There* lo n st.-ong neconnity tMny for ' 

 on all thio v,'hon firrt raking up a woHtinr Flwi for any 

 foroot. Before drawing up any wording plan, there must 

 be lmown~~ 



Frenent narlcet conditions. 



Lines of transportation. 



Outleto for timber. 



1 robable changes din above three things. 



No worklnr plan whatever IB a fixed affair. It IB nub- 

 Joot to revision \vhonever changed conditions demand 

 and. to 3orce extent It should foresee changes. Tate tho 

 example given by Mr. Moore: Suppose p.n area now 

 supplying or able to supply a certain market, forming 

 nov, say, one working circle. Suppose that there IB the 

 possibility of a ruilroad belnc built in such a wny ae 

 to ]una by this nroa on the side furtherest from ite 

 present rcar):et. In this case certain whole blocks, or 

 certain lopping units of aorr^e blocks, would become 

 easily marketed by the railroad. The point IB that now, 

 iu alvanoo, there ought to bo foreseen, more or lees 

 o"f\otly, another arranpanent,- larger lodging units, 

 7^^3 f ibly conbinations of nor:e of the old logglnr unltn, 

 n.-t::lnr larger bloo'.ro, poasibly also making fewer blool:o f 

 to meet the new conditions. Honco there should now be 

 dec! Jed upon: 



: locks of logging wilts for the present :rar?'et, 

 Blocl's of different and larger logging unite 

 for use In case the possible railroad lo 

 really tuilt. 



Working plana can provide for accessible "' 

 of a for^nt the - : .art where reconnaissance wo:*?: can 

 be done very thoroughly in detail, and outline rough 

 rltxns for Inaccessible parts from the best iivailable 

 data, ouch as ocular estimates by Rangers, grazing naps, 

 any silvicultxiral information that can be pot, a:.', 

 later on, it ia probable that more Information can be 

 had, at least for a part of the procont Inacceosible 

 area. 



As roconnainsance work ic now being carried on 

 to rnich a largo or.tont on National Popestn its place 

 In a forest working plan should be noticed. It is 

 i ortant to understand it relation to the other parts 

 of the complete plan. The estimates made are not, of 

 course, the baaio for saleo of timber - that Is on the 

 aoal&d amount, what io actually got. Reconnaissance 

 la a .-jort of ntock-taking, soeewhat like the stock- 

 taking, of a r.ood store-'.cooper around the firnt of the
