NATURE'S DUAL SOVEREIGNTY 121 



more growth, or more rapid exchange, making heavier 

 demands on the external administration, or commis- 

 sary side of life, and more quickly exhausting the at- 

 tainable supplies. If they cannot be obtained, inter- 

 nal improvements will be of no avail. To meet these 

 new internal demands, the external administration must 

 invent, or find, new ways and means to supply them. 

 That is, there must be some improvement in the power 

 of capture, either by increasing the surface exposure 

 relative to volume, or by increasing the powers of dis- 

 covery, or locomotion, or orientation, or the power of 

 discrimination between good and evil. 



Locomotion is an expensive function. To be profit- 

 able, it must yield returns something over and above 

 the costs of transportation ; and the larger the body to 

 be moved, the greater the required velocity, and the 

 more that velocity must be changed, or regulated, the 

 more it costs. 



When such improvements in capture are made, and 

 the internal demands are for the moment satisfied, a 

 new state of equilibrium between the two systems will 

 be attained, only to be again upset by some new gain, 

 or loss, in supply or demand. 



Thus there is a perpetual see-saw between the com- 

 missary department of life, and the assimilation de- 

 partment. The system for the capture of supplies is 

 always under compulsion, as it were, to meet the new 

 demands of growth; and growth always uses its surplus 

 supplies to create new things, which themselves pro- 

 vide new ways and means of consumption and which 

 consequently create new demands. 



According to the Tightness of the federal adminis- 

 tration, a rise in the rate of exchange, or the volume of
