and caring for them. In addition to this experiment the station is con- 

 ducting-, in cooperation with the Division of Forestr}- of this Depart- 

 ment, experiments in tree planting to ascertain the adaptability of the 

 principal economic species to the plains. 



The annual precipitation and temperatures are given for the State, 

 and a general statement made concerning the method of planting and 

 the condition of trees of each of the forest species. The planting, cul- 

 tivation, and irrigation was about the same as would be given an 

 orchard, except that the cultivation ceased with the sixth summer. 



The species tested are described at length, and their relative adapta- 

 ])ility and l)ehavior are described. Among the more promising trees 

 for that region (as shown by the results of 9 years' experiments), with 

 their height and circumference, are the following:

Fertilizers in the culture of osier willovrs, P.Wagner {V Engrais^ 

 lo (1900), iV^A 11, pp. 254, '^oo). — K series of experiments with various 

 fertilizers is reported, showing that the growth of osiers can be greatly 

 promoted by means of liberal manuring. The product was trebled by 

 the application of 1,650 lbs. of phosphatic slag and 550 lbs. of nitrate 

 of soda per acre. With the same amounts of slag and nitrate of soda 

 combined with 660 lbs. of a 40 per cent potash salt the yield was 

 quadrupled.
