plicity of the latter process and the superabundance of lime he must 

 necessarily use had saved him from serious consequences. We asked 

 him if he was going to continue the use of the dust, and he replied, 

 "Yes, I think the dust spray has come to stay." 



This is but a fair example of the conditions under which the dust 

 process has made for itself the most wonderful record in beneficial 

 results to the fruit grower that has ever been brought to their at- 

 tention. Pitted against the old system, fortified by long practice and 

 all that science and skill could do to perfect it, both as to appliances

and formulae, the newcomer has not lost a single patron, but stead- 

 ily forged ahead on its merits, and in the short space of three seasons 

 has spread into every state in the United States and four foreign 

 countries, and not a single valid objection has been urged against its 

 use. When we consider the amount of time, money and energy that 

 have been used to teach the fruit growers the proper and precise 

 method of making the liquid Bordeaux mixture, that bulletin after 

 bulletin has been published by the United States Agricultural De- 

 partment, as well as the various state experimental colleges, bearing 

 directly on the best methods of fighting insects and fungi, giving 

 every minute detail that was essential to success ; and that not a 

 single bulletin or line of direction that our scientific men and colleges 

 would vouch for has ever as yet been published as to dust spray- 

 ing, all the data obtainable for guidance in the premises coming from 

 the practical fruit growers in their orchards, both as to methods and 

 formulae, the record is astounding. By crude methods and, at first, 

 crude appliances, the practical growers demonstrated the superiority, 

 simplicity and effectiveness of the lime conveyor. It is well that
