which was later replaced by a permanent one. These were 

 made of Yellow Pine four inches square and about two and one- 

 half feet long. Much time was saved by securing them dressed 

 and sharpened ready to set, at a nearby sawmill. They were 

 driven into the ground a short distance and then surrounded 

 by -a mound of rocks. This precaution was taken because an 

 ordinary slender stake driven into the ground would soon topple 

 over under the great pressure of the deep snow. Each stake 

 was scribed S3/11 on one side facinsr outward from the Dlot 

 denoting that it was Silvics Plot Number 3, established in 1911. 

 The corner stakes were scribed on two surfaces each facing 

 away from the plot. The plots are numbered so that a definite 

 description may be filed in the office and as data is collected 

 that also may be added to the file for that particular plot. 



In marking this timber sale the principles of the shelter- 

 wood system were followed. The main points considered were 

 (1) to stock the cut-over land as fully as possible with 

 Jeffrey Pine and (2) to secure a second cut in thirty years. 

 All pine above twenty inches in diameter breast-high not 

 needed for seed and all merchantable fir above eighteen inches 

 was marked. Where the reproduction was poor the marking 

 was light, leaving a large number of seed trees, but where 

 reproduction was better the marking was heavier. Many of 

 the smaller sized White Fir were used for chute poles and 

 other snuall material used in exploitation. T'he utilization of 

 White Fir to as low a diameter limit as the trees are merchant- 

 able is advocated in order to reduce the proportion of this 

 species in future reproduction. No large openings were made 

 in the present stand since the exposed ground would be in 

 danger of reverting to chaparral or of becoming so dry 

 from excessive evaporation that no reproduction would 

 follow cutting. Where the stand of Jeffrey Pine was in- 

 sufficient to reseed thoroughly and protect the cut-over 

 area enough sound thrifty White Fir was left to form a fairly 

 even crown cover. Several of the larger White Fir which had 

 been marked were left by the loggers because they were found 

 to be defective. 



On this sale approximately two-third^ of the timber was 

 removed. The virgin stand on this twenty acre plot averaged 

 about 34,000 board feet per acre. The cut averaged 22,000
