ware dealers exhibited window displays of spray outfits, etc., during 
spray week. Posters, tetter stuffers, and stamps on letters from the 
various departments of the college, announcing the campaign, also 
gave much publicity to the movement. For the agents, both men and 
women, making the best record during the week spray pump outfits 
were offered as prizes. 
The campaign was opened on Sunday when the various ministers 
of the state used an outline sermon prepared by ministers of the respec¬ 
tive denominations, which contained some reference to the campaign. 
In a systematic way spraying demonstrations and meetings were held 
in every community of each county of the state during the week under 
the direction of the county agent or his assistants. A chart was used 
at each demonstration discussing the fundamental principles of spray¬ 
ing and spraying operations, and some county official was usually 
present who made an address. A specialist was also on hand at a 
number of the meetings and demonstrations. 
The results accomplished from this first campaign were amazing. 
Spray pumps could be found in every community of the state either 
owned by individuals or community clubs and each community had a 
decided knowledge of the San Jose scale, and means of controlling it. 
The scale infestation as a whole most certainly was materially de¬ 
creased throughout the state. The sale of spray pumps and equip¬ 
ment in the state of Mississippi by one of the largest pump manufac¬ 
turers in this country showed an increase of 37 per cent during 1918 
as compared with the previous year. There was a likewise material 
increase in the sale of insecticides in the state, and during 1918 they 
could be found in practically every town in the state where they had 
not been for sale heretofore. 
Such excellent results were obtained from the first campaign that it 
was decided to put on a follow-up campaign during the winter of 1918- 
19. Practically the same means of organizing were used in the second 
campaign as in the first, only the dates were changed to February 9-15. 
Louisiana had seen the value of such a movement, and decided to join 
us in our second campaign. The dates were moved forward so as to 
give the sister state sufficient time to organize. 
The second campaign was equally as successful in Mississippi as the 
first. One manufacturer reports an increased spray pump sale in Missis¬ 
sippi of 40| per cent during 1918-19 as compared with the previous year 
and 134 per cent increase over the sales in 1916-17, before the first cam¬ 
paign. Others report an increase of 50 per cent and better. One dealer 
of insecticides states that their sales are now a nice part of their business, 
whereas they were practically nothing prior to the first campaign. A 
well-known manufacturer of insecticides reports an increased sale since 
the campaigns from practically nothing to 85,000 per year.
