molivc power corrcspon-.lmg wllh the rcsis!ancc to be overcome, Is 

 imliqiensablc to s'art and keep it in operallon. 



So, in like mnnncr, (o put into operation the menial Aicuhics, and 

 keep up the arduous and elaborate invpstigalions necessary to pierce 

 the n:ysteries of nature, an.i pry out great inventions, adequate motive 

 must be superadded to ability. 



But again, according to the first law of nature, that of self-protec- 

 tion, and especially in this country, where each is cast upon his own 

 resources, and is the author of his own fortune, this motive or stimu- 

 lant, to prove eflectual in eliciting energetic action, must be of a char- 

 acter personal and beneficial to the party to be reached by its influ- 

 ence ; such as to promise the results of labor to the laborer, and ena- 

 ble him to anticipate with confidence the enjoyment of its fruits. 



This is a principle so well established by experience, as to have 

 become a settled fact in political economy, applicable, in general, to 

 all the busy scenes of life. 



But with what peculiar and unusual force does it apply to the en- 

 couragement ol inventron ? To arouse the inventive energies of a 

 nation and nerve the mind to the absorbing, emaciating mental scru- 

 tiny requisite to surmount the difficulties and discouragements en- 

 countered by the inventor, demands motive of the strongest and most 

 animating power. One which will call him from other pursuits, ap- 

 propriate his money in expensive experiments and his time to hard 

 study ; one which will cheer and animate him in solitary seclusion 

 from society and substantially from his own family ; one which will 

 sustain him amid disappointments and darkened prospects ; one 

 which will enable him to collect and recover his energies after the 

 prostration of his last hope, by an apparent failure in attaining his 

 long-sought result ; one which will induce self-denial of the ordinary 

 diversions of society, and year after year hold him steady to his pur- 

 pose, until the best of his life has been exhausted in devouring ab 

 straclion.
