" Professor Lazeuby gave the result of experiments with the ef- 

 fects of pollen on the strawberry. He showed that in some sea- 

 sons pistillate strawberries are influenced by the pollen of the varieties 

 applied. A. J. Fuller concurred in this opinion, and the question 

 was nearly decided to the satisfaction of all present, that it was 

 possible to affect the flavor, size and form of the strawberry by the 

 application of pollen to the pistillate varieties. Yet it was not 

 claimed that the effect would be noticeable to the casual observer 

 in all cases, or might not be of sufficient importance to be adopted 

 by the market grower. Mr. Lazenby found that the Crescent 

 strawberry, growing alone under a glass, would produce no berries 

 when not fertilized. 



" Professor A. J. Cook, of Michigan, delivered an illustrated lec- 

 ture on Economic Etornology. It is known that the damage 

 done by insects last year was two millions of dollars, and the un- 

 known damage was probably as much more. The number of 

 species of destructive insects is increasing every year, and the war- 

 ing against them has become more important. Many of these in- 

 sects are formidable for the reason that they have no bird foes in 

 this country. An insect changes its taste and habits, often leaving 

 one plant and attacking another. A few years ago California was 

 free from injurious insects, but now it is thoroughly infested. In- 

 sects have foes that often suppress their depredations. A know- 

 ledge of these foes is absolutely necessary to the farmer and fruit 

 grower, also B. knowledge of the habits and life of insects. Im- 

 ported insects are far more injurious than our native ones. They 

 seem to take a new lease of life in this country, and are more fero- 

 cious and persistent in their efforts. 



" One half pound of London purple to a barrel of water, or a 

 spoonful of Paris green to a barrel of water, is recommended for 

 spraying trees at the time when the blossoms are about to fall, to
