accompanied by deep trenching. Where the area to be dealt 

 with is not too great, trenching, if thoroughly done, is of 

 great service in getting rid of attack, for if the top spit 

 of land, with the maggot-cocoons or weevils in it, is turned 

 down, and the lowest spit laid on the top, then the working 

 part of the land (for a while at least) is purified from infestation. 

 Dressings of fresh field-soil are very useful in infested gardens. 



In planting seedlings, those that are much galled should be 

 rejected. Wood-ashes are said to be a good preventive for 

 attack on the roots, and dressings thrown on of sand, or 

 ashes, or dry earth, with parafiin added in the proportion of 

 one quart to a bushel of the dry material, would be very likely 

 to be of service in preventing the weevils going down for egg- 

 laying. 



The diseased growths known as "Club" in Cabbage, and as 

 "Anbury" or sometimes " Finger-and-Toe " in Turnips, con- 

 sisting of swollen masses and misformed bulbs, passing on in 

 bad cases to cracking and bursting of the surface followed by 

 putrefaction, are not caused by Gall-weevils, or by any other kind 

 of insect attacks, but by a kind of Slime Fungus, scientifically 

 the IHasmodiophora hrassica of Woronin. For information on 

 this infestation and means of prevention and remedy, the 

 reader is referred to observations by the late Dr. Augustus 

 Voelcker, in his paper on "Anbury," in the 20th vol. of the 

 * Journal of the Eoyal Agricultural Society ' ; also to a paper 

 on " Club-root," in ' Diseases of Field and Garden Crops,' by 

 Worthington G. Smith (Macmillan, London) ; and in my own 

 12tli ' Annual Report on Injurious Insects,' pp. 27 — 31, 1 give 

 condensed observations from the above authorities, with some 

 observations of my own, especially on the serviceableness of 

 gas-lime for prevention of this fungoid attack.

The damage done by this " Worm " or maggot is known as 

 " rust," from the peculiar reddish or rusty colour to which 

 the gnawed parts turn. 



The maggot is legless, white or yellowish, and shiny ; about 

 a quarter of an inch long, pointed at the head end, which is 

 furniohed within with a black horny apparatus of two curved
