Territory have been sent to this division. As will be seen, they arc 

 all extremely rieh in albuminoids with the exception of that grown in 

 Pembina. One specimen contains 18.03 per cent, of albuminoids, and 

 the ten together average over 15 per cent.

The wheat containing 18.03 per cent, of albumiuoids is the richest 

 which has yet been analyzed in the United States. It was grown in 

 La Moure County by Sykes & Hughes, and is, of course, a spring variety. 

 It would be interesting to observe the composition of a winter wheat 

 grown on that soil. 



Of winter varieties only one specimen has been obtained from the 

 Territory. This, in comparison with a spring wheat from the same 

 source, shows that the peculiarities are without doubt due, as has been 

 already mentioned in the case of Ohio and Minnesota, to a ditference in 

 the amount of starch, stored in the grain. 

 The size or weight per hundred grains of the two specimens was —

the latter being in inverse proportion to the former, so that if the 

 winter wheat were supposed to be diminished in size at the expense of 

 its starch the relative percentage of nitrogen would rise to a point near 

 that usually found in spring wheats. The spring wheats may, therefore, 

 be regarded as richer in nitrogen, owing, at least to a great extent, to 

 their inability to fill out the grain with starch to a size corresponding 

 with winter grain. 



COLORADO. 



In a previous report the analyses were published of a large number of 

 wheats from Colorado, grown during the years 1881 and 1882, by Prof. 

 A. E. Blount, of the Agricultural College at Fort Collins. The average 

 composition for each year was as follows :
