LETTER TO THE SECRETARY OF WAR. 



tions taken upon the routes explored. Dr. Newberry was only attached to my command for a 

 few days, as he proceeded by water from Fort Dalles to San Francisco, where he remained until 

 the completion of the field work. While waiting in that city he zealously occupied himself in 

 making a large and valuable zoological collection. His reports speak for themselves. The great 

 energy which Mr. Coleman displayed in discharging the laborious duties of chief of train, is worthy 

 of the highest praise. Had it not been for his continued and untiring exertions, many of our 

 animals must have been lost in crossing the Cascade mountains. To the men of the topographical 

 party generally, much commendation is due. Although deprived of the protection of an escort, 

 and of the services of a physician, to both of which they were entitled by the terms of their agree 

 ment, they, with hardly an exception, faithfully performed their duties until the end of the survey. 



I am, sir, very respectfully, your obedient servant, 



HENRY L. ABBOT, 

 2d Lieut. U. S. Topographical Engineers. 



Hon. JOHN B. FLOYD, 



Secretary of War.
