 172. 16 p., 4 fig- 1919. — The experiments reported in this bulletin were conducted at the 

 North Platte Experimental Sub-Station in central Nebraska, and cover a ten year period, 

 1909 to 1918 inclusive. Four spring crops — wheat, oats, barley and emmer were grown at four 

 successive planting dates with 12 days intervals. Results are tabulated for each crop dur- 

 ing each year and the following conclusions are drawn: Early seedings produced the best 

 yields every year except two. The average yields of all crops were materially better from 

 early than from late seedings. There was less difference between early and late seedings 

 of barley and oats than of wheat and emmer. — Barley outyielded any other crop. On account 

 of the length of season in which barley can be successfully seeded, its high feeding value and 

 high yielding power, it should be more generally grown. — Lowest yields were obtained from 

 emmer. There seems little justification for growing this crop in the western part of the 

 State. — There was little difference between the values of spring wheat and early oats, either 

 as a feed or cash crop. — Weed growth is usually less troublesome in early, than in late seed- 

 ings. — T. A. Kiessclbach.

 scientific methods of gardening as a very practical basis for important phases of cultural 

 and useful education. — C. S. Gag r.
