^'A HALF HOUR'S WORK TO THE ACRE SAVES THE CROP. 



Dirpxtions for use — Take two tablespoonfuls of the powder and 

 put it inl© a ten quart pail ; iLien add three quarts of lujiling water. 

 Fill the pail with potatoes cut in small [)ieces ; then All the pail with 

 water so as to cover the potatoes, and let stand over night or longer. 

 .Just before the potatoes come up, scatter the pieces over the ground. 

 This is enough for one acre. Price 50 cents." 



The millennium in potato raising would certainly be here, if by 

 "a half hour's labor to the acre" at a cost of "fifty cents" we could 

 "save the crop" from the ravages of the "potato bug." 



If potato beetles would all come out of the ground before the 

 .potato tops appear, and could be assembled to partake of the invit- 

 ing [feast spread for them, their destruction would be inevitable. 

 ^But as they prefer not to appear much before early potatoes are up, 

 and continue to emerge for a month or six weeks ; and as they will 

 rily a long wa}' in search of their favorite food and will not eat the 

 tubers when young tops are to be bad, there seems to be great difficulty 

 in fulfilling the necessaiy conditions. As it might be difficult to induce 

 the beetles to change their tastes and habits probabl}' the safest 

 and most economical plan would be to use the cheaper mixtures of 

 Paris Green and apply them in the ordinary way. This insecticide 

 was tried by two parties at Orono without any apparent "substantial 

 benefit", as the usual applications of Paris Green had to be made 

 later in the season.

Hammond's Slug Shot and Peroxide of Silicates will kill insects ef- 

 fectually. It is not a question of eflficiency, however, but one of relative 

 cost. For garden use where only a few pounds are needed many 

 would prefer to paj- a good price for an insecticide than to take the 

 trouble to prepare one. Most farmers who use considerable quan- 

 tity rather bu}' the plaster and Paris Green and mix them, than to 

 pay three or four dollars per hundred pounds to have it done for 

 'them.
