day, and eventually the plants were ruined. Experiments made at 

 the Colorado Agricultural College not yet published, indicate that 

 kerosene emulsion may be used with success against this insect, but 

 it is impossible to get it appUed uniformly over a town full of httle 

 bean-patches in back yards. It seems practically impossible to 

 prevent numerous persons from raising enough bean-beetles to re- 

 plenish the neighborhood. Now this Epilachna, for reasons not clearly 

 understood, is of very restricted distribution. It abounds in the 

 vicinity of the mountains, from northern Colorado to southern New 

 Mexico. A short distance out on the plains it apparently ceases to be 

 a serious pest. It eats only Phaseolus, so far as I can find; soy beans 

 and other beans of different genera are untouched. It probably feeds 

 on po wild plant in the vicinity of Boulder. By entirely omitting the 

 cultivation of beans for a year or more, it could presumably be starved 

 out, and subsequently beans could be grown with safety. In the imme- 

 diate future, however, it is obviously indicated that beans should be 

 grown in those localities where the Epilachna is absent or a very minor 

 pest, and that in the Epilachna area the ground should be given to other 

 crops. 



Our experience with tomatoes has been very different. We got an 

 early variety from Burbank, and the crop of the three varieties grown 

 has been enormous. The season has been favorable, and up to the 

 date of writing (October 11) the crop has been continuous, owing to 

 the absence of frost. There have been no significant insect pests. 

 Toward the end of summer, as we had observed for many years past, 

 Heliothis ohsoleta is very abundant in Boulder. I have observed it as 

 early as July 27. I had thoughtlessly assumed that all these moths 

 were of local origin, but it is now evident that they migrate from the 

 south. Our tomatoes have been entirely free from the attacks of the 

 larvse, and our corn has been practically free, showing only light and 

 negligible infestation toward the end of the season. 



The tomato is not only edible as such, raw and cooked, but it may 

 be made the basis of excellent jam. Mrs. Cockerell finds that it is 

 possible to reduce the usual amount of sugar in the jam to a fourth, 

 replacing the rest by commercial syrup. By increasing the acreage 

 of tomatoes, in the region where these are not seriously injured by 

 insects, it is possible to produce a great amount of food, much of which 

 may be put up in the form of jam and preserves. It would, therefore, 

 seem to be a very important function of the Entomologists to ascertain 

 and designate the regions where tomatoes may thus be grown to the 

 greatest advantage. It may mean the addition of hundreds of tons of 

 food to our supplies in a single season. As with tomatoes, so with 

 other crops. The everbearing strawberry has been a delightful sur-
