of domestic animals, the horse. The uses of the horse, calling for 
power and motion more or less combined, a new force auxiliary to 
these, crowds itself into the calculation. This is the nerve force. 
The nerve force is indicated by the volume of the brain and the 
temperament of the animal. In the production of the horse then, 
the farmer has to secure the best mechanical adjustment of bones, 
upon which, by relative contraction and expansion, is brought to 
bear the muscular force, which is stimulated by the nerve force, 
more or less active according to .temperament; all of which must be 
made to point precisely to the use for which the animal is intended. 
The cart-hor t se needs a very different bone structure from the roads¬ 
ter or race-horse. The cart-horse needs power more than motion. 
The roadster needs both, exercised however in harmony with just 
conceptions of style. The race-horse needs both in a pre-eminent 
degree, but he must also have that preponderating susceptibility to 
motion, which enables him to concentrate all his forces into it. 
Here is a nice problem for the farmer, and the nicety is augmented 
when he wants to add endurance to speed. It is an accurate com¬ 
bination of skill to produce the quarter nag. It is an achievement 
compatible only with the highest order of philosophical thought to 
produce the heat nag. These have never been produced in the same 
animal. The fastest speed and greatest endurance are incompatible. 
It is interdicted by organic law. The highest speed comes from an 
adapted anatomy, good nerve force, nervo-sanguine temperament, 
and a weight and volume of muscle for which under extreme exer¬ 
tion no pair of lungs could long continue to furnish arterial blood. 
The heat nag cannot carry the muscle essential to the quarter 
nag; his protracted motion has to come from sources of lighter 
power, from greater nerve force, longer but lighter muscle, acting 
upon a better average of bone structure, with less sanguine tempera¬ 
ment, which enables his lungs under continued effort to keep up 
a healthy circulation, freeing his extremities from venous blood. 
Allusion is made to these things to show that the farmer makes 
not a movement in the stable or stock-yard without risking a pen¬ 
alty for blind or stupid mistakes. Nor is he more secure in the 
field, the pasture, or meadow. How important to him then are the 
experiences of the past and the present, to be secured in no other 
way so completely as by organization. 
In contemplating the fruits of organization, in furnishing to
