away Mites from the fodder about to be used would also be worth con- 

 sideration ; for this Mite infestation has now been before the public 

 since at least 1886, and we do not seem to have made the least advance 

 by way of experiment towards lessening what amount of annoyance 

 stock may find in consumption of " mity " hay. 



Where the great masses of Mites are found congregated together 

 during their exit from stacks or lofts, one of the simplest ways of 

 getting rid of them would seem to be to shovel them up and destroy them. 

 To dig a hole and throw them in, and put a little tar on from time to 

 time during the operation, and a band of tar round the inside of the 

 hole, to keep them from crawling up the sides before the work was 

 completed, with some tar on the top, would be a very effectual measure. 

 Burning all rubbish in which the Mites congregated (after removal to 

 a safe distance from the stack), would also help. And in lofts where 

 infested hay has been stored, scalding down the floor with a good soft- 

 soap wash, and whitewashing the walls and all accessible parts, taking 

 care to get the applications into every cranny that can possibly be 

 reached, would do good. Where steam-power is at hand, throwing 

 jets with the help of a hose is a most excellent method for clearing 

 vermin, whether Mites, maggots, or others, from lofts or granaries 

 after presence of infested stores.
