good work of collecting definite information, and as action on our part 
might be regarded as interfering with those, he, (Dr. K.,) moved that the 
committee be discharged ; which was so ordered. 
Dr. A. L. Elwyn feared that the State Society would not succeed this 
year in obtaining the publication of its proceedings by legislative enact- 
ment. 
H. Ingersoll proposed to amend 19th by-laws, so as to render the Presi- 
dent eligible for more than two terms. 
Dr. Kennedy moved, that the Executive Committee be requested to 
report at next meeting on the expediency of the Society's holding an exhi- 
bition next autumn. 
Voted, on motion of Dr. Kennedy, that delegates be now elected to 
represent this society at the next session of the United States Agricultural 
Society, to be held at Washington, on the 28th inst. 
Voted, on motion of A. S. Roberts, that the delegation be appointed by 
the chair, and that they have power to fill vacancies ; whereupon the follow- 
ing gentlemen were appointed: A. L. Kennedy, A. T. Newbold, A. S. 
Roberts, H. Ingersoll, J. McGowan, C. W. Sharpless, A. Clement, S. Wil- 
liams, J. S. Haines, S. C. Willits, Gr. Blight, C. W. Harrison, Gen. R. 
Patterson, J. Pearson, and S. C. Ford. 
Dr. Elwyn laid before the society, samples of dust from the flues at the 
foundry of Mr. Charles S. Smith. This dust collected in large quanties, 
both from the bituminous and anthracite coal fires. It had been spread on 
land, and was believed to produce about one-half the fertilizing effect of 
guano. Further experiments were necessary before its exact value could 
be determined. These he hoped members of the Society would make. 
For such a purpose they would cheerfully be furnished with a supply on 
applying at Mr. Smith's Iron Works. The researches of chemists and the 
introduction of guano, had done much towards directing the attention of 
farmers and others to concentrated manures, and the employment of waste 
products. The samples before the society were evidences in point. Further 
investigation would reveal many substances now mere refuse, which either 
alone or in mixture, would prove rich boons to the agriculturist. Dr. 
Elwyn had learned that during last season, guano had not proved signally 
beneficial to the lands of Chester county on which it had been used. When 
mixed with lime the effect had been much more manifest. 
Mr. A. M. Spangler had had occasion to observe the comparative yield of 
land manured with guano and superphosphate of lime, and in nearly all 
cases had the latter proved more advantageous, and this not only on wheat
