1908.] PUBLIC DOCUMENT— No. 33. 165 



horticultural division has consented to keep a phenological 

 record during the growing season for the use of this division, 

 and a copy is furnished the section director at Boston. 



The old thermometer shelter on the campus has 1)een re- 

 placed l3v a larger and more convenient one, and an under- 

 ground lead-covered cal)le placed for the purpose of providing 

 an electric light in the shelter. A second underground cable 

 is in place for connecting the tipping-bucket rain gauge with 

 the recording instrument in the tower. A specially designed 

 cover for the man-hole of the heating system, which is near 

 the rain gauge, has been secured. It is proposed to place the 

 rain ofausre on this cover in such a manner that the heat from 

 the man-hole will melt the snow which falls in the gauge, and 

 thus furnish a precise record of the time of the l^eginning and 

 endino; of snowstorms. 



A maximum thermometer of standard pattern is the only ad- 

 dition to the instruments made during the year. 



No change in the personnel of the observers has been made 

 during the year.
