ping of the plot. In the establishment of permanent sample plots 

 everything should, of course, be made as permanent as* possible 

 and certainly its location should be definitely established. Obvi- 

 ously there is nothing permanent about wooden stakes such as 

 are often used. The writer has failed to locate small inconspic- 

 uous sample plots because of the disappearance of wooden bound- 

 ary stakes due to their consumption by forest fires, or to their 

 ruthless removal by disinterested persons who possibly made use 

 of them on the evening camp fire. A carefully established plot 

 is an investment of financial consideration, and more important 

 still, an investment of scientific and practical value not to be esti- 

 mated in money value. The location should, therefore, be per- 

 manent. 



Figure 2 shows a recent device for the permanent staking 

 of the smaller plots whose relocation is often difficult. From this 

 figure it will be noted that metallic pegs are driven at the outer 

 interception of the guide straps which determine the corner loca- 

 tions. These pegs are about 12 inches in length and 1 inch in 

 diameter. They are driven securely into the ground, leaving only 

 about 2 inches to protrude. The end of the protruding portion 

 is blunt so that grazing animals will not be injured should these 

 pegs be trampled upon. Further, in order to facilitate ready 

 location of the plot, larger wooden stakes are driven very close 

 to the metallic peg, so the latter is pretty well protected against 

 dislocation by grazing animals.
