84 THE STOCKFEEDER'S COMPANION 



oat averaged 4-43 per cent, albuminoids, and 40-45 

 per cent, fibre, while in the latter case the figures 

 were 2-81 per cent, and 47-12 per cent, respectively. 

 The explanation being that, in the cold, damp season of 

 1903 the straws of Potato oat as well as Storm King 

 were favourably affected in the fine dry climate of 

 Morayshire, but unfavourably affected in the moister 

 climate of Ross and Cromarty. 



Variety. Red wheats have, generally speaking, 

 greater " strength," i.e. are richer in gluten, than white 

 wheats. At the same time they are correspondingly 

 poorer in carbohydrates (starch). 



With oats the proportion of husk varies with the 

 variety. The husk of thin-" skinned " oats (Sandy 

 Newmarket, Potato, etc.) would not generally exceed 25 

 per cent, while thick-" skinned " varieties (Storm King 

 and Tartar King) may go well over 30 per cent, of husk. 



Grieg and Hendrick's experiments l showed that 

 the composition of the " dry " oat kernel varied in 

 different varieties ; e.g., Potato oat gave an average 

 analysis in three counties of 9-30 per cent, oil and 15-5 

 per cent, albuminoids, while Storm King was poorer 

 in oil (5-88 per cent.) but richer in albuminoids (16-51 

 per cent). 



Straws from different varieties of oats in the same 

 experiments also varied in composition. A striking 

 point brought out was that straw from Storm King 

 in Ross and Cromarty was lowest in fibre (44 per cent.), 

 as against 47-12 per cent in such a favourite oat straw 

 as the Potato. 



Manuring. The size of the crop is very much 

 increased by liberal manuring, owing to larger amounts 

 of mineral matter and nitrogen being taken up in solution
