AVE ATQUE VALE 



After forty-three years of exemplary devotion to duty, Dr. 

 Henry J. Franklin, director of research on insect problems at The 

 Cranberry Station, East Wareham, has retired in his seventieth 

 year. 



From the time of his appointment in 1909 to the present day, 

 the life histories of twenty of the serious bog insects have been 

 made known, and at least one satisfactory control measure has 

 been found for each. 



When heavy frost destroyed almost half the annual crop in 

 1917 and 1918, Entomologist Franklin bent the oars of meteoro- 

 logical study and developed a series of formulae for calculating 

 during the day the minimum bog temperatures for the coming 

 night. Now, in cooperation with the Cape God Cranberry 

 Growers' Association and the U. S. Weather Bureau at Boston, 

 frost hazards are figured daily at noon and in the evening in 

 April, May, June, September, and October. Warning of danger- 

 ous frosts is telephoned and radioed to the cranberry growers. 



The thoroughness of Dr. Frankhn's study on the relation of 

 weather to the size of crops and to the keeping quality of cran- 

 berries has made it possible to adjust the management of the bogs 

 to produce a maximum of choice berries and a minimum of poor 

 ones. Under Dr. FrankUn, the cranberry crop has increased 

 more than twofold, and is now the largest export crop of Massa- 

 chusetts. In the past fifteen years, the staif at The Cranberry 

 Station has likewise increased, rounding out the State's services 

 to the cranberry industry. 



As a living tribute to this grand old man of cranberry culture, 

 the cranberry growers have constructed and furnished an office 

 and study at The Cranberry Station. They are hopeful that he 

 will not only enjoy using the study for his particular interest, the 

 bumblebees, but that he will also remain available to them at the 

 scene of his life's work. 



God bless him with many happy years of retirement.
