pose to promote the wealth, the health, and the happiness of each other, and the honor 

 of our DQUch-loved country. 



In taking the first step toward the erection of this house, to be dedicated to the 

 work of agricultural science, we address ourselves to the merchant and mechanic, the 

 active and energetic motive-powers of busy life, and ask them to look with favor upon 

 a project which has for its object the display of industry and science, as exemplified 

 by the products and implements of agriculture. The busy marts of men are filled with 

 the pro'ducts of the farmer. His success and his profits largely contribute to that trade 

 and commerce which are the products of your enterprise. 



While the abundant yield of the husbandman enriches him, the result is favorably 

 felt in every department of the merchant's counting-house and the mechanic's shop. 

 As then you move and make your impress upon the minds of men, let your actions be 

 tempered with the idea that all business, whether in the merchant's store, the me- 

 chanic's shop, or the mariner's ship upon the ocean, is dependent for its working ele- 

 ments upon the product of the farm. 



We will not appeal in vain to the professor and the student, who possess the lights 

 of reason and enjoy the fruits of knowledge, that their influence may be thrown into 

 the scale of agricultural progress, that while you have in your hands that helm of 

 power which gives direction to the elements of government j'ou will always have in 

 mind that to promote the true and efficient principles of political economy, to expand 

 and increase the influence of that virtue whereby alone we may hope to maintain our 

 own free government and laws, is to encourage the farmer. 



We ask cf the statesman while he advocates the interests of his constituents at the 

 bar of the Senate, of the lawyer who advocates the cause of his client at the bar of 

 justice, and of that sacred oflice which advocates the cause of man at the bar of 

 Heaven, that they may ever remember the magnitude of the bounties of God's provi- 

 dence which come from the hands of the husbandmen. 



Let me not forget to exhort her whose influence is always so strongly marked upon 

 the characters of men, from their cradle to their grave, to look kindly and with favor 

 upon that marked morality which characterizes the life of the husbandman — the 

 mother whose aflections root so deeply in the existence of her child ; whose anticipa- 

 tions are often stimulated to painful anxiety ^r its welfare ; who watches its progress 

 in life with an eye to doubt and danger ; whose hopes are elevated to the Giver of all 

 good, that He may smile graciously iipon the career of her darling child, or whose 

 fearful forebodings may be realized in the spectacle that he is despised by the society 

 of men and frowned upon by the attributes of Heaven. We invoke the prayer of this 

 influence on the work this day began. And to all those assembled here we ask a help- 

 ing hand and cheerful spirit in aid of those patriotic men who have undertaken to ex- 

 hibit to the world the progress which has been made in science and ai"t under the 

 stimulating influence of a free government. 



EiNTOMOLOGICAL RECORD. 



By Townend GloveBj Entomologist. 



The chinch-bug. — The chinch-bug or Mormon louse of Walsh, Mi- 

 cropus {BliyparocJiromus) devastator, is one of our most destructive 

 insects to wheat, corn, &c., in some of the Western States, and 

 has done considerable damage to the crops. The eggs, to the 

 number of about 500, are laid in the ground about June, on or 

 among the roots of plants, and the young larvae, which are of 

 a bright-red color, are said to remain underground some time 

 after they are hatched, sucking the sap from the roots, and have 

 been found in great abundance at the depth of an inch or more 

 The full-grown insects measure about one-twelfth of an inch in length, 

 and are of a black color, with white wings, and may be known by the 

 white fore or upper wings, contrasting with a black spot in the middle 

 of the edge of the wing. • 



According to Dr. Shimer, an entomologist who has devoted much time 

 and labor in the special study of this insect, the female occupies about 

 twenty days in laying her eggs, which remain in the egg state fifteen 

 days. The first brood matures from mid-July to mid- August, and the
