The possibilities of agricultvire in Ohio, C. E. Thokne (Agr. Studenl. 17 

 (1911), No. o. pp. 7-9, S.'i, 35). — This article points out that now the free lands 

 of the Northwest are exhausted and the migratory movement which was 

 steadily westward for several years has practically reached its culmination, 

 the possibilities of agriculture in the East and Middle West are being consid- 

 ered more carefully than ever before. The water route advantages and the 

 several transcontinental railway systems in Ohio " offer facilities for transpor- 

 tation not excelled by any similar area in the world," and since more than one- 

 half its people live in large towns and cities and are largely occupied in manu- 

 facturing industries there are excellent local markets for farm produce.

While these figures show that there has been a general increase in the yield 

 it is recalled that the Ohio Station by a series of systematic experiments 

 showed that " on a tract of 40 acres, farmed in a 4-year rotation of corn, oats, 

 wheat, and clover, the yield of corn has been increased to a 5-year average of 

 70 shelled bushels per acre; that of oats to 55 bushels; that of wheat to 30^ 

 bushels, and that of hay to 4 tons." 



A system of tenant farming and its results, J. W. Froley and C. B. Smith 

 (U. S. Dept. Agr.. Farmers' Buh Ji37, pp. 20). — This bulletin discusses the fun- 

 damental principles of a system of tenant farming, showing its advantages and 

 disadvantages and why tenant farms often deteriorate. 



Special attention is dii'ected to a system of farming in eastern Maryland 

 organized by a merchant with no special knowledge of agriculture, a system 

 which has maintained for over 30 years yields sufficient to keep buildings, 

 fences, etc.. in a state of good repair and pay a net income of more than 5 per 

 cent to the estate, and at the same time give satisfactory profits to the tenants.
