cross, as described alx)ve ; the second measurenient. taken at right angles 

 to this, should be entered above it in the record. 



In many instances the first live limb on a tree is not indicative of the 

 height of the base of the crown from the ground ; in such instances the 

 base of the crown should be taken and not the limb. This measure- 

 ment should be taken with the hypsomcter. except where the limb is 

 very close to the ground. 



Seedling Count Strips. — Strips five feet (or 8 links) in width should 

 be laid out with white cord across the major dimension of each perma- 

 nent sample plot, and all the young trees of commercial species (below 

 4 inches d. b. h. ) counted and recorded in height classes and accord- 

 ing to condition as provided on the standardized form. Such a strip 

 should include from i to 5 per cent of the total area (i/ioo to 1/20 of 

 an acre). These seedling count strips should be tied to some permanent 

 stake and so described. 



Personnel 



The crew may consist of three men. of whom one at least has tech- 

 nical training. The work on the plots should be divided and done in 

 the following order : 



1. Sun'eyiny. — Placing the large corner-posts. 



2. Measurements of Individual Trees. — One man shuuld jjuint tlic crosses and 

 numbers on the trees and do tlie cUameter taping or calipering, the second man 

 taking the height, and the man in charge writing tlie data as tliev are given to 

 him and such information as is required. 



3. Seedling Count. .Strips. — Small stakes arc to be set and the strip located 

 with reference to a corner-post or posts. 



4. The Reports. — The reports and additional notes in accordance with stanchird- 

 ized form should be made after all the other work on the plots (including the 

 photographing) has been done in tlie field. The preparation of the final report 

 may be done in the office. 



Photographs 



Tn making a ])h()tographic study of the plots at the time of measure- 

 ment it must be midcrstood that these photographs aim to show at least 

 three things: (i ) A general view of the plot to show the character of 

 the forest; (2) a series of photographs to show height growth and till- 

 ing in of crown cover of a representative detailed portion of the plot. 

 and (3) a series to show the progressive changes on the seedling strip. 

 In order to get this from the exact point, each time the camera might 

 be centered over a i)ermantnt marked objcit and oiitiitcd.
