Soon after Pearl Harbor,. Farmer Jones bought a new tractor with 

 all the latest improvements. It was a magnificent piece of machinery. He 

 was very careful while breaking it in and as a result has a machine that 

 is giving him wonderful service. Likev/ise, a little more care in starting 

 "green" and inexperienced help vrill preserve it for future use. It is not 

 a question of seeing whether or not the new man can "stand the gaff" the 

 first day by vrorking him from 5 a.m. to 6 p.m. with no time out between. 

 Break him in gradually; he will last longer and do a much better job even 

 as the tractor did. 



Hov; does a farmer train a colt? Does he completely harness the 

 young animal the first day and work him 10 to 12 hours plowing or harrow- 

 ing? Does he expect the colt to be able to do all types of farm work with- 

 out careful training? What happens if the young horse is forced to do 

 heavy work before he is physically fit to do so? The answers to these ques- 

 tions are, for the most part, obvious. 



Young and inexperienced help is very much like the frisky farm 

 colt; plenty of life and enthusiasm but short on knowledge and training, 

 in order to get the most out of either, the farmer must have patience and 

 self control. He should take time to teach the techniques of the various 

 jobs. He should remember that jobs v;hich have become practically second- 

 nature to him are entirely new to "green hands." 



Suddenly transfer a dairyman^ or a poultryman, or an orchardist, 

 or a vegetable grov/er from his agricultural environment to the work of a 

 radio broadcaster. Say to the farmer, "You are in charge of all the pro- 

 grams for the day. There are the controls, 'mike', etc. Now go to it." 

 ?/hat would bo the result? Probably disaster as far as the radio program 

 !• concerned. 



No, this inexperienced farm help "can't take it" at first; 

 neither can the tractor, nor the young colt, nor even the farmer as a 

 broadcaster.

YfliAT IS DN? 



One needs only to glimpse the chemistry of the so-called Dn ma- 

 terials to see how complex they are. It is fortunate that we can use them 

 effectively for insect control v/ithout knowing anything about their com- 

 position. There are at least six brands on the market, some intended for 

 dormant use, only, and some for summer use. All involve a "dinitro" radical, 

 Hence the term DN. The following brief statement prepared by A. I. Bourne 

 provides a little enlightenment for the chemically inclined: 



DN for Dormant Usei ' Elgetol - A sodium salt of Dinitro ortho cresol. 

 Active ingredients, Z^%. V«'ater, 66%, DN in oil - Dinitro-ortho- 

 cyclo-hexyl-phenol (D-n-o-c-h-p), 4^. Oil and emulsifier, 96%. 

 DN - D-n-o-c-h-p, 4:0fo. Inert carrier and emulsifier, 60^. 



DN for Summer Use; D-4 (dust) - Dicyclo hexylaraine salt of D-n-o-c-h-p, 

 1.7^. DN-111 ( spray j - Dicyclo hexylamine salt of D-n-o-c-h-p, 20^.
