Page 1237, author’s emendation: In Table I in the caption “Number of seedlings remaining in 1923, by 
species and year of origin," insert “per acre” after the word seedlings. In Table II the meaning is confused 
by the wording of the captions and the use of the word survival. The title of the table should read “ Per¬ 
centages of total number of seedlings present in different years under scattered and under piled and 
burned slash, all methods of cutting combined.” In the first column, the word “survival,” used six 
times, should be replaced by the word “count.” In the second and third primary headings the words 
“of survival" and “by species” should be eliminated. It will be seen that in any column the sum of the 
figures for scattered and piled and burned slash for a given year is 100 per cent. In other words, the per¬ 
centage of survival is not being discussed, but the percentage of the total number of each species ( 100 per 
cent) present at any count on all of the cut-over plots which occurs on the slash-scattered area and on the 
piled and burned area. 
Page 1238, line 5, the words “third year” at the end of the line should be replaced by the words “first 
three years.”
