32 The American Geologist. January, i8Q4 
fruit, and shedding leaves of all trees and shrubs in the localities he 
happened to be in. 
1834. List of American shells. Was evidently prepared for exchang- 
ing specimens, possibly with an idea of publishing sometime. There is 
a great deal of work in it, done with and for judge Benjamin Tappan 
and Dr. S. P. Hildreth, with a criticism of Conrad's table of American 
Naiades, suggesting many alterations. I do not know w T hether they 
met with favor. 
1836. Change of level of lake Erie, and Else and fall of lake Michi- 
gan. I still cannot satisfy myself in regard to these two papers. They 
evidently were ready for publication, and may have been in some news- 
paper, as he frequently wrote for the Sentinel. There was however, no 
paper in Milwaukee at that time. 
1840. A week in Wisconsin. Its animals, plants and mounds. 
This was probably published in the Sentinel, but there is nothing to 
show it. On nearly all his trips through the state and elsewhere, he 
wrote letters to the Milwaukee papers. One series was headed "Glances 
at the Interior.'" 
1849. Geological Notes : Tour to the Dells. May have been published 
as above. 
1851. Geology of Wisconsin. We have the manuscript. 
[There is a paper by Dr. Lapham on the "Geological formation of Wisconsin,"' in 
Trans. Wis. State ArI. Soc, Vol. 1, 1851, written about this date, but as Miss Lapham 
states that this unpublished article is illustrated, it is doubtful whether they are the 
same. One figure is designed to show the Wisconsin geological column, beginning 
with the "Primitive" and ending with the Devonian, the last surmounted by the drift, 
lake deposits and the soil. The thickness of each formation is expressed in feet, the 
sedimentary rocks and drift amounting to 1950 feet. Another figure, supposed to be- 
long to this unpublished article, is "a section showing the equivalence of the Mar- 
quette and Menominee iron deposits, by Prof. Raphael Pumpelly,'' but it is appar- 
ently misdated and out of place. N. H. W.] 
1836-71. Meteorological manuscript. Some of this has been pub- 
lished, but a great deal of it has not. 
1853. American Paleontology. There is a great deal of work done 
here, and I send you the agreement between father and Prof. Hall. Why 
it was not carried out I do not know. Evidently father did his part of 
the work. 
[The agreement referred to by Miss Lapham is as follows, in Lapham's hand : 
This agreement, made this first day of March, A. D. 1853, by and between James Hall 
of Albany, A. [N.] York, and I. A. Lapham, of Milwaukee, Wisconsin, witnesseth: 
That said Hall agrees to prepare a work to be called American paleontology, et cetera, 
based upon manuscripts now placed in his hands by said Lapham (which manuscript 
embraces descriptions of about two thousand species) and to procure the publication 
thereof upon the most favorable terms, as the joint work of said Hall and Lapham ; 
that in case no publisher is found to assume the expense of the publication, then the 
work is to be published at the joint and equal expense of the said parties hereunto ; 
that said work and publication is to be completed within one year from the date 
hereof, and that all proceeds and profits resulting from the said publication are to be 
divided equally between the parties aforesaid. 
Witness our hands, our hands on the day and year first above written. 
In presence of / JAMES HALL,
