bid defiance to anatomy 1" If this language be logical, then Mr. 

 Smee's book is logical, and all his letters are logical : but if a know- 

 ledge of anatomy is necessary to the surgeon ; if the structure of a 

 watch should be known to the watchmaker; if the ingredients of beer 

 should be known to the brewer ; so is a knowledge of physiological 

 botany necessary to the writer on the nosology of plants; so is a 

 knowledge of entomology needful to those who detail the doings of 

 insects ; so is a knowledge of horticulture essential to those who take 

 the subject of cultivation. Let us recommend Mr. Smee to carry his 

 witticisms a step farther ; let him suggest to the public the advantage 

 of a galvanic wire drawn over the potatoes by a couple of Irishmen, 

 one at each side of the plantation ; and let him issue a polite circu- 

 lar to the vastators, begging them to come to the wire and be killed.

" Remarks on Double-cropping, as a Means of lessening the Risk of 

 Growing Potatoes. By John S. Enys, Esq." 



(Extracted from the 14th Annual Beport of the Royal Cornwall Polytechnic Society). 



" In consequence of the second failure of the potato crop, it is pro- 

 bable many persons will be deterred from planting their accustomed 

 quantity of potatoes ; and hence, exclusive of the anticipated conti- 

 nuation of the disease, a deficient supply from a less extent of land 

 planted with potatoes may be apprehended. 



" Under these circumstances no apology I trust will be deemed 

 necessary for bringing before this meeting a suggestion for lessening 

 the risk of a total loss, by growing potatoes in alternate rows with 

 another crop, with a view that in case of the occurrence of the potato 

 disease in 1847, the increased growth of the second crop may in 

 some degree compensate their loss. 



" The expectation of a greatly increased produce from double 

 crops has, I apprehend, been but seldom realized ; and the plan is 

 open to objection, firom the greater cost of hoeing, and trouble in se- 

 parating, the produce. 



" Market gardeners, however, often remove one of such crops for 

 consumption, leaving the other to stand as the principal crop. A 

 failure of alternate rows of potatoes, if planted in this mode with
