Although all these crops involved a financial loss owing to the 

 drought the dressing of potash in absence of farmyard manure 

 makes a considerable difference in reducing the loss. The 

 experiment indicates that wherever farmyard manure is running 

 short a dressing of potash should be given. 



No significant difference was revealed in these experiments 

 between sulphate of potash and sylvinite or French kainit, but 

 the season was not favourable for testing points of this nature.

Feeding Potatoes to Live Stock. — In several districts potatoes 

 have fallen to a price at vvhich it pays the growler to feed them 

 to live stock rather than sell them. Several correspondents have 

 asked for information on feeding potatoes, and a few practical 

 points are given here. 



Horses. — With regard to horses potatoes may be fed either 

 raw or cooked in amounts up to 17 lb. a day. 



Cows and Fattening Bullocks. — With, regard to cows or fatten- 

 ing bullocks, up to 28 lb. per head per day may be fed with 

 safety. These amounts represent the maximum. If fed in 

 excess of these quantities digestive disturbances arise. 



Pigs. — In the case of pigs the main question that arises is 

 whether the potatoes should be fed cooked or in a raw state. For 

 breeding stock and store stock, potatoes may be fed raw with 

 safety. Only in the case of small pigs is it necessary to cook 

 potatoes before feeding. 



The above remarks refer in all cases to potatoes of good 

 quality. Care should always be taken to avoid the " green- 

 ing " of potatoes, since green potatoes develop a bitter principle 

 which makes them very distasteful to stock. In the case of
