Comparative Height of Original Stand of Douglar Fir Timber and lo-Storv Buildings in
Seattle.
The cite of the City of Seattle war originally covered with a denee forest of large Douglaa Fir, Red Cedar, Hemlock and Spruce timber, euch ac ic now being logged on the wertcrn rloper of the Carcade Mountaine in Waehingtorr, Orcgon and Britirh Columbia, and many rueh treee rtood on thc eitee of thi Cobb, White, Henry and Stuart Buildingr-not .in regregated groupr but with thcir interlocking topr rhading the earth in perpetrral gloom, the lack 'of runrhine killing ofr thc wcaker treer, and cauring thc dropping of the lowel limbr on the rturdy eurvivorr aa they grew to hcightr which can only be rcalized in a compariron ruch ar thir.
Thc Douglaa Fir trcer bcrc rhown are six to reven fect in diameter and 'XE to 25ll feet high, cornparcd with the 125 fcet of thc tcn rtory buildingr. Thcy arc irrobably 500 to 7ll0 ycrrr old, and if alIowed to rtand uaditturbed in-thc original forcgt migf,t Lrve become part of thc_ one pcr ceut attaining r diamctcr of tcn fcct or Eor_Freprcaenting a foot to the century.
Possibilitiec of Reforertation o n LoggedOff Landr of the Pacific Northwect.
Virgin timber quickly deteriorater when thc trer around it arc cut down; few large treer are eeen along thc railwayr or highwaye, and the few in the city are rapidly dicappcaring; but in a numbcr of tractc adjacent a young growth haa comc up in dence rtande which wilt makc good tinbcr. On tflct! cut 3O ycarr ago thc tre.r arc l0 to 12 incher in dianetcr, 75 fcet high and droppiug their lower limbr. Wf,ile on the land in and clorc to the city the sccond growth will probably be cut ovcr for ticr and pilins and be devotcd to igriJutture, it ie e viribli evidcnce of the rcforertation goiag on il thc irclated and mo-untainour rcgront.
Even in thc virgin for' eltr, firel, lightning, windatornrs-----and to a rnall crtent direaeeprcventa r largc proportion of thc timber fron attaining I great rize, and aftcr an everrge g?owth diamctcr of four feet, logging bccomer r:ather a coDacryt' tion of natunl re.ourcca than a warte, becaurc thc logged-off land will grow another crop in g) to 75 year.. It ir undcrrtood that after thc firrt necetrary burning of thc elarh, 6rcr murt be kept out, and that the growth will not naturrlly be rnorc than 30 incher in that tirnc, but it ie yct to be proved whcthcr thinning will or will not incrcue it.
