In this article we show a few of these curious log-marks--odd artistic inventions of the untrained minds of the lumber-camps. There is no attempt at uniformity in ideas. Anything that has the least bit of distinctiveness about it is sufficient for the purpose, which explains the presence of pound-marks, tea-pots, frogs, babies, yokes, division signs, and wheel-barrows in the illustrations for this article. [Illustration] The instrument with which the "scaler" places the mark upon a log is in the shape of a sledge-hammer, the back of the hammer portion having upon it a device similar to the log-mark of the man by whom he is employed and to whom the logs belong. The log-mark itself is raised to a height of about 1½in. or 2in. above the surrounding surface of steel, and when the sawed end of a log is struck with it, the mark of the owner is punched into the end of the log to a depth which prevents its obliteration, unless the whole end of the log is sawed off and removed. Crude designs, differing from the regular log-mark, are sometimes cut into the bark of the log to assist in more readily identifying the owner. Copies of log-marks and cattle-brands are, as provided by law, placed on a file in the office of the county recorder of deeds in the county in which the cattle owner or lumberman operates. For greater convenience the ice in the river is thickly covered with the logs as spring approaches. When the break-up of ice in the river occurs, and the stream is swollen by the melting of snow and the early spring rains, what is called the log "drive" commences. In some portions of the lumbering regions the disappearance of the forests has left the saw-mills further and further from the product without which they cannot operate, and the logs have to be floated great distances. Thus, a "drive" of 100 or 200 miles is nothing unusual, and on the Mississippi river logs are frequently taken as much as 300 miles. On one river perhaps a dozen or more lumbering firms, having no connection with each other, are operating, and when spring comes all their logs are rolled into the stream, to soon become so mixed up that the novice naturally becomes of the opinion that their separation is an impossibility. The work during a log "drive" is the hardest and most dangerous connected with the lumbering industry.
