REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



[2J 



Some repairs and alterations made it necessary to send the steamer 

 back to the ship-yard of the builders; and in April, 1883, the vessel 

 made her first cruise on the business of the Commission. 



Lieut, (now Lieutenant-Commander) Z. L. Tanner was ordered by the 

 Navy Department to superintend the construction of the vessel. He 

 made many important suggestions, and his practical experience was of 

 the utmost benefit in the final determination of the plan of construc- 

 tion. The equipment of the vessel was entirely under his direction, and 

 to his ingenuity is due a large number of the novel and important de- 

 vices and improvements adopted.
