by the enterprising, and successful, and intelligent laborers 

 in this vineyard which we have inherited. For the part 

 which this institution has performed in the encouragement 

 of scientific research, as one element of our busy civiliza- 

 tion, this country ought always to l)e grateful. I value 

 all the accomplishments of our people, their ingenuity 

 and skill, their vigorous literature, their advancement in 

 the business of common school education, their devotion 

 to the cause of freedom, their material success, their intel- 

 lectual accomplishment, their moral elevation which calls 

 for honesty, and frowns on dishonesty, in public affairs. 

 But I think I am more gralitied with the l)ond they have 

 created between themselves and other nationalities, by 

 their progress in practical science, than by any other of 

 their achievements. I am reminded here, that it was not 

 the skill of the diplomatist which opened to the inquiring 

 young American the great triumph of European engi- 

 neering, but the reputation secured by a son of this 

 town, a friend of this institution, Benjamin Peirce, the 

 great explorer in the profoundest fields of mathematics. 

 For this recognition, I am profotmdly grateful; and I 

 congratulate the young men who are giving their energies 

 to the scientific association of the Essex Institute, on the 

 position secured for them in these modern days, by the 

 great leaders whom they follow through the field upon 

 which they have entered. 



I congratulate this city on the existence of the Institute, 

 and I congratulate the founder of the Institute that his 

 eyes behold this cheering and joyful anniversary. 



Nathaniel Paixe, Esq., President of the Worcester 

 Natural History Society, returned thanks to the Essex 

 Institute for its example, which had been a great benefit 

 to the Worcester society, and tendered his. warm con- 

 gratulations on the attainment of this anniversary.
