 Canning investigations. 



Progress in some of these investigations is handicapped by a 

 shortage of land. This condition is due primarily to the en- 

 croachment of buildings on the old Experiment Station grounds, 

 but in addition is due to the fact that land once used for 

 certain types of experiment is rendered useless for other kinds of 

 experiments for long periods of years. Therefore, while it is 

 true that several of the present field experiments had best be 

 brought to a close, yet the land involved will not become im- 

 mediately available for other investigations. It is therefore 

 hoped that the projects now in the hands of the trustees for 

 the purchase of the Brooks Farm and of the Tuxbury land will 

 receive the support of the Legislature. 



In this connection it should be stated that the time is coming 

 when the Experiment Station must branch out and undertake 

 thoroughgoing work in other sections of the State. A start in 

 this direction was made about ten years ago when the Cran- 

 berry Station was first organized. The success of this station
