ready reference all the information on the plot or series of plots 

 that would be necessary to enable a forester unfamiliar with the 

 plot or plots to carry on the work. It should include maps and 

 survey notes, directions for reaching the plot, and such summaries

 The instruments and methods used in each step of the work should 

 be noted with special care. In fact, it would be a good plan for 

 the writer of the establishment report to run through this manual 

 and wherever a choice of methods is presented explain which method 

 he chose and why.

 lowing outline that applies to the work done, explaining in detail 

 the methods used and giving all the descriptions called for in suf-
