or indirectly in the growing of crops, including particularly 

 fruit growers, entomologists, and plant pathologists, says the 

 department. Of course, the beekeeper does not want his 

 bees poisoned, but the loss of honey is only secondary in compari- 

 son with the loss from lack of cross-pollination of flowers. 

 In this respect, the beekeeper, the fruit grower, and in fact 

 everyone is benefited by bees. 



It is now generally admitted that in using arsenicals as a 

 control for the codling moth the best results are in nearly all 

 cases obtained by applying the first spray after most of the 

 petals have fallen, although in commercial orchards where 

 hundreds of acres of trees must be sprayed within a limited 

 time it is necessary to begin spraying early in order to finish 

 the work before the calyx cups close. 



Because the codling moth can be as well controlled by spraying 

 when 90 per cent of the petals have fallen, entomologists recom- 

 mend spraying at that time rather than during full bloom, 

 especially since it has been definitely proved that spraying when 

 trees are in full bloom is injurious to insect pollinators. 



Dr. C. D. Fretz of Sellersville, Pennsylvania, died suddenly 

 on August 17th at the age of 81 years. Dr. Fretz was well 

 known for his botanical work and had long been a member of 

 the Torrey Club. Some years ago he revised the Flora of Bucks 

 County, Pa., adding some three hundred species to those 

 previously listed. His herbarium of over 8,000 specimens was 

 donated to the Philadelphia Academy of Science. Dr. Fretz had 

 a large medical practice but retired from professional work 

 to become president of the Sellersville National Bank, a position 

 he held for twenty-three years. He was prominent in local 

 educational and religious affairs. 



In October a nation wide quarentine against five needled 

 pines went into effect in order to check the spread of blister 

 rust. No white pines can be shipped out of New York state. 

 No shipment can be made from an infected state to a non- 

 infected one. The quarentine also restricts the shipping of 

 currant and gooseberry plants, the intermediate hosts of the 

 rust, from areas where pine blister is found.
