and 3. At the present time the apples on plot 1 take a higher 

 relative rank, and in all cases where the qnantity of fruit is not 

 excessive the apples on plot 1 are usually larger than on any 

 of the other plots. 



A number of tests of keeping quality have been made, and 

 in this respect the fruit has usually ranked in about the fol- 

 lowing order: plots 5, 4, 1, 2 and 3. The relatively low rank of 

 the fruit from plot 2 in keeping quality appears to be con- 

 nected with the fact that this fruit comes to maturity earlier 

 than that on the other manured or fertilized plots. It will be 

 noted that the fruit from plot 2 ranks highest in appearance. 

 This is due to its superiority in coloring. This in turn is un- 

 doubtedly connected with the fact that the fruit is somewhat 

 more mature. Such fruit might undoubtedly be kept if 

 promptly put into cold storage ; but in ordinary storage it is 

 considerably inferior to the somewhat less thoroughly ripened 

 fruit on the other manured plots. 



The fruit from plot 5 has almost invariably been much su- 

 perior in appearance to that produced on plots 1 or 4. Here 

 again there have been individual variations in the product of 

 the different trees of the same variety on all of the d liferent 

 plots. There has, however, been no doubt as to the fact that 

 on the whole the product of plot 5 has been considerably supe- 

 rior in color and general attractiveness as well as in firmness 

 of flesh to the product from plot 4 ; while the product from plot 

 1, which receives barnyard manure, ranks below either of the 

 others in the qualities just mentioned. In general, the fruit 

 produced on plot 5 shows a considerably brighter and clearer 

 color than that on either plots 4 or 1. There can be no doubt 

 that it would soil at a higher price in the general market than 

 either of the others, although the difference between plots 4 and 

 5 is considerably less than between plots 1 and 5. The product 

 of the unmanured plot, 3, shows good color and in some cases 

 is of fair size, but in general is too small to command the best 

 prices. 



The Results discussed. 



The most significant residt of the experiment is the superi- 

 ority of plot 5 as compared with plot 4. Reference to the tables 

 will show that the trees are much larger and that they produce
