result was from a single experiment, or to be more exact, they 

 have two experiments, which are both on the same soil. The 

 older of those experiments involved nothing but a comparison 

 of wood ashes against nothing. It was a wood-ash treatment 

 against no treatment. The other experiment involves the vari- 

 ous fertilization materials, but it is on young trees and really 

 includes only seven fruiting years. Also, if you will notice their 

 report, you will see that the total production involved in their 

 second experiment is much less than the average production of 

 almost any one of our ten experiments in a single year. The 

 cropping strain, therefore, has not yet reached their second group 

 of trees, hence no definite conclusions are justified on it as yet. 

 I didn't expect to make this comparison, but it is simply a mat- 

 ter of going into the figures for it, and it seems to be necessary 

 in order to get our data into the proper light. In other words, 

 the real experiment on fertilization in New York is not to be 

 compared in extent, yields, soil types, definiteness of results, or 

 in number and range of ages of trees, with the experiments in 

 Pennsylvania, and anyone who will look carefully into the ex- 

 act data involved cannot come to any other conclusion. 



Ques. You didn't state the amount of barn manure per acre? 



Ans. Twelve tons is what we have been using, but I don't 

 recommend more than eight. 



Ques. What about the cost of your fertilizer per acre? 



Ans. Fertilization of this sort runs between $10 and $12 

 per acre, depending on the market prices. Now that, as I say, 

 is a relatively rich fertilizer, and I would not recommend any- 

 body to put it on extensively until he has tried it out and found 

 out for his own situation whether it will give him as good results 

 as it has us. At the same time, notice that we have put these 

 fertilizers on, not in one place, but in several places, and have 

 obtained practically harmonious results. We do have one or 

 two experiments that as yet have shown no material gain from 

 fertilization, but we are not saying that fertilization is of no 

 •consecjuence in any orchard, simply because we have one or two 

 experiments that have failed to respond as yet. If we had no 

 experiments but these two, we would not consider ourselves in 

 a position to give advice on the subject of fertilization. It is 

 only when a man conducts an experiment that shows some- 

 thing definite that he is in a position to say much about it, it 

 seems to me.
