THE IRRIGATION A GL 



quite a model one as any of the new fac- 

 tories recently constructed; and by the 

 fact that one year will be omitted, by no 

 means do the Company desire to have the 

 impression go out that they have sus- 

 pended business. The financial standing 

 of the Company is in first-class condition. 

 All who are familiar with the standing of 

 the owners of. the factory are aware that 

 they are not only fully able to carry through 

 the enterprise but one ten times its mag- 

 nitude. 



THE CANKER WORM. 

 The so called "measuring worms" that 

 are now stripping the leaves from apple 

 and elm in many parts of Ohio are canker 

 worms. Had they been taken in hand at 

 their first appearance they might have 

 been destroyed by spraying the trees with 

 a mixture of from 4 to 6 ounces of Paris 

 green with 4 to 6 pounds of slaked lime in 

 50 gallons of water, the lime being reduced 

 to a milk of lime and strained through a 

 fine wire seive, so as not to obstruct the 

 nozzle of the spray pump; but when the 

 canker worm has attained nearly its full 

 growth it is not so easily killed and Paris 

 green is not effective. At this stage, however, 

 it may be destroyed by spraying with 

 Swift's Arsenate of lead, Bowker's Arse- 

 nic lead or Bowker's Disparene, using 

 three ounces of the preparation to fifty 

 gallons of water. These mixtures will not 

 injure the foliage; when fully prepared 

 they have a milky white appearance, and 

 being nearly as thin as water they spray 

 readily, and they adhere for several weeks, 

 thereby avoiding the necessity for more 

 than a single application. They may be 

 obtained of Swift & Co., or Bowker Chemi- 

 cal Co., both of Boston, Mass. These are 

 merely proprietary forms of the standard 

 chemical compound, arsenate of lead. 



Recent experiments carried out by the 

 Entomological Department of the Ohio 

 Agricultural Experiment Station have 

 shown that within three days after appli- 

 cation of these mixtures to trees seriously 



overrun by canker worms, fully ninety per 

 cent of the worms were killed. 



If treatment is neglected the worms will 

 increase in numbers and by another season 

 will probably kill the trees. 



A complete illustrated description of the 

 canker worm, with its life history, is given 

 in Bulletin 68 of the Ohio Experiment 

 Station. 



ON ADVERTISING. 



The business may be old, the article 

 may be well established, but there is no 

 reason why the person who reads an ad- 

 vertisement for the first time should heed 

 it. To him the article is new; the busi- 

 ness is unknown; the advertiser a stranger. 



By repeating the advertisement time 

 after time, changing the points to make it 

 interesting reading and using different 

 display to attract attention, you ought in 

 time to be able to convince a reasonable 

 numbtr of these people that your goods 

 and prices are right. 



The first few advertisements may con- 

 vince some people. After that each ad- 

 vertisement will convince more people, for 

 it carries the influence of its predecessors.
