.... On our arrival at Suva we found the ' Yaralla,' a 

 twin-screw steamer of about 500 tons, chartered from the 

 Australasian United Steam Navigation Company, awaiting us. 

 We have now been about six weeks cruising among the islands, 

 and have found the boat admirably suited for our purpose. 

 During the past summer I had shipped to Australia our outfit 

 for dredging, sounding, and for deep-sea towing, as well as all 

 the materials necessary for preserving our collections. This 

 equipment we found safely stored in the ' Yaralla.' I had 

 also brought with me deej;-sea tow-nets of the various patterns 

 used by the Prince of Monaco, by Dr. Giesbrecht of the 

 Naples Zoological Station, and by Hensen on the ' National ' 

 Expedition, in order to compare their efficiency with the 

 Tanner deep-sea self-closing net in use on the ' Albatross ' and 

 which 1 had adopted on my various expeditions. Unfortu- 

 nately our time here is so limited and the conditions for towing 

 at great depths among so many intercepting islands are such 

 that the results likely to be obtained seemed to make it unad- 

 visable to devote the time necessary for such a comparison. 

 Although nothing was done to test the different deep-sea self- 

 closing towing-nets, yet we have made at various points along
