A model farm, W. J. Spillmax ( U. S. I><pt. Ayr. Yearbook 1903, j>j>. 363-370, ph. 

 2 i . — This is an account of the management of a 15-acre farm in southeastern Pennsyl- 

 vania. The farm raises all the roughage for 30 head of stock, 17 of which are milch 

 cows. During the first 7 years that the farm was in possession of the present owner 

 it paid a mortgage of $7,200. The author concludes that the most important lesson 

 to be learned from the achievements of this farmer is that by applying such methods 

 as were used, it is possible to cause land to yield twice or three times as much as the 

 present average from what are considered good methods. 



"The most important single feature of this farm, aside from the remarkably sys- 

 tematic way in which it is conducted, is the manner of handling the manure. The 

 fact that the stock are all stabled the year round makes it possible to save all the 

 manure, both liquid and solid, and apply it to the land. Again, the fact that it is 

 applied daily, as produced, insures that any leaching by rains shall carry the leached 

 materials into the soil, where it is wanted. How much plant food is lost from fer- 

 mentation after the manure is spread on the fields is not known. But the remark- 

 able yields of every portion of this farm would seem to indicate that this method of 

 handling manure is highly satisfactory. 



"That similar results as to yield of crops may be accomplished by the use of com- 

 mercial fertilizers, combined with crops grown expressly for the production of 

 humus, is shown by the experience of a number of farmers, particularly in the truck- 

 growing districts. It may, therefore, prove possible to develop almost any type of 

 farming to a point that will more than double present average yields if agricultural 

 science continues to develop as rapidly during the next quarter of a century as it has 

 during the last." 



The nation's farm surplus, G. K. Holmes ( U. S. Dept. Agr, Yearbook 1903, jip. 

 479-490). — A statistical review of the export trade of the United States is summarized 

 by the author as follows: 



"The vast total of exports is composed mostly of cotton, grain and grain products, 

 and meat and meat products, with places of much less although of large importance 

 taken by tobacco, live animals, oil cake and oil-cake meal, fruits and nuts, and vege- 

 table i ids. With attention concentrated upon three or four, or at most upon all these 

 eight classes of products as exports to the countries of the earth, it may be still further 

 concentrated upon the United Kingdom as receiving one-half of all this country's 

 exports of farm products, and, in a less degree, upon Germany, the recipient of one- 

 sixth, all other countries being individually of minor importance in thegeneral survey. 



"So it becomes easy to rind our principal competitors, which are, in meats and meat 

 products, Australasia, Argentina, and Canada, and Denmark in bacon; in live animals, 

 Argentina and Canada; in grain and grain products, Argentina, Russia, Canada, and
