and example a sound and sufficient morality ; to share in all the hopes 

 and aspirations of humanity ; to be foremost in practical reforms ; to 

 find what the instincts of mankind blindly search for by reference to 

 the character of God finally revealed in Christ, and to the hope of im- 

 mortality which His Resurrection brought to light ; to endeavor to 

 clear religion from the reproach of credulity, narrowness, timidity, and 

 bitter sectarian zeal ; these are, as our Master Himself assured us, the 

 only means of engendering in the hearts of men that moral quality 

 which we call Faith : for " he that is of the truth heaketh my 

 voice." 



In a future paper I hope to show, by reference to the facts of man's 

 nature, how this faith in immortality is being, and is to be, so far 

 wrought into his mind as to form a predisposition toward a belief in 

 the Christian doctrine of the Resurrection of Christ as a proof of that 

 which he cannot help but desire to believe. Contemporary Review. 







THE SOURCE OF LABOR. 



SCIENCE has taught us that the processes going on around us are 

 but changes, not annihilations and creations. With the eye of 

 knowledge, we see the candle slowly turning into invisible gases, nor 

 doubt for an instant that the matter of which the candle was composed 

 is still existing, ready to reappear in other forms. But this fact is 

 true not only of matter itself, but also of all the influences that work 

 on matter. We wind up the spring of a clock, and, for a whole week, 

 the labor thus stored up is slowly expended in keeping the clock going. 

 Or, again, we spend five minutes of hard labor in raising the hammer 

 of a pile-driver, which, in its fall, exerts all that accumulated labor in 

 a single instant. In these instances, we easily see that we store up 

 labor. Now, if we put a dozen sovereigns in a purse, and none of 

 them be lost, we can take a dozen sovereigns out again. So in labor, 

 if no labor be lost, as science asserts for the inertia of matter, its 

 very deadness, so to speak, which renders it incapable of spontaneously 

 producing work, also prevents its destroying work when involved in it 

 we should be able to obtain back without deduction all our invested 

 labor when we please. 



Imagine a mountain-stream turning an overshot wheel. It thug 

 falls from a higher to a lower level. A certain amount of labor would 

 be required to raise the water from the lower level to the higher; just 

 this amount of labor the water gives out in its fall, and invests, as it 

 were, in the wheel If, however, when arrived at the lower level, the 

 water were to demand of the wheel to be pumped up again, the 

 Highest trial would show that it would ask more than it could obtain,
