ing. If the grazing can be stopped, experiments in fall planting of European 

 larch and Douglas fir will be tried this fall in Davis Park. 



Another line of experimental work which will be started this year is the 

 study of growth and yield of woodlots of quick growing and economic species, 

 particularly pure stands of second growth white pine on different types of 

 soil. This will be done by locating permanent sample plots of known size, 

 two together in each of the different conditions to be studied. These plots 

 will be marked by substantial corners. The amount of timber in cords or 

 board feet on each plot will be detei mined with great accuracy. One of the 

 two plots of each kind will be given such thinning or other treatment as seems 

 desirable in order to increase the yield and improve the condition while the 

 other is maintained in natural condition. Measurements will be taken each 

 year and the yields recorded together with all data such as amount of material 

 removed in thinnings, etc. After a few years the comparison of yields from 

 the paired plots will give figures of much value to foresters and owners of 

 woodlots. After plantations of other economic trees have been established 

 permanent sample plots will be Located in these also. 



Consultation with owners of woodlots and plantations of trees have been 

 made throughout the year and many tracts have been personally examined. 

 Because of the amount of time required in making these examinations, this 

 work cannot be greatly extended as a part of the Experiment Station work 

 until assistance in teaching is available. Eventually it would be desirable 

 to have much more of this extension and demonstration work handled from 

 the Station. 



There is great need in the State for published information on the treatment 

 and management of New Hampshire woodlots. It is desired to publish an 

 extension bulletin on this subject this year. 



REPORT OF THE EXPERIMENT STATION 



LIBRARY. 



MABEL HODGKIXS. 



The Library is still administered as a department of the College library 

 for the ordering, accessioning and cataloging of books; and, in addition, half 

 the time of one assistant is given to filing bulletins, checking periodicals re- 

 ceived and general work with the collections. Loose-leaf binders are being 

 used instead of pamphlet boxes for holding station bulletins in good order 

 until the volumes are ready for binding; and we hope very soon to get a fairly 

 complete set of Department of Agriculture publications bound for permanent 

 preservation.
