Rural Engineering. 



The following project represents the first experimental work done by the De- 

 partment of Rural Engineering since its formal organization as a Station depart- 

 ment. 



Rural Engineering Project 1. "Testing Low Lift Pumps." 



Professor Gunness. 



This project is co-operative between the Cranberry Station and the Department of 

 Rural Engineering. It was made necessary by the fact that there has never been a 

 comprehensive study made of the large capacity, low lift pumps as used so largely in the 

 Massachusetts cranberry industry. The work occupied a large portion of the sum- 

 mer of 1922. Manuscript has been prepared and submitted for publication, the project 

 in its present form being therefore complete. 



Meteorological Studies. 



The work of the Station in this direction consists in part of the taking of data 

 at the home station as indicated by the following; and in part in the definite ap- 

 plication of meteorological data to certain definite agricultural problems, notably 

 that of cranberry bog management and secondly the relation of weather to insect 

 development. 



Meteorology Project. 



The recording day by day of meteorological phenomena, and the publishing of monthly 

 summaries for distribution to parties interested has been continued. The year just 

 closed was the thirty-fourth over which this work has continued. When combined 

 with the records taken by the late Professor Snell, the Station has an unbroken meteor- 

 ological record of eighty-seven years. Work of this kind becomes more and more valu- 

 able as such records accumulate. 



Entomology Project IL "Study of area of the late frosts as shown by insect 

 distribution." 



Professor Fernald. 



More light on this subject has been obtained during 1922. It will require many years 

 for completion, but takes annuallj^ only the time necessary to record the data obtained. 



Cranberry Station Project 3. "Weather observations with reference to frost 

 prediction." 



Professor Franklin. 



As in past years, reports were telegraphed daily to the district forecaster at Boston. 

 Further frost records were accumulated for study. Distribution of Station frost warn- 

 ings was continued with the financial aid of the Cranberry Growers' Association.
