Lasts Twice 

 As Long 



TPiROUGH the microscope, a 

 spindle looks as rough as sand 

 paper. That's where the rub comes. 

 But the powdered mica in J\Iica 

 Axle Grease fills up this uneven- 

 ness, making a smoother, cooler 

 bearing. That's why Mica does bet- 

 ter work, and lasts twice as long.

acid (PiiOb), 100 pounds; potash (K2O), 

 150 pounds; lime, 1,000 pounds; manure, 

 12 tons. 



"In Table II is given the yields ob- 

 tained from some of the above applica- 

 tions during the past five years. These 

 results were obtained from an experi- 

 ment with Baldwins, now twenty-four 

 years of age, located on a volusia silt 

 loam in Lawrence County, north of 

 Pittsburgh. On first inspection these 

 trees did not seem to be sulTcring espe- 

 cially from a lack of plant food, but 

 they had not been bearing satisfactorily 

 and their annual twig growth was aver- 

 aging only about an inch, with occa- 

 sional maximum growths of five or six 

 Inches. These rales of growth are con- 

 tinuing on the checks or unfertilized 

 plats, but they have been practically 

 triided on the plats receiving proper 

 fertilization. 



"In estimating the influence of the 

 treatments, the yields of the first year 



are excluded, because they can never be 

 materially affected by the application of 

 the first season. The yields, as shown 

 in Table II, are given in pounds per 

 plat, and also in bushels per acre, annu- 

 ally for the last four years. 



"In the first place it will be noted 

 that the average yiekls of the cheeks or 

 unfertilized plats have run fairly uni- 

 form, producing an average annual 

 yield of 174.2 bushels per acre during 

 the last four years. Lime alone (at the 

 rate of 1,000 pounds per acre annually) 

 has shown no improvement over the 

 average check, but as a matter of fact 

 it has averaged .S.H bushels per acre 

 less, a deficit that is doubtless largely 

 or wholly due to iiuideiilal causes and 

 natural lluctuations. The phosphate and 

 potash combination has alfected the 

 yield here rather dislinctly. This ma> 

 be due at least partly to a possible 

 advantage in location, as indicated by 

 Ihe fad that its adjacent check is the 



highest ]jroducer among them and is 

 averaging wilhin (il bushels of the phos- 

 ])hale-pi)lash treatment. The growth on 

 the latter plat, bowever, is nearly 3 per 

 cent less than lliat of the normal unfer- 

 tilized plat, and its general appearance 

 is not appreciably suijcrior to that of 

 the checks. It is evident, therefore, that 

 these trees are still vitally in need of 

 something, although it will be noted 

 that they are receiving the fertilization 

 connnonly advised for orchards, largely 

 on the basis of chemical analyses. 



"This need is being (piite thoroughly 

 met on the adjacent plat 6, which dilTers 

 from number .5 only in the addition of 

 nitrogen. The mere addition of nitro- 

 gen in this case has more than tripled 

 the gain. Wherever nitrogen appears 

 in the treatments very large yields are 

 observed, and foliage and growth of the 

 trees are also very satisfactory, the 

 average gains in trunk girth ranging 

 from 25 to 90 per cent. 



"Flat 2, receiving nitrogen and phos- 

 prate only, at the present time shows 

 a better gain than number G, which 

 receives potash in addition. This is 

 directly connected with the almost 

 complete crop failure that occurred in 

 the latter plat this past season, and it is 

 also doubtless jjartly attributable again 

 to the natural fiuctuations in yield. It 

 shows, however, that no additional 

 potash is needed in this orchard, so far 

 as the yields are concerned. 



"Phosphates are next in importance 

 to nitrogen here, as indicated by the 

 42-busheI deficit that occurs on plat 3, 

 as compared with number (i, w^hen 

 phosphorus is omitted in the former, 

 and also by the high yields in plat 2. 

 Manure, as a result of the extra large 

 crop of 1912, when most of the other 

 plats were having an off season, is now 

 in the lead in this experiment, with the 

 tremendous average yield of 037 bushels 

 per acre annually for the past four 

 years. This gives an annual gain over 

 the check of 403 bushels per acre, which 

 is a very satisfactory exchange for 12 

 tons of manure, this benefit from 

 manure is doubtless largely due to its 

 nitrogen content." 



Fertility in Farm Produce. 



In Table III, taken in part from Dr. 

 Hopkins (Bulletin No. 123, Illinois Ex- 

 periment Stalion) is given a statement 

 of the composition and market value of 

 llie difierent plant foods carried by 

 some connnon crops. From 50 to !)5 per 

 cent of the fertilizing constituents of 

 food is recovered in the manure, de- 

 pending upon the kind of animal fed. 

 You can readily liguie what fertility 

 you are retaining on the farm by feed- 

 ing the products. 



Experiments by the United States De- 

 partment of Agriculture indicate that 

 with animals kept in stalls or pens 

 throughout the year and the manure 

 carefully saved, the approximate value 

 of the fertilizing constituents of the 

 manure produced by each horse or nude 

 annuallx is .'?27, by each head of cattle 

 .fl9, by each hog •'?12, by each sheep !?2. 

 These estimates are based on Ihe values
