These trees were exposed to the strong northerly winds. The i'igur'fes 

 probably ijidicate, only in a general way, the chances of trees on these 

 stocks being injured by high winds. Some of them can be set back without 

 much damage. It is significant that none of the trees on the semi-dwarf- 

 ing Mailing V nor on any of the so-called "standard" stocks suffered injury, 

 Mailing IX is not advocated for commercial orchards, and wherever it is 

 used in backyard plantings, we have recommended some support for the trees. 

 Me have never recommended Mailing III, 



It is unfortunate that trees on Mailing IV suffered so badly. Many 

 of the damaged trees were broken at the point of union, and so are a total 

 loss. In many respects this is one of the best semi-dwarfing stocks, but 

 if the trees aro to suffer like this just when they are ready to begin to 

 bear, it puts a black mark against this stock. 



This orchard was exposed to an unusually severe test. In the 1938 

 hurricane our few trees on Mailing IV suffered no worse than others, but 

 they were less exposed to the wind than were the trees mentioned in this 

 report. Me need further observations before condemning Mailing IV, but it 

 looks bad for it now.

BUD SPORTS OF MCINTOSH 



We have growing in our experimental orchards about 20 strains or bud 

 sports of Mcintosh each propagated from a known Mcintosh tree. One is from 

 a tree of about average color, two are from trees which bore striped apples 

 and the others are from trees selected because of real or supposed superior- 

 ity of color. Seven of these strains have fruited, including the "average" 

 strain; neither of the "striped" strains have yet fruited. There seem to 

 be rather small differences in color. The "average" strain is a little in- 

 ferior to most of the others and two of the strains seem a little superior 

 but it will require further study before we are able to say positively 

 which is the best, A strain of superior color may be inferior in other 

 respects such as vigor, productiveness, etc. An experiment is under way 

 which will show whether or not there are differences, other than color, 

 among seven of these strains,

COIITROLLING RATS AND MICE VflTH METHYL BROMIDE IN APPLE COLD STORAGES 



From fumigation tests with methyl bromide run last May and again dur- 

 ing October at the Massachusetts State College in cooperation with Lawrence 

 Southwick, Research Assistant, Pomology Department it was found that this 

 material is very effective in killing rodents without any observable injury 

 to, or effect on apples. Methyl bromide was tested on both mature fruit 

 respiring relatively slowly and freshly picked fruit. A good dosage seems 

 to be either ^ pound per 1000 cubic feet of storage space for a 4-hour 

 period qr ■§• pound for a 2-hour period. Since methyl bromide is injurious
