culiar conditions for most favorable growth of different genera and 

 species suggests to the ingenious husbandman various methods of 

 obtaining the most desirable results in cultivation. 



Entomology teaches the nature and habits of insects, and 

 although their name is legion, and we may not be able to control 

 their depred?/.iuns so much as we could desire ; still we can do 

 much by knowing their habits, and their metamorphoses in re- 

 production. 



I need not say that a knowledge of comparative anatomy and 

 veterinary surgery is highly useful to the farmer ; for it is too 

 obvious to require argument. Many valuable animals would be 

 saved, if the farmer reflected that they, like men, have bodies 

 subject to disorders which rest and timely aid would cure. Cer- 

 tainly, we owe much gratitude to the animals which furnish us 

 with food and clothing, and add so largely to our comfort and 

 happiness in various ways; and though we may be willing to^ 

 submit ourselves to the practice of quacks, let us spare our ser- 

 vants of the brute creation. 



In addressing men familiar with mechanics, I need not dwell 

 upon the importance of the cultivation of the science of Mechan- 

 ical Philosophy and of Mechanics ; for the history of all the arts 

 shows how deeply they are indebted to these societies. It is said 

 by one of our most eminent agriculturists, that all the improve- 

 ments in the plough were made by mechanics and mathemati- 

 cians. Our power looms, spinning jinneys, self-acting muks, 

 cotton gins, carpet looms, printing presses, and thousands of other 

 ingenious machines, resulted from the application of the science 

 of mechanical philosophy. Steam engines, the combined result 

 of chemistry and mechanics, demonstrate the power of those two 

 sciences, when joined hand in hand. 



The sailing ship, which for ages has been an object of just 

 admiration, as she ploughs the deep, and works up against the 

 opposing wind, is a splendid result of science reduced to prac- 

 tice ; but now she stands still to admire that marvel of the waters, 

 the steam ship, as she marches through opposing currents and
