DREDGING OUTFIT SUPPLIED TO THE U. S. S. THETIS. 



We remained at the navy-yard until April 5, when we proceeded to 

 Hampton Eoads, under the following orders : 



U. S. Commission of Fish and Fisheries, 



Washington, D. C, April 2, 1887. 



Sir : It is proposed to supply the steamer Thetis, now under orders 

 for the Pacific Ocean and Bering Sea, with such apparatus as may be 

 most conveniently available for making investigations respecting the 

 fisheries of the northwest coast and the general natural history of the 

 country in accordance with the offer of Lieutenant Emory, commanding 

 that vessel. As her departure is imminent it will be impossible to get 

 up in time a special outfit; and you will, therefore, supply such portions 

 of the fishery equipment of the Albatross as can be spared for the pur- 

 pose, and make, without delay, a requisition to replace them. 



You will proceed with the Albatross to Chesapeake Bay, or wherever 

 the Thetis may happen to be at the time, and make a transfer of the ar- 

 ticles in question, together with such additional equipment as may be 

 put on board by Mr. Lee or Mr. Eathbun. 



If the necessary arrangements can be made, it is desirable that you 

 give Lieutenant Emory and the officers of the Thetis an opportunity of 

 witnessing the methods of making collections and observations on the 

 subject in question. On reaching the Thetis, therefore, you will invito 

 them to accompany you on a trip of such length as may be most con- 

 venient for all parties. 



I learn that the officers of the Thetis will not be ready for any trip 

 with you before Thursday next ; and you will therefore leave the navy- 

 yard, Washington, in time to meet the Thetis in Hampton Roads on 

 that day. 



Respectfully, 



Spencer F. Baird, 



Commissioner. 

 Lieut.-Commauder Z. L. Tanner, 



Commanding Steamer Albatross. 



We anchored off Fortress Monroe at 1.35 p. m., April G. The U. S. 

 S. Thetis arrived on the morning of the 8th, anchoring near this vessel, 

 and at 9.30 Lieutenant Emory with several of his officers came on board 

 for the purpose of witnessing the practical working of our dredging 

 apparatus, for which purpose we got under way and made several hauls 

 of the trawl, coming to anchor again at 11.30. The following articles 

 were transferred to the Thetis :
