The landing of four foot Pulpwood on streams in preparation for driving would look like a simple matter. However, if it is not properly landed the whole drive may be hung. In fact it may be practically impossible to break the landings before the water has entirely run away if this part of the work is not done in a workman-like manner. Even if it is done so that the wood can be driven the cost of piling or the cost of breaking the landings may be excessive, due to the method of piling.
