the fact that the difference iu value over cost of prodnction per acre on manured and 

 uumauured land is $5.96, which is attributable to the use of the manure, which costs 

 $7 per acre, just three times the usual cost, and yet we find here the increase result- 

 ing from the use of the manure pays 85 per cent profit upon its cost.

 Stiuhj of the soils of the State (pp. 1G-2S). 



For the purpose of studying the needs of the various typical soils of the State, a 

 dozen sacks of the soil and subsoil from localities representing large areas of the 

 State were collected and subjected to chemical and plant analysis. Samples of both 

 soil and subsoil were furnished the chemist, the analyses of which will be found in 

 the report of Dr. N. T. Luptou, chemist, iu this bulletin. Bins were prepared 18 

 inches broad and wide and 12 inches deep, eight for each soil. In these the subsoil 

 was first deposited, and the box then filled with soil, thus restoring somewhat the 

 natural conditions. Different elements and combinations of elements of plant food 

 were applied to seven of these bins, theeight receiving nothing, as shown in the tab- 

 ular statements appended. A cotton plant was grown in each bin and careful ob- 

 servations made of their development and production. * * • The results show 

 very marked differences in the effect of the manures, and valuable suggestions are 

 made by them, but conclusions should not be drawn from a single experiment. 



The details of the experiment are given in tabular form. Especial 

 attention is called to tlie effects of "Thomas scoria" (basic slag). 



Feeding pigs for pork production (pp. 29-31). 



Six Essex pigs, twelve to fourteen months old, that had grown fat upon field peas, 

 ground peas, and sweet potatoes, gleaned from the fields, were put into separate pens 

 on the 17th of December, 1888, and each given as much corn as he would eat as a 

 preparatory period to detect individual peculiarities, and to learn accurately the 

 producing power of whole corn fed wet. The pigs were already fat enough when put 

 up, and by the second period, in which each was fed differently, as shown in the 

 accompanying tabulated statement, were excessively fat. This being true, their 

 capacity for laying on additional fat was reduced. The gradually diminishing ratio 

 of increase from the first to the last period indicates that the profits of feeding dimin- 

 ish with increased fatness. * » * The condition of the pigs, when fed upon these 

 products, renders [necessary] a repetition of the experiment upon pigs not so far ad- 

 vanced in fatness. 



The details of the experiment are given in tabular form.
