pices of government in Much of the 



work is dedicated to inquiries respecting 

 the aboriginal population, but much valua- 

 ble geological information is also contained 

 in the volume. The district of the lead 

 mines was again examined, and his former 

 observations, which had been misconceived 

 and controverted bj some geologists, were 

 now fully confirmed and verified. 



We have been thus minute in pointing 

 out the several routes of these various ex- 

 peditions, that we may be enabled at a 

 glance to ascertain what particular districts 

 have been examined with a view to their 

 natural products. It will also enable our 

 naturalists more readily to select for future 

 examination, such portions of the country as 

 have not yet been fully explored. 



While we thus gratefully state our obli- 

 gations to the government, for the services 

 they have rendered to the cause of science, 

 let us hope that the same enlightened po- 

 licy which has given this direction to a por- 

 tion of the energies of the nation, may con- 

 tinue to operate. Let us hope that the pre- 

 sent administration may be authorized to 

 execute the various plans it has proposed ^
