Experiments in forestry, C. >S. Crandali. ( Colorado Sta. lipt. 1899, pp. S4, S5) . — 

 The station has continued experiments in forestry started in cooperation with the 

 Division of Forestry of this Department in 1896. On one of the forest plats nearly

 well as a protection for other plants, but to be of no other use, as they kill to the 

 ground each winter.

Investigations on -weeds, II. L. Bolley {North Dalfota Sfa. Rpt. 

 1899., pp. '2b-'2S). — A brief report is given of experiments conducted 

 in weed destruction, in which marked success was obtained when cop-

 to 50 gal. per acre. 



The author has begun an investigation of weed seeds planted at dif- 

 ferent depths, in which the seeds of a number of the more common 

 weeds were planted at depths varying from 1 to H» in. 



Studies have been made at various elevators and mills throughout 

 the State to determine what influence they may have as weed distrib- 

 uters. It was found that the following weed seeds occur quite abun- 

 dantly in wheat and are responsible for considerable lows not only in
