20 YALE AGRICULTURAL LECTURES. 



such numbers that a small contribution of time and labor from 

 each shall make a sufficient aggregate to meet the object in 

 view." You will understand, then, that mainly to Professor 

 Porter, and not to Yale College, the honor of originating this 

 plan is due. Yale has done something for scientific agriculture 

 since about the year 1848, when a Professorship was partially 

 endowed for the late Prof. John Pitkin Norton, who had la 

 bored some time with Johnston in England. Norton died in 

 1852, much regretted, after having done as much as he could 

 to make his department useful and popular, and was immedi 

 ately succeeded by Prof. J. A. Porter, who was called from 

 Brown University. Porter's incumbency ksted five years, 

 when he accepted the Chair of Organic Chemistry, resigning 

 his own place to a rising young man, Samuel W. Johnson. 

 Mr. Johnson had studied two years in the Scientific School 

 here, and then went to Germany, where he worked in Leipsic 

 a year, in Erdmann's laboratory, and an equal time with the 

 great Liebig, at Munich, beside making visits to various labor 

 atories and schools in Germany, England, and elsewhere. 

 Since he took his Chair at Yale, he has held the office of Chem 

 ist to the State Agricultural Society, and made some notable 

 analyses of muck and phosphates, the latter of which have oc 

 casioned much controversy. 



He opened the course this morning with an elementary lec 

 ture on agriculture, confining his remarks to the organic ele 

 ments of the plant, and explaining their nature and properties 

 by the usual experiments. 



Three lectures are to be given daily (except Saturdays and 

 Mondays, when there will be but two,) until the 25th of this 

 month. The morning lecture is at 11 ; the afternoon, at 3, and 

 the evening one at 7 o'clock. 



The 3 o'clock lecture to-day was by Mr. DANIEL C. EATON. 

 an amateur botanist of this city, who has, I am told, a very ex 

 tensive herbarium, and has given many years of study to his 

 specialty. His lecture to-day treated of the vegetable cell
