State of New Yorlc. The main geographical fea tures or every country, as well a:.; its oils anfl vegetable productious, depend npon the na ture of its geological fo rmations~ So universally true is this, that a suite of tile rocks prevailing in auy couutry, with their mineral and fossil coutents, wilt convey tnore absolute infonuation regarding the agricu ltural u.ud other capabilitie of that country than could be given by a voltllne written willwnt reference to the e sub~ jects. Jnueed, no survey or au y unknown regiou should Lw made withou at the same time preserving eollcctions of the prevailitw rocJ s, minerals and fossils. 'r'he attentioll g iven to this subject iu tllC foregoiug report renders the information of the highust value, and perf(:ctl y rei table in reference to opinious or calculations rcgard itt 1" the resources of the conn try. The specimens examined prcseut a great variety of aspect a11d composition; but calcareous rocks prevail over a large porti(Jn of the conutry traversed between lougituJe 98° aucl the uwntlt of lhc Col 111ul>i:t river, or 122° west from Greenwich. That portioll of the ronte cmhract'U in tltis notice varies in latitude through sevcu degrees, vi2: ::3 ° to 45° uortll; and speci~ cns arc pre euted in uearly every half d e~ rec of latitude. . ,nch a collecllon enable · u to form a very sati~factory concln:-;ion regardiu cr tbi. portior1 of the coulltry, 7° in width and 24° iu length; having an extent east and west equal to the distance between the Atlantic coast of New York and the Mis issippi river, and l.yin O' iu the temperate latitu de~, which extend from Washingtou city to the uorthcrn limit of the State of New York. Although we arc far from beiuo· able to fix tlw minute or detailed geology, this collection prcscuts us wi~t suffici ent 1natcrial. to form son1e probable conclusions regarding tltc whole region f'rolll this side of the Rocky mountains westward to the mouth of tb~e Columbia river. Bnt it is not within n.lY province to dwell upon the advantao·e opened to us in the vast field whJr.h the researches of Captain Fremont have made lnown. I therefore proceed to a description of the specimens os tltey occl:lr, taking thern In the Ot'dcr from cast to west.
