PROCEEDINGS OF THE FARMERS' CLUB, 303 



" The orchard that I wish to try on is one that we have re- 

 cently purchased, is seeded, and will soon be used up by the lice, 

 if the cultivation is not changed and the lice removed." 



Prof. Mapes. — The best thing in the world is to wash the trees 

 with a saturated solution of sal soda. Heat one pound of sal 

 soda red hot, and dissolve it in a gallon of water. Apply it with 

 any sort of a mop or brush. This is the only thing that I have 

 ever used that was an effectual remedy for bark lice and other 

 insects. 



Mr. Carpenter said a potash wash answered the same purpose 

 on his trees — a pound of potash to one gallon of water. I have 

 tried the sal soda, and prefer the potash wash. 



Prof. Mapes. — I have frequently injured tender trees by potash, 

 and I have never seen any harm from the sal soda. It won't in- 

 jure the most tender plants. 



Mr. Carpenter said that the potash does kill leaves, but does 

 not hurt the boles or limbs of the trees. 



SUJ.PHUR FOR TREES. 



Mr. Carpenter stated that a friend of his has received very bene- 

 ficial results from the application of sulphur. Peach trees badly 

 affected by the peach tree worm, were entirely cured by sulphur. 

 The apple tree borers were also eradicated by a pint of sulphur 

 to the root of a tree. 



Dr. Trimble. — The peach worm is not a borer of the wood — it 

 works under the bark. The apple tree borer works into the body 

 of the tree, where it could not be reached by sulphur. 



A NEW GRAIN MILL. 



Prof. Mapes. — I want to speak of a new principle in grinding 

 grain, lately invented. There is no rubbing process, as between 

 the mill-stones. I have tried this new mill with various kinds of 

 grain, and the effect is wonderful. The effect is produced by no 

 rubbing or grinding, for there are no rubbing surfaces between 

 which the grain can be ground. The grain is reduced to fine- 

 ness, by the force of great speed of an armed wheel inside an iron 

 case. The wheat is divested of the bran and separated from the 

 flour. With five horse power, Prof. Mapes thinks more grain can 

 be ground than with forty horse power, applied to burr stones, 

 and that it will make more and better flour. The same mill 

 grinds the hardest substances, such as gold quartz. The mills, 

 as now about being made, will be sold at $300 each.
