Forest Survey Adopts Standard Method of Surveying Timber Block Lines By G. H. Prince, Provincial Forester, Fredericton, Mr. G. H. Prince The Forest Survey of the Crown Lands of New Brunswick, which includes the work of sur- veying and retracing the timber block lines, the cruising of the timber, the determination of the rate of growth and the classifica- tion of the soil, is being contin- ued as rapidly as possible, and already thirty per cent, of the crown lands have been examined and mapped. At the present time about thirty men are engag- ed on the field work on snow- shoes, and this number will be increased when the summer field parties are made up early in May. The following is a brief description of the first part of work, namely, "the block lines": Since the survey started, many developments in method have taken place, and chief among these changes may be said to be the permanent establishment of the boundary line be- tween timber blocks. This work is being done in advance of the timber estimating. The lines being run and quarter mile posts es- tablished and carefully marked, to be later used by the cruisers in cruising and plotting the maps and in segregating the timber estimates on each block of land. The work of surveying these lines is now carried out by forest engineers, who have also qualified as deputy land surveyors. How Block Lines Are Run The block lines are run east and west two and one-half miles apart, while every five, or in some cases seven and one-half miles, north and south lines are established known as tie lines. This method gives what is termed by engineers as "closed survey," but it does not completely divide the area in blocks two and one-half miles square (which is usual size of timber licenses) as it would if every no
