to color, gentleness, non-swarming, and the like. Various strains of bees in the coun¬ 
tries concerned are being developed by selective breeding under qualified supervision. 
The following schedule of beekeeping meetings has been announced by the Ameri¬ 
can Honey Producers’ League: November 5-6, Portland, Oregon; November 6-8, 
Thermopolis, Wyoming; November 11-12, Denver, Colorado; November 14, Omaha, 
Nebraska; November 15, North Platte, Nebraska; November 18-19, South Dakota; 
November 20-21, Fargo, North Dakota; December 4-5, Madison, Wisconsin; 
December 9-10, Springfield Illinois; December 10-11, Lansing, Michigan; December 
15-16, St. Paul, Minnesota; December 17-18, Des Moines, Iowa, and December 19- 
20, Montana. In addition to the above meetings, various state beekeeping associ¬ 
ations will hold meetings as follows: January 8, Cambridge, Maryland; January 21- 
22, Pennsylvania; last week in January, Nashville, Tennessee; and February 5-6,

Notes on Medical Entomology 
The small species of predaceous fish, Gambusia a finis, imported recently from the 
States as a means of controlling mosquitoes, is reported by Mr. E. Hearle as thriving 
in the sulphur waters of Banff Springs. 
The occurrence of a case of yellow fever in Houston, Texas, during October caused 
some temporary excitement; however, prompt diagnosis and immediate isolation of 
the case prevented any further spread of the disease even in the presence of a fairly 
abundant supply of yellow fever mosquitoes, Aedts egypti. 
Miss Clara S. Ludlow of the Army Medical Museum, whose work on disease bear¬ 
ing mosquitoes has given her a distinguished place in the field of science, died in 
Washington, D. C., September 28, at the age of 70 years. Miss Ludlow discovered 
and described many new species of mosquitoes. 
In connection with the Mosquito Investigations at Banff, Alta., a shipment of 600 
fish of the species Gambusia ajfnis were sent to Air. Eric Hearle on July 25. They 
arrived in excellent condition. They were forwarded through the kindness of Mr. 
L. G. Lenert, Sanitary Engineer, Sacramento Board of Health, Sacramento, Cali¬ 
fornia. This experiment of introducing fish which are predaceous upon mosquito 
larvae, will be watched with interest. 
A few cases of dengue fever have occurred in Texas during the fall, but there has 
been no tendency for the malady to become widespread. The carrier of the disease, 
Aedes egypti, has been present in numbers rather above the average for this time of 
the year. It is probable that the large percentage of immunes is partially responsible 
for the comparative small number of cases this year. 
During July, W. E. Dove of the United States Bureau of Entomology, began in¬ 
vestigations of the human affliction known as “Larval Migrans,’’ with headquarters 
at Jacksonville, Florida. This work was undertaken at the urgent request of Dr.J. 
Lee Kirby-Smith, one of the leading dermatologists of the South, who has been 
familiar with this malady in his practice for the past fourteen years. The entomolog¬ 
ical aspects of the work are being conducted by Mr. Dove under the general super¬ 
vision of F. C. Bishopp. During the latter part of July a clinic was opened in Jack-
