TWENTY-XINTH FRUIT-GROWERS COXVEXTIOX.

with very satisfactory results. It is worth from four to five times as 

 much per ton as stable or corral manure. 



VICE-PRESIDENT :\rcIXTOSH. Members of the Convention, I 

 am gratified to be able to announce to you that we have by this paper 

 cleared up the entire program. 



SECRETARY ISAAC. Mr. Kearney's resolution relative to the 

 appointment of a committee of fifteen was adopted, and President 

 Cooper, before he was called home, informed me that he would make 

 the appointments later, when he had more time to consider the matter. 



VICE-PRESIDENT McINTOSH. I presume the appointments will 

 be announced through the press. 



SECRETARY ISAAC. They will be announced through the press. 



VICE-PRESIDENT McINTOSH. I requested President Cooper to 

 do this on account of his long acquaintance with the people of Cali- 

 fornia who are identified with the work along the lines pertaining to 

 agricultural and horticultural pursuits. 



MR. FAULKNER. May I ask a question in regard to the use of 

 the three elements most easily exhausted from the soil — nitrogen, phos- 

 phoric acid, and potash? May I ask whether it is proper to supply 

 each one of these three elements at different times of the year, as some 

 authorities contend, or to supply them all at one time? 



PROF. WOODBRIDGE. I have never known an authority to claim 

 that you could at one time put on your nitrogen, at another time your 

 phosphoric acid, and at another time your potash. The soil is built up 

 homogeneously, so to speak. In building it up all the elements go into 

 it simultaneously. Any different process would be like trying to build 

 a brick house by laying down three or four bricks, some sand on top of 

 that, some lime on top of that, and some water on top of that, the 

 result being that you would not have a very substantial wall. The soil 

 elements referred to are applied all together, perhaps with the excep- 

 tion of nitrogen. Nitrogen excites a large flow of sap and makes the 

 tree grow rank. Apply one hundred and fifty pounds of nitrate of 

 soda on an acre of grapevines at the right time of the year and it will 

 destroy any crop of grapes you would have had by causing the sap to 

 flow so freely that the vines would run into wood growth and leaf growth. 

 So with tomatoes. The only case wherein we find it of advantage to 

 apply any of the elements singly is the application of nitrogen in the 

 spring of the year, which makes the sap flow when the fruit is setting, 

 as it will make a succulent stem and therefore sets the fruit; but it is 

 dangerous to use too much of it, because only a rank growth of wood 

 and leaf will result.
