reach. In respect to demeanor or quantity, he was quite human; he never knew he was a beast of himself, or when he had enough. I do not pretend to say that Tim’s habits of drink were not reprehensible; for the pures of this true story he must he the blame. It was certainly not the fault of his ; he simply suffered the usual penalty of hing too many thoughtless and convivial friends.
