THE MONTHLY BULLETIN. 



treated trees, and especially so in the case of those classed as "badly 

 gummed'' — bark killed over half around the trunk — where twenty- 

 three per cent of the trees treated wdth Bordeaux paste were cured 

 and only seven per cent on the check trees; seventy-one per cent of 

 the check trees were lost and only ten per cent of those on which 

 Bordeaux paste was applied. In the same table — Table No. 1 — plats 

 3 and 4, trees noted in plat 1 as "still gumming" were re-treated the 

 next year, August, 1913, using Bordeaux paste in both plats; those in 

 No. 2 were also treated with Bordeaux paste the second time in August, 

 1913. and the dead bark was cut out. The results — examination taking 

 place June 22, 1914 — shown here, with the exception of the "medium 

 gummed trees," are in favor of the Bordeaux paste. 



In the above cases all the trees were w^hat we term "old gums," or 

 those that had been gumming previous to our trials of Bordeaux paste, 

 and had received other treatments prior to July, 1912. In considera- 

 tion of this condition, and the fact that in previous treatments many 

 had been needlessly scored and cvit, the results are very satisfactory 

 and, as shown by the tables, warrant the continued use of Bordeaux 

 paste. 



The results of the treatment on "new gum trees," or those found 

 gumming after July 1, 1912, are shown in Table 3. The plats were 

 examined June 22, 1914. A few of these trees were not treated the 

 first year, but the number was so small that little difference is shown 

 at the end of the second year, and the trees may be considered wholly 

 as being treated wdth Bordeaux paste. The results here average up 

 about the same as those of Table No. 2, where the results of the two 

 years' treatment on "old gums" are summed up.
