produced either from over-ripening-, or £iom age and 

 excessive liearing. Now, if the curl proceeds from 

 over ripening-, mountain seed will be safe from this 

 ■disease, because vegetation on elevated grounds will 

 be sooner stopped by frost than in low situations — 

 it follows, therefore, that potatoes for seed should 

 be planted late. And to prevent the ill effects of 

 ag-e, frequent change of seed is most necessary ; and 

 fresh seed should be procured from potatoes that have 

 been planted on a different soil, as, from poor to rich, 

 and fiom clay to sand lands. The coarser the potato, 

 the less liable to (hsease, it will stand longer upon 

 the same lands without change and without renewing 

 the seed. — The varieties of potatoes are endless, as 

 vou will find by raising- every j'ear from seed, which 

 is produced from the fruit of the flowers. 



As to the mode of applying manure for your po- 

 tatoes, I think it shotdd be laid under the potato, 

 jiarticularly in wet lands, because, by so doing you 

 raise the roots above the level of the furrows at each 

 side of the drills, and of course preserve them from 

 rotting at the end of a wet season. In very dr^ soils, 

 where the moisture escape too fast, compost, such as 

 that of lime and clay, may perhaps be more advanta- 

 geously thrown over the seed. Ground which JutJS 

 been recently limed even in a very light degree, will, 

 with the addition of dung, produce the largest and 

 best crops of potatoes. 



The manner of moulding potatoes sliould be as fol- 

 lows : — As soon as the stems are three or four inches 

 over ground, an exj)osing plough should be run as 

 closely as possible to the roots, in order to loosen the 

 clay which it throws from them into the middie of 

 the furrows. After this operation, weeding is exe- 

 cuted quickly and effectually, either by the hand or by 

 a garden hoe. After the weeds become withered, 

 draw a scufHer, or small harrow, through the furrows, 

 in order to pulverize and clean the eai'th Ixifore it is 

 ^ain thrown up to the plants. The next -UiouJdin^
