670 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



While too high an estimate cannot well be placed upon the beneficial 

 results of the air-pump, I cannot close without reiterating my former 

 expressions in favor of the two principal accessories to the successful 

 transportation of carp, namely, fresh water and ice. 



As it is impossible for one man to fill up and handle the barrels dur- 

 ing the voyage, the assistance of the captain and crew is often necessary, 

 and in this connection I cannot speak too highly of Captain Froboes, 

 the first officer of the Lessing, who manifested great interest in the 

 enterprise and rendered invaluable assistance. I have also to thank my 

 zealous assistant, Mr. Ernst Eehre. 

 Very respectfully, 



Dr. OTTO FINSCH. 



Washington, D. C, May 16, 1S79.
