heart, or if artificial manures are employed. The 

 spraying may be omitted, though our experience is in 

 favour of continuing it. Digging is subject to altera- 

 tion. With harvest wages, when the potatoes are 

 dug green and picked up, and the different classes of 

 quality are kept separate, the cost of digging, without 

 the expense of carting to the station, may amount to 

 2 per acre. On the other hand, the cost of digging 

 a very light crop may fall as low as 18s. per acre. 

 Kent is, of course, not a fixed rate, but varies with 

 the quality of the land. The cost of seed varies 

 according to the popularity and supply of the variety 

 grown, and average price of potatoes in the market. 

 The price of potatoes varies considerably from year to 

 year, and while in some, seed of popular varieties may 

 not be worth more than 2 per ton, in others it 

 may be well worth 4 or 5 per ton. Seed of early 

 varieties, which are more liable to disease, and are 

 most often affected by frost, varies in price much more 

 widely than that of late kinds, and a difference of 

 several pounds per ton frequently occurs in the course 

 of a year. New varieties of great promise are much 

 more expensive, as, when first introduced, they often 

 fetch 70s. per cwt., though this falls rapidly to 10s. or 

 less as the stock gets more widely distributed. The 

 high prices are warranted, because the seed from these 

 varieties sells well in the following year.
