Of the other cited lusus, that called flabellata, the fan fir, is 

 quite frequent, in which all side branches lie in one plane with 

 the stem, so that the whole tree looks like a branch. Such 

 usually show near the base a curvature or thickening of the 

 stem, which leads to the suspicion that at that place an original 

 end shoot was killed, and it is really an erected side branch we 

 have to deal with. By and by this character is lost and a regular 

 tree developed. The author, therefore, thinks this should not 

 he considered as a lusus, but a growth form. He advises careful 

 watching of the lusus, protecting the species by freeing from over- 

 growing neighbors.

Munger has been observing the effect of 



Douglas Fir dry winds upon the leaves of Douglas fir in 



Leaves and the vicinity of Portland, Oregon. In March 



Chinook Winds and April, when the Chinooks come down 



the Columbia Canyon, the leaves of the fir 

 on easterly exposures turn brown. The injury is sometimes so 

 striking as to give the impression that all the timber is dying. 

 The year-old twigs are often killed, but as a whole the affected 

 trees recover during the growing season. The coast form of the 

 tree is more susceptible to the injury than the Rocky Mountain 

 form, which the fir east of the Cascades resembles, so the effect
