		<head>Scope and Content Note</head> 
		<p>The papers of Alexander Dallas Bache (1806-1867) span the years
		  1828-1863 and include six series: 
		  <ref show="replace" actuate="onrequest" target="gencor">General
			 Correspondence</ref>, 
		  <ref show="replace" actuate="onrequest" target="speccor">Special
			 Correspondence</ref>, 
		  <ref show="replace" actuate="onrequest" target="jour">Journal</ref>, 
		  <ref show="replace" actuate="onrequest" target="scrap">Scrapbook</ref>,
		  
		  <ref show="replace" actuate="onrequest" target="misc">Miscellany</ref>,
		  and 
		  <ref show="replace" actuate="onrequest" target="add">Addition</ref>.
		  The bulk of the material is concentrated in the years 1836-1838 and 1857-1863.
		  </p> 
		<p>The 
		  <ref show="replace" actuate="onrequest" target="gencor">General
			 Correspondence</ref> series relates mainly to the United States Coast Survey
		  when Bache served as superintendent, 1843-1867. During his administration the
		  Coast Survey published detailed maps of the East Coast of the United States.
		  Its navigation charts of the Carolina and Georgia coasts were used during the
		  Civil War to assist in enforcing the blockade of Southern ports.</p> 
		<p> Bache devised new instruments and methods to improve the work of the
		  Coast Survey. While with the Survey, he also served on the Light-House Board
		  and was superintendent of weights and measures, coordinating these activities
		  to produce detailed navigation charts. Correspondents include John Jordan
		  Crittenden, John A. Dahlgren, Charles H. Davis, Benjamin A. Gould, Joseph
		  Henry, Benjamin Peirce, Benjamin Silliman (1816-1885), and George E.
		  Waring.</p> 
		<p> The Dudley Observatory in Albany, New York, was established in 1856
		  for the advancement of astronomy. Bache was a member of the Scientific Council
		  which directed the Observatory’s research and controlled daily operations;
		  other council members were Benjamin Gould, Joseph Henry, and Benjamin Peirce. A
		  conflict of interest between the Scientific Council and the Board of Trustees,
		  which almost destroyed the Observatory, is detailed in the 
		  <ref show="replace" actuate="onrequest" target="speccor">Special
			 Correspondence</ref> series. Principal correspondents were Blandina Dudley,
		  main financial supporter of the Observatory, and Benjamin Gould, Joseph Henry,
		  Thomas Olcott, Benjamin Peirce, and C. H. F. Peters. </p> 
		<p>A 
		  <ref show="replace" actuate="onrequest" target="scrap">scrapbook</ref>
		  of newspaper clippings reflects Bache's interest in scientific developments of
		  the period. The 
		  <ref show="replace" actuate="onrequest" target="misc">Miscellany</ref>
		  series consists of a partial index of correspondents between 1857 and 1860, and
		  the 
		  <ref show="replace" actuate="onrequest" target="add">Addition</ref>
		  contains photocopies of letters from George W. Dean to Bache, 1860-1861.</p>
