Miiiiy (lift'iculrics were ('.\i»;'riciicc(l in trving to kccj) ants 

 wa.v tVdiii rho bees, before tbeir aversion tor axle grease was 

 li^i'dvcrcd. Abont ten years ago bives in some ])laees were 

 n])])oi'te(l ii]»on ])osts to]' tbe- easy ai)i)li(*al ion of ant-i)oison, 

 vliile other a])iaries were ])rot('('t(Ml by I ins of water, as illns- 

 rateJ ity Dr. Pbillips." IJorb nieiliods bad to be discai'ded, 

 ecause of tlie necessity of frecinent rdiewals, wbieb nuub' the 

 ost ])rohibitive. Tanglefoot, also, ])roved worthless, from the 

 act that the ants wonld bridge ox-ei- it, in one night, with bits 

 f rubbish. Axle grease, on tbe otli( r band, appears to bo very 

 listastefid to them, and tliey stay away fi'om it. This snb- 

 itanee also has the ad\antage of being rather ])ermanent, last- 

 ug for two or more months. Hence, a couple of a])])lications 

 ire all that are required to carry the hees safely through the 

 vet-season; and the balance of the year they require no pro- 

 ection. 



For Itarriers, indoors, axle grease is hardly suitable, but the 

 veil-known bi-chloride-of-mercury band is equally effective, if 

 cept dry. Xarrow lamp-wicks serve best for this purpose. 

 They are soaked in a saturated solution of the poison, and 

 nmg up to dry, before pinning al)Out the legs of the furniture, 

 tc. 



What appears to be a most effective remedy has recently 

 )een nsed""'^ by Mr. Arthur Gibson, of the I)e])artment of 

 Vgrienlture, at Ottawa, Canada, hut I have not had time to 

 ry it u])on our ants. It consists in simply dusting sodium 

 hioride in the places frequented by the ants, and they sodu 

 isa])pear. This chemical has been reconimendedf for the 

 lestruction of cockroaches, bnt Mr. Gibson's article would 

 ii'licate that the ants are simply driven away by it.
