Bailey iu his work) did not go into scientific points, nor was the work 

 in any way compulsory. In 1885 the boys were shown the warbles, 

 told their history, and begged to bring what they could find; amongst 

 them, one pupil alone brought in 250, and in the followituj year, when 

 he examined his father's and his brother's stock (numbering 114 head 

 of cattle), he found no warbles, excepting on young cattle which had not 

 been dressed because they were out in the fields. 



So year by year the work continued. The boys examined the 

 cattle at the time when the maggots were beginning to be in a state to 

 remove, and brought them in to Mr. Bailey, who noted numbers and 

 details, and gave me the results yearly in tabulated form until the 

 pest was nearly stamped out. These gave in separate columns the 

 names of the finders, the number of stock examined, — ranging in the 

 table before me from a single cow up to eighty-six, — and also the 

 amount of warbles on cow, calf, or heifers. From these tables and 

 notes the steady and immediate drop in amount of warble-presence 

 where care was taken was clearly shown, and also the immediate 

 runniug-up of numbers where uncared-for cattle had been brought in, 

 or from some cause there had been difficulty iu giving the necessary 

 attention. 



Eelatively to this point, on April 13th, 1887, Mr. Bailey informed 

 me: — "Another lot of boys have examined and reported to me on 

 250 head of stock. The results agree with those I sent you. 



" Where the cattle were properly attended to last year by the warble- 

 maggots being squeezed out, or dressed with McDougall's smear or 

 cart-grease, there are scacely any maggots to be seen now; where, 

 however, this precaution has not been taken, the enemy is to be found 

 in full force." 



As examples of the former, Mr. Bailey mentioned two of the boys, 

 who had paid great attention to the matter in the previous year, and 

 had (at time of report) examined, respectively, one 58, the other 53 

 cows and heifers ; in the first case finding only one warble, in the other 

 only six. 



" On the other side, where remedies had not been applied, two 

 brothers removed 40 maggots this week from one stock, and their task 

 is not half done; another boy applied McDougall's smear to 70 

 warble-maggots. 



"It is not only on our large farms where so much energy is being 

 shown in an effort to stamp out this pest, but the sons of our cottagers 

 are equally active in the cause. These boys in a few years will be 

 our agricultural labourers, and I encourage them to examine and 

 report to me on their one cow and heifer. 



" Where the stock is free from the pest the boys tell me the cows 

 are milking unusually well this year." . ..." I have no hesitation in
