The early varieties of the potato do not 

 naturally produce seed ; but if their 

 tubers are removed as soon as they are 

 formed, these early varieties blossom and 

 bear seed as freely as the latter kinds, a 

 fact suggesting many experiments to the 

 cultivator of shy -blooming tuberous- 

 rooted flowers. Again, if the blossoms 

 of these later varieties are plucked off as 

 they appear, the weight of tubers pro- 

 duced will be very materially increased. 



EOOT-PKUNING, first adopted as a sys- 

 tematic practice by Mr. Errington, has 

 for its object a check to over-luxuriance. 

 This it does effectually, for such excess 

 of growth arises from the roots imbibing 

 too much, food. By pruning, and thus re- 

 ducing their number, therefore, we reduce 

 their imbibing power ; and it is found that 

 such pruning checks the production of 

 leaf-buds, and will cause any land of fruit- 

 tree to produce blossom-buds, provided 

 the tree is healthy, and that its barren- 

 ness arises from over-luxuriance. To 

 know what proportion of the roots to cut 

 away, we may suppose the trees thrown 

 into three classes. First, trees of mode- 

 rate luxuriance ; second, those which may 

 be termed robust ; third, those of gross 

 habit. To give a further idea, we would 

 say that the first class will make young 

 shoots, on an average, a foot in length; 

 those of the second two feet ; and the 

 third nearly, or quite, three feet: the 

 latter, indeed, frequently burst into latera] 

 or side-shoots from the young shoots of 

 the same season. 



From the first class, therefore, we 

 advise the cutting away about a sixth 

 part of the roots ; from the second class 

 a fourth part ; and from the third class 

 a third part. It must be borne in mind 

 that the extremities of the roots alon 

 should be cut off, for while we advocate 

 this mutilation, we equally advocate the 

 preservation of the surface roots by every 

 possible means ; nay, more than that, we 

 recommend their encouragement by extra 

 appliances of manure to the surface-soil
