direct and positive action of every element in it, without chance of 

 error or mistake, and one that can be applied of any strength desired, 

 to all kinds of foliage and under any conditions that may arise. 



We believe that the simple change of the conveyor from water 

 to lime dust in our present formula will accomplish this, and we re- 

 spectfully but earnestly call the attention of scientists and all others 

 to the record this simple change has made while yet in a crude state 

 of development, unaided by science, in proof of the faith that is in 

 us. 



By the simple change of the conveyor, we discard a useless, 

 expensive and dangerous element for one that is potent, cheap and 

 easily applied ; by the change, we add another good fungicide and 

 insecticide to the formula used alone ; our conveyor, lime, is a sure 

 remedy for leaf curl and other fungous diseases as well as some 

 classes of insects. In fact, as we progress with our work, we are 

 inclined more and more to give a great deal of credit to the free 

 use of lime dust to our trees, fruits, plants, vines and vegetables. 



By the change of conveyor, it enables us to add other good 

 elements to the formula, notably sulphur and tobacco dust, which 

 cannot be used in the wet process. On citrus fruits, lime and sulphur 

 have proven to be a sovereign remedy for red spider and rust mite. 

 Large orange orchards in Florida and southern California treated 

 by the above simple formula are entirely free from rust, every orange 

 being bright, and many of them fancy. On a single orchard of lOO 

 acres, the crop is worth $2,000 more than it would have been if 

 treated by the old method. We have also succeeded the past season 

 in combining sulphate of copper in powdered form with our 

 formula, holding the sulphate of copper in suspension indefinitely 

 until applied to the tree and fruit, and as moisture is furnished by 

 nature in the form of dew, gases of the air, etc., the Bordeaux mix- 

 ture is formed on the tree and fruit, instead of in the compounding 

 tank. Natural laws are thus brought to our aid, and nature never 

 makes an error. We thus get the direct and positive action of the 

 sulphate of copper, without any chemical changes until nature has 

 supplied the moisture to slowly produce them, and finally the inert 

 compounds are formed on the tree and fruit as in the compounding 

 tank — but not until the sulphate of copper has done its work. 



We thus have, by the simple change of a useless element in th 

 old method, been able to add to other strong elements and secure 

 the direct positive action of every element in the formula without 

 any chemical or inert compounds. The dry fungicide formula then 

 consists of lime, sulphur and sulphate of copper, three good elements,
