apparent on inspecting the table is that it is impossible to grow 

 high-class barley by simply starving the plant. In each of the 

 series it will be seen that the barley showing the highest 

 average value, the best weight per bushel, the largest grains, 

 and the smallest proportion of tail corn, is that grown on Plots 

 4, where a complete manure containing both nitrogen and 

 minerals is supplied. It does not, however, follow that any

kind of manure will improve the quality of the barley. The 

 grain from the plot receiving farmyard manure every year, 

 despite the high weight per bushel, and the bold berry indicated 

 by the high weight of 100 grains, has yet a value considerably 

 below the average. Again, the use of nitrogen alone on Plot 

 1 A or 1 AA gives the lowest weight per bushel and the lowest 

 valuation of the whole series. It has already been seen that
