be, their vuvagcs lor many years have been very considerable. 

 Wheat and potatoes are the great objects of their attack : 

 wheat is cut through towards the crown of the root ; the pota- 

 toes are not sensibly affected in their growth, but when dry in 

 the autumn are found to be much hollowed. Grass-land I 

 have never seen injured here by any grub ; we have no old 

 meadow ; our general system is the convertible husbandry, — 

 three years ley, and then two or three course crops. The 

 ravages of these grubs are partial ; some fields are laid waste, 

 while others, within a quarter of a mile, remain perfectly free 

 from them ; again, they continue for some years in one place, 

 and then disappear.

61. IVireworm? — Another grub closely resembling the 

 enclosed, but in reality different, is found amongst the wire- 

 worms ; but I cannot at this moment procure a specimen : 

 these grubs appeared in a ley field which had been pared by a 

 breast-plough in February last. On moving the paring about 

 six weeks afterwards, in order to burn it, the grubs were found 

 collected in great numbers immediately under ; the opportunity 

 of destroying them was not lost, but several still appeared in 

 ploughing the ground. My principal object in addressing you 

 is to inquire, whether any effectual and economical method is 

 known of stopping the progress of this ravager ?

G2. Tm-nijJ-Jiy.—ln common with other parts of the coun- 

 try, we suffer severely from the turnip-fly {Haltica Netnorum.) 

 They are discovered easily enough in the turnip-grounds, but 

 unhappily we are not acquainted with any means of checking 

 them, with the exception of elder-bushes ; and these, however, 

 are very inefficient remedies for the evil.

[The writer of these remarks and queries particularly en- 

 joins non-publication ; we should however consider ourselves 

 unpardonable in withholding them. We hope our corre- 

 spondent will furnish us with a sheet-full of such notes for 

 every number ; — he will not only elicit information from 

 others, but he is himself giving information. We should 

 prefer publishing his name, but will not insist on that. — Ed.]
