October, '09] JOURNAL OF ECONOMIC ENTOMOLOGY 337 



abreast of modern discovery and practice, — but is this element really 

 the one most important to reach? It is able to take care of itself 

 and is in the minority. It is doubtful therefore whether work con- 

 ducted especially for this more intelligent and progressive element 

 really results in that "greatest good to the greatest number," which 

 is often accepted as a test of real utility. We take it that with many 

 of us the question of reaching the great mass of our constituents ef- 

 fectively, to show them that economic entomology really has something 

 of value to offer them, is a matter to which we could profitably give 

 attention, and upon which we would be justified in making consider- 

 able expenditures. 



And let us state emphatically that we would not advocate popular 

 demonstration work to the exclusion of investigation, — not at all. 

 Some of us are so favored with appropriations that we can carry on 

 both lines at once. Those of us who, like myself, are not so fortunate 

 might plan to set aside a few weeks of each year for work of this sort. 

 We are doing this in North Carolina and it is working well. 



On assuming the duties here some years ago the writer found that 

 very few fruit-growers were spraying their trees, even when known 

 to be infested with the San Jose scale, and spraying to control codling 

 moth was almost unknown. These men knew no such science as en- 

 tomology and acknowledged no indebtedness to its teachings. We 

 soon found that the bulletins circulated but little among our orchard- 

 ists and that the average man gives but little attention to such bul- 

 letins as he receives. 



W^e have taken up the spraying of apple trees with, poisoned Bor- 

 deaux as the line of work in which we could most certainly assure our 

 people of profitable returns for their labor, — also for the reason that 

 its results show up strikingly and convincingly, and is therefore a 

 sort of advertisement of itself. 



During 1908 we conducted apple-spraying demonstrations in five 

 different counties in the apple-growing section, one in each county. 

 The demonstrations were widely advertised in advance. The party 

 carried a bucket outfit, as used in small orchards, and a complete barrel 

 outfit with two leads of hose, extension rods, double nozzles, etc., such 

 as is the standard for small commercial orchards. Three or four trees 

 only were treated at each place, and one of these was sprayed on only 

 one side. The poisoned Bordeaux was made up in the presence of 

 the audience and then sprayed on the trees, every step being explained. 

 We used Paris Green as the poison for the reason that it is more avail- 

 able to the average man than arsenate of lead. This series of public 

 demonstrations was given during February before the buds began to
