No. 140. Sulphate of barytes, with carbonate of zinc, sulphuret of zinc, and sulphuret of lead, from Mineral Point diggings.

Note.-Of the fossils collected, many are probably yet undescribed ; but until the receipt of several recent works of reference on organic remains, I am unable to determine this point.

reek, the last of thee. The generalstrations, lists


February 9, 1840. Dear Sir: Last week, the last of the township maps containing our annotations were forwarded to your office. The general report will not be completed for several weeks; the maps, diagrams, illustrations, lists, and analyses of ores and minerals intended to be imbodied and to accompany it, requiring much time and consideration.

By this post I send you the appendix, containing notes giving a description of the individual townships, and embracing details intended chiefly for reference; at the end will be found two tables, showing the proportion of prairie and timber in the Dubuque and Mineral Point districts, and a descriptive catalogue of the different varieties of specimens to be forwarded to Washington as soon as those collected in Wiskonsin arrive. Since we finished our operations at Stephenson, the winter has been so severe, and the snow so continually on the ground, that it has been impossible to make the examination of the townships in Illinois, in the neighborhood of Shaw. neetown. By the time my report is completed, I shall be prepared with a corps of from six to eight, to proceed with the examination, unless I receive, in the mean time, instructions from you to the contrary.

No communications have been received from you since my last letter. I am, very respectfully, your obedient servant,


Principal Agent, f'e. Hon. JAMES WHITCOMB.

P. S.-I find it necessary to retain the catalogue until the analysis of several ores and minerals, which I am now making, is completed, and draw. ings are made, to which it will be frequently necessary to refer.


Containing a particular description of each township.

Note.—The numbers designating specimens refer to correspordicg numbers on the labels of the different specimens forwarded to the department, to form a nucleus for a national cabinet. A descriptive catalogue of these specimens, with the numbers prefixed, is annexed to this appendix.

For the particulars of occupancy and claims,. the department is reterred to the annotations on the township maps herewith forwarded.

All the diggings of importance, and all the new discoveries of lead ore, are indicated on the general map, and on the township maps, by dots of vermilion, and (No. 34) the number of “ sulphuret of lead” in the caialogue and national cabinet; dots of green and (No. 110) represent, in like manner, the copper diggings and discoveries of copper; dots of yellow achre and (No. 15) indicate hydrated brown oxide of iron; dots of yellow gar boge and (No. 123) indicate localities of carbonate of zinc and calamite..
