skere. Herom have vi allerede modtaget Vidhesbyrd fra 

 disse Kanter., Paa samme Tid have vi og bragt i Erfa- 

 ring, at den Britiske Regjering ikke agter at lade „Chal- 

 lenger" overtage demie Undersøgelse af yort Ishavsbækken, 

 som vi her have for Øie. 



Til Udførelse af Expeditionens Arbejder kræves ep 

 Zoolog med et Par Assistenter, en Fysiker og en Ohemi- 

 ker, forsaavidt det Videnskabelige angaar. Til Arbejdstid 

 maatte vælges de roligste Sommermaaneder, tlii med uroligt 

 Hav er Arbejdet i de fleste Retninger umuligt. 2 1 9 Maa- 

 ned. fra Midten af -Juni til* Slutningen af August er den 

 længste Arbejdstid, man kunde gjøre Regning- paa. og af 

 denne Tid vikle mange Dage ikke kunne benyttes, naar 

 Vejret er uroligt. 



Af de til Expeditionen fornødne Apparater er Skibet 

 det vigtigste og kostbareste. Et saadant maatte være et 

 Dampskib, der besad tilstrækkelig' Kraft til at manøvreres 

 for Maskinen i ethvert saadant Vejr, hvori Uhdersøgelser 

 af .Havdybet overhovedet kunde foretages; det maatte kunne 

 medtage Kul for en længere Tid og have en brændebespa- 

 rende Maskine, have flere Baade til forskjellige Undersø- 

 gelser og et tilstrækkeligt Mandskab til Udførelse af alle 

 med Dybvandsundersøgelser forbundne, ikke ganske lette 

 Arbejder. .Til disse udfordres ogsaa et Dampspil. Des- 

 uden udfordres et Arbejdsrum for de videnskabelige Under- 

 søkelser, som kunne udføres ombord. 



Efter de Undersøgelser, vi ved Sagkyndiges Hjelp 

 have anstillet. tindes der blaudt norske Dampfartøjer for 

 Tiden ikke noget, som opfylder de nævnte Betingelser. 

 Med Hensyn til Tilvejbringelse af et passende Fartøj for 

 Expeditionen stiller der sig nu trende Alternativer. 



A. Anskaffelsen af et nyt Skib. Med Hensyn til 

 dette Punkt ere vi saa heldige at kunne nævne et Over- 

 slag over dets Kostende, som er blevet os velvillig meddelt 

 af Nylands mekaniske Verksted. Dette Verksted har nem- 

 lig fra den russiske Regjering, modtaget Opfordring til at 

 udarbejde Overslag over Omkostningerne ved Anskaffelse 

 af et nyt Jemdampskib, med Skrue, skikket til Opsyns-og 

 Opmaalingsfartøj, af en Størrelse og med en Udrustning 

 og Indredning, som paa det allernærmeste falder sammen 

 med, hvad vi efter Samraad med Sagkyndige anse passende 

 for en Expedition som den af os her omhandlede. Et saa- 

 dant Skib vilde efter Nylands Verksteds Overslag, med 

 fald Udrustning, Dampspil. Baade. Høj- og Lavtryks-Ma- 

 skine af fuld Kraft for Fartøjet, koste 40,000 til 45,000 

 Spd. efter Nutidens Priser. 



B. Den Krigsmannen tilhørende Skrueskonnert "Al- 

 len", som man jhavde tænkt at sælge, kunde med en pas- 

 sende Omforandring blive et for Expeditionen hensigtsmæs- 

 sigt Skil). Naar man forsynede Fartøjet ined ny bensigts- 

 massigere og større Skrue, en ny større og sterkere Kjedel. 



øu the pari of British savcmts. Of this we liave alreadj 

 received assurance. We are also able to state, that the 

 basin of the Arctic Ocean will not be investigated b'v the 

 •■< Jhallenger" Expedition. 



The scientific work invdlved in such an undertaking, 

 would call for the services of a naturalist, with øne or two 

 assistants, a physicist, and a chemist. As regards the most 

 titting season of the year for the cruises of the Expedition, 

 this would be oliviouslv the finest summer months; for in 

 rough weather the greater part of the work of which there can 

 be question is utterly impracticable. Two months and a 

 half -- from the middle of .lune to the end of August - 

 might be reasonably calculated upon, including of course 

 nianv*stoiniv days on which nothing couhl be done. 



Of all that is needed for the Expedition, the choice 

 of a vessel would be the chief consideration, as her acqui- 

 sition would involve the greatest outlay. She should be a 

 steamer. with an engine sufficiently powerful to admit of 

 working lier in any weather that did not render the ex- 

 ploration of the ocean-depths altogetber impracticable: 

 sbe must. too, be able to take out coals for a considerable 

 period, have an engine specially adapted for economising 

 fuel, be provided with several boats, in which, when occa- 

 sion called. to put off from the ship, and moreover be 

 manned by a crew -sufficiently numerous* tn do all the 

 work connected with sounding, dredging, trawling, &c, 

 which. beihg niostly of a laborious chaxacter, would require 

 a steam-winch for its effective execution. Finally, there 

 must be room on board for instituting such observations 

 and experiments as admit of being undertaken at sea. 



Having made inquiry of persons specially conversant 

 with the subject. we are in a position to state, that. at the 

 present moment, there is no Norwegian steamer that fultils 

 ■ the conditions specitied above. Now. as regards the acquisi- 

 tion of a vessel for the proposed Expedition. choice can 

 be made between tbree alternatives. 



A. The purcbase of a new vessel. With respect to 

 this alternative, we are in possession of an estimate. kindly 

 furnished by the Manager of the Nyland Mechanical Works. 

 The said Works have been requested by the Russian Gov- 

 ernment to give an estimate of the cost of an iron screw- 

 steamer tor the Coast Survey of that country, which. as 

 regards burden, tackling. and general equipment corresponds 

 very nearly with the description of vessel that we. having 

 duly consulted experts, bebeve to be most suitable for the 

 Expedition proposed in this Memorial. Such a steamship, 

 fully equipped, with compound engines. steamwinch, boats. 

 &C, could, as prices now stand, accordmg.to the estimate 

 of the Nyland Works, be built for a sum of from Spd. 

 40,000 to Spd. 45,000. 



B. The screw-scbooner •■Alten." belonging to the 

 Royal Navy. which was to have been sold. might, by suf- 

 ficiently extensive alterations, be made a suitable ship for 

 the Expedition. Furnished with a new and improved pro- 

 peller of increased dimensjons, with larger and stronger
