Five experimental areas were sown in 1909, but with the excep- 

 tion of a portion of the Base Line area, included in the Redfern 

 plantation, they were complete failures. On the Base Line area, 

 three strips were sown with seed from the Coconino, Boise and 

 Medicine Bow Forests respectivel^^ The greater portion of each 

 of these strips is in the bottom of a grassy draw, and here the 

 germination was more than satisfactory. It is probable that the 

 rodents did not work among the grass to any great extent. 



In the spring of 1910 some 844 acres were sown at Redfern, 

 in the Bald Hills, and at Savoy. The extraordinary drought of 

 the season caused a total failure. Comparatively few seeds ger- 

 minated at Redfern, and these were practically all in the draws, 

 where the ground was comparatively moist in the early spring. 

 At the Bald Hills, no seedlings have yet been found. At Savoy, 

 a few germinated, but none of these at the usual time, in June or 

 July, but about the first of September, following a fall of two or 

 three inches of snow on August 24. 



In the fall of 1910, approximately 330 acres were sown near 

 Roubaix, in the vicinity of the previous experiments there. This 

 work was done by various different methods, and it is hoped that 

 the results will give some indication as to the best methods to be 

 followed in future work. 



No conclusions can be drawn from the work in the Black Hills 

 as to the technical advantages of the diff'erent methods. From the 

 point of cost, they rank as given below (the figures given are all 

 for Austrian Pine seed, at 35 cents per pound). 



The most expensive method yet tried is that of "careful seed- 

 spots," in which the sod is removed from an area about a foot 

 square, and the earth stirred up to a depth of four or five inches. 

 Five acres which were planted in this manner cost $31.66 per acre, 

 $25.60 of which went to the preparing of the spots. 



Next in cost are the "modified seed-spots", prepared with a 

 considerable degree of care, but with much less than the "'careful". 

 The cost of these is about $12 per acre, varying according to the 

 degree of care. One small block sown in the fall of 1910 cost 

 $11.32 per acre. 



These first two methods obviously introduce too great an initial 

 expense to be employed if any of the others can be made to give 

 satisfactory results.
