tain tables which are of value for comparison with our own analyses 

 and for filling out our knowledge of the plant in directions towards 

 which our investigations did not extend. 



EFFECT OF THICK AND THIN SOWING. 



The following tables give the chemical composition of the grain har- 

 vested after thick and thin sowing. The average weight per bushel in 

 both cases was 36.7 Ibs. All the analyses are calculated to 15 per cent, 

 of water, and the units of nutritive value, being calculated on a German 

 basis, are to us of only relative value.
