it is highly important to operate when the sap is down, 

 or just completing its downward course. 



Having decided on the season and dissolved the 

 poison, we are ready to ''frill" the trees. By "frill- 

 ing" is meant a succession of downward axe cuts com- 

 pletely around the tree, each cut well overlapping the 

 adjoining ones, so as to leave no unsevered section of 

 bark up which the sap can flow. There is no doubt 

 that "frilling" alone would kill timber if allowed time, 

 but the poison does it in a fraction of the time ; in fact, 

 trees have been killed in a few days. These cuts must 

 be through the bark and well into the wood proper, 

 and as close down to the ground level as is convenient 

 to cut them consistent with the shape of the tree, say, 

 from six to ten inches up. 



For trees of four feet diameter, about a quart of so- 

 lution is poured into this frilling, right around the tree, 

 using an old teapot, or kettle, as the spout makes pour- 

 ing easy, and less is wasted by spilling needlesly round 

 about. Smaller trees naturally need less solution. Sap- 

 plings may be cut off low down, and with a swab-stick 

 the solution may be dabbed on to kill and prevent suck- 

 ering. 



It is very important that this frilling and the apply- 

 ing of the poison be consistently and thoroughly carried 

 out, and not in any way slighted if good results are to 

 be looked for. 



There need be no fear about stock being poisoned by 

 eating the fallen or dead leaves from poisoned trees; 

 for when the comparatively small quantity of solution 

 used is considered the likelihood of the leaves absorb- 

 ing any free arsenic is very remote. Nor is there much
