amounted to approximately $1.33 per man per day. This comes 

 to from 50 cents to 75 cents per acre for the corn planter, and less 

 than 10 cents per acre for the broadcasting. 



Extremely poor results with the corn planter are reported from 

 an experiment station in Colorado. These contrast strongly with 

 the good results obtained at Roubaix in 1905. The total failure 

 caused by drought prevents any conclusion being drawn from the 

 1910 work. It seems reasonable, however, to suppose that any 

 method which places the seed in direct contact with the mineral 

 soil, and secures a slight covering, will be better than haphazard 

 scattering which leaves all the seed uncovered and many of them 

 in unfavorable situations with regard to the ground cover. 



No conclusion can be drawn from the work on the Black Hills 

 as to the relative advantages of spring and fall sowing, since it 

 has all been done in the spring, with the exception of that in 1910, 

 the results of which are of course unknown. Experiments in 

 District i seem to indicate that a heavy precentage of the seed 

 sown in the fall fails to survive the winter. Although fall sow- 

 ing is the natural method, yet nature is commonly much more 

 wasteful of her material than we can afford to be. It is certain 

 that seed will retain a higher degree of vitality if carefully stored 

 than it can when it is exposed to the elements all winter.
