how to grow pea plants witli reasonable success in each experiment, we have not as 

 yet learned how to grow all species of j)lants in such a way as to insure normal 

 devclo]3ment. 



Meutiou is made of a series of experiments on this subject already 

 planned, in wliich it is proposed to grow the plants in an atmosphere 

 freed from nitrogen compounds. 



A greenhouse has been erected; a power air pump for forcing a current of air and 

 apparatus for washing the air so as to free it completely from all nitrogen com- 

 pounds, have been procured ; an air-tight case large enough to hold 30 pea plants 

 in separate pots or jars has been constructed, and preliminary experiments are now 

 in operation. If the winter's experience is successful, we hope to undertake the 

 experiments proper during the coming spring and summer.

PHOXIMATE COMPOSITION OF GOOD AND OF POOR CORN, C. D. 



Woods, B. S. (pjj. 26-28). — By good corn is meant the merchantable 

 ears, and by poor the soft ears and nubbins. 



In 1889 samples of good and of poor corn were taken from five and in 1890 from 

 four field experiments. The varietj- grown was flint corn, and in 1889 the seed was 

 all from one source. * * * 



[The results of analyses of these sam^iles are tabulated.] 



The percentage of jirotein in poor corn exceeds that in good by an average of 1.5 

 j)er cent, rarying from a minimum of 0.75 per cent in Mr. Healej^'s experiment to 2,3 

 per cent in- Mr. Dean's. There is very little difference in the amouut of crude fiber 

 in the two grades of corn. The percentage of ash is 0.2 per cent greater in poor than 

 in good corn. 



There is an average of 0.4 per cent more fat or oil in the good than in the poor 

 corn. The x)ercentago of nitrogen-free extract in the good corn is increased by an 

 average of about 1.4 per cent. 



Fertilizing ingredients in crop and in roots of legumes, 

 C. D. Woods, B. S. (pp. 29-36). — This includes analyses with ref- 

 erence to fertilizing ingredients of several samples of cowpea 

 vines, soja beans (beans and vine), horse beans, vetch vines, clover, and 

 white, blue, and yellow lupines; a calculation of the amount of these
