the lineal surveys of lands of tlie United States, tlie first experi- 

 mental results of which are now returned to this department." 



It may be proper to add parenthetically that the system of geolog- 

 ico-linear surveys was continued during the season of 184G. We find 

 a report by William A. Burt, announcing the discovery of masses of 

 iron ore in the Menominee district; a report by Bela Hubbard as 

 deputy survej-or and geologist with S. W. Higgins as chief assistant; 

 also a report bj' Bela Hubbard as deputy surveyor, with William 

 Irons as assistant. These reports, 1844, 1845, and 1846. are accom- 

 panied by well engraved maps of the territory covered and work 

 done, together with interesting views and sections illustrative of 

 geology and scenery. The records of these surveys are contained in 

 Annual Message and Documents 1840-50, part 3, pages 802-935; 

 but were not published before 1850. On March 1, 1847, an act of 

 Congress was approved, establishing " a land office in the northern 

 part of Michigan," and Dr. Charles T. Jackson was appointed by 

 Secretary of the Treasury Robert J. Walker to make a geological 

 report. His report is dated Boston, November 10, 1849, and is con- 

 tained in the same published volume as those of Burt and Hubbard, 

 above cited.
