EXPERIMENTS. EXTENSION 27 



The Timber Planting records should show the full history of 

 each plantation examined, as far as obtainable. In addition to the 

 data secured under each head, may be added remarks concerning 

 improved methods of management, suggested by present condi- 

 tions, which might be used to advantage. 



EXPERIMENTAL TREE PLANTING. 



During the spring of 1912, 45 species of trees, mostly foreign 

 to the state, were planted experimentally in the College nursery. 

 The stock consisted mainly of seedlings and comprised over 1,500 

 individual trees. Additional" nursery stock has been purchased for 

 further planting and consists mainly of such conifers as it is be- 

 lieved may prove valuable for ornamental and forest plantations 

 in this state. These trees are to be watched carefully during sev- 

 eral years to determine their hardiness and adaptability to this 

 climate. Observations will also be made concerning the best meth- 

 ods of cultivation, irrigation, and pruning of trees. 



CO-OPERATIVE BASKET WILLOW PLANTING. 



Basket willow growing in this country is becoming a matter 

 of considerable interest and several inquiries from persons living 

 in this state have been received concerning the possibilities of carry- 

 ing on this industry here. To test out this matter on a small scale, 

 the Forest Service has supplied a number of varieties of the com- 

 moner species of basket willows for experimental planting. These 

 have been set on the College land and certain varieties are already 

 showing excellent growth. It is believed that it will be possible 

 in another season to supply enough cuttings from our own holt to 

 establish a few small experimental plats on river bottom or other 

 wet land, in co-operation with farmers. 



EDUCATIONAL EXTENSION WORK. 



The lines of work of an educational nature that have been 

 carried on have consisted in the answering of correspondence in 

 relation to tree planting and other forestry matters. 



Several addresses have been delivered at farmers' institutes, 

 teachers' associations, and women's clubs upon various subjects 

 that pertain to forestry. 



The following is part of an address delivered before the An- 

 nual Meeting of The Colorado State Forestry Association in Den- 

 ver, February 15, 1912.
