the big fish eat the little was not true. In fact, I believe the time 

 will soon be here that the little fish will eat the big. At least, I do 

 not fear the, p onipetition of large orchard companies, but I do fear 

 the competition of the fellow who has only as many acres in culti- 

 vation as he can look after himself. i 



To summarize — -would say, the 



right 



man — -the right location — 



the right soil — -with all requirements strictly carried out, from the 

 planting of the tree to the marketing of the fruit, will find peach 

 culture as profitable as the culture of any other fruit. 



THE INFLUENCE OF FERTILIZATION AND OTHER FACTORS 

 UPON YIELD, COLOR, SIZE AND GROWTH IN APPLES 



By DR. J. P. STEWART, Experimental Pomologist, State College, Pa. 



The Pennsylvania Expeiiment Station has been conducting ex- 

 periments bearing upon the above subject during the past five years. 

 Altogether it has now in operation IS such experiments, involving 

 11 soil types and 3,(>G0 trees. In many respects, this series of ex- 

 periments is by far the most comprehensive of any similar series 

 thus far reported in America. In number of soil types; in the 

 number of treatments and checks ; in number, variety and range 

 of age of the trees; in duplications of the experiments of a given 

 type; in the amounts of fruit involved; and in the fact that the ex- 

 periments are distributed over the State and located as a rule in 

 regions generally recognized as being well adapted to apple produc- 

 tion — ^iu all these respects we believe that the Pennsylvania orchard 

 experiments enjoy distinct advantages over most previous efforts 

 to answer the questions involved. 



The results considered in the present paper are chiefly from 10 

 experiments, containing 2,219 bearing trees and involving 10 dif- 

 ferent soil types. Sorue of the general features of these experi- 

 ments are given in Table I :
