position than swedes, but against it, when considering 

 the value of the crop, must be placed the turnip-tops, 

 which have a value for feeding not possessed by potato- 

 tops. 



The cost of producing a crop of potatoes and a 

 crop of swedes must be taken into consideration. 

 Without going into the details, experience shows that 

 it is easier to grow 25 tons of swedes than 12j tons of 

 potatoes ; or 40 tons than 20 tons of potatoes. Beyond 

 this the full feeding value of the potatoes is not ob- 

 tained, unless they are cooked, which involves extra 

 expense. In the case of sheep, large quantities of raw 

 potatoes produce scour; in pigs and horses indigestion. 



It is our personal experience to have had to feed 

 large quantities of potatoes, which have been injured in 

 one way or another, so as to spoil them for market but 

 not for feeding purposes. This experience confirms 

 the previous calculations, and we would more readily 

 feed two tons of swedes than one ton of potatoes. 

 We have gone into the subject of the relative feeding 

 values of the two crops, because results of a few 

 experiments are frequently taken as data to show the 

 exceptional value possessed by potatoes as a fodder 

 crop. Experience shows us that there is 110 special 

 advantage to be reaped by substituting potatoes for 

 swedes as a crop, nor is it more profitable to buy 

 potatoes at double the cost per ton that would be paid 

 for swedes at the same time. Our contention is that 

 remunerative potato culture is most likely to be ob- 

 tained by growing potatoes which, from their better
