formindskede Riggen og foretog Forandringer ved Aptefin- 

 gen, saaledes at der blev Plads for de til Expeditionen 

 horende Videnskabsmænd og deres Arbejder, foruden til 

 Officierer og Mandskab samt stort Ruin til Kul, vikle man 

 faa et Fartøj. som i saådant Vejr. som udfordres til de 

 videnskabelige Arbejder, kunde manøvreres fuldstæncligt for 

 Maskinen, og i mere uroligt Vejr kunde manøvreres som 

 Sejlskib, hvorved Betingelserne altsaa vare givne for den 

 storst. mulige Kulbesparelse og Kulbeholdningens Forslag 

 for en længere Tid. noget som var nødvendigt for Expedi- 

 tionens Arbejder ude paa det aabne Hav langt fra Kulde- 

 pot. Omkostningerne ved en saadan Forandring er af Ny- 

 lands Verksted beregnet til 17,000 Spd. Sku kle tillige ny 

 Maskine udfordres. hvad der neppe er nødvendigt. ville 

 [Jdgifterne stige til henimod 25,000 Spd. 



C. Man kunde leje et Dampskib for den Tid, der 

 var nødvendig for Expeditionen hver Sommer, saa længe 

 den vårede. Omkostningerne herved er det ikke muligt at 

 opgive, da disse dels ville bero paa Conjuncturerne. dels 

 være afliængige af de Indredninger, som Fartøjet nødvendig 

 maatte gives, for at være skikket til Expeditionsfartøj. 



Af disse tre Alternativer er det forste det mest anbe- 

 falelsesverdige, da det vikle give den største Fribed med 

 Hensyn til det hele Arrangement. I denne Henseende er 

 man noget bundet ved Alternativ B, og i højeste Grad ved 

 Alternativ C. Ved dette sidste havde man endog den ube- 

 hagelige Risico. at maatte foretage nye Foranstaltninger 

 for hver Gang, Expeditionen skulde udrustes, og kunde 

 aldrig gjøre Regning paa hver Gang at faa beholde det 

 samme Skib. 



Næst Skibet udfordres der til Expeditioaens Øjemed 

 en hel Del Apparater, som Dybvandsliner til forskjelligt 

 Brug (Temperatur, Skrabninger, Strømundersøgelser) Lod- 

 der. Patentblokke, Accumulatorer, Thermometre. Skraber, 

 Xet. fysiske (magnetiske) Apparater, Glas, Spiritus m. m. 

 Efter velvillig Opgave af Gapt. Da vis af det Britiske Ad- 

 miralitets hydrografiske Afdeling vil man kunne udruste et 

 mindre Skib med de for Dybvandsundersøgelser nødvendige 

 Apparater tor en Sum af 1.000 til 1,200 Lstrl. eller 4,500 

 til 5,4on Spd. 



Omkostningerne ved at holde Expeditionen ude. nem- 

 lig Hyre, Kost. Kul. Vedligeholdelse m. m. ere af Capitain- 

 lieutenani *'. Petersen, der velvillig har bistaaet os ved 

 Udarbeidelsen af tiisse Overslag, beregnede til 2000 Spd. 

 pr. Maaned. Dette giver for en Tid af 2 1 / 2 Maaned en 

 Sum af ."ii mk i Spd. aarlig. 



Hvormange Sommere, der ville medgaa, førend Ex- 

 peditionens hele Øjemed var naaet, er det ikke muligt paa 

 Forhaand at sige. Det kommer her saa meget an paa 



hvilke Forhold man ved Undersøgelserne linder og hvorle- 

 des Yojret arter si^. Vi tro dog. at man i 2 meget gun- 



boilers. less heavily sparred, and fitted up below deck in 

 such manner as to afford room alike for the personal ac- 

 comodation of the members of the Expedition. and for such 

 part of their work as could be done on board. as also for 

 the officers and crew. together with stowage for coal. the 

 "Alfen" would be a vessel which, in weather admitting of 

 the scientific exploration of the ocean, might be worked 

 as a steamer, and. in a heavier sea, as a sailing-ship, thus 

 securing the conditions requisite for the greatest possible 

 economy in the consumption of fuel, and for adjusting the 

 stock of coal to the leiigth of the period during which the 

 Expedition would have to cruise in the open sea, far from 

 any coaling-station. The cost of such alterations has been 

 estimated by the Manager of the Nyland Works at Spd. 

 17.000. New engines — which however will hardly be 

 wanted — would raise the outlay to about Spd. 25.000. 



C. A steamer might be chartered every summer for 

 the period over which the cruise of the Expedition would 

 extend. iVs regards the cost, nothing definite can be stated, 

 since the amount must depend partly on the state of the 

 freight-market, and partly on the expense entailed by adapt- 

 ing the vessel to the requirements of the Expedition. 



Of these three alternatives, the first is. in our judg- 

 ment. the most desirable, admitting as it does of greater 

 freedom in the general arrangement. The character of the 

 second alternative. B. would. to sonie extent, be found 

 restrictive in its operation; but the third alternative. ('. 

 might. if selected. lead to serious inconvenience and uncer- 

 tainty. involving as it would the risk of new arrangements 

 having to be made for each successive cruise, since the 

 Expedition could hardly rely on being able to retain during 

 the whole period of its duration the vessel originally chosen. 



Next in importance to the sbip. are the apparatus 

 and appliances of various kinds with which the Expedition 

 would have to be furnished. such as deep-sea lines for 

 divers purposes (temperature. dredging. investigation of 

 currents), sounding-leads. patent blocks. accumulators. 

 thermometers. dredges. nets, physical (magnetical) instru- 

 ments, glass jars. tubes. &c. and spirits of wine. &c, &c. 

 According to a statement kindly fuVnished by Captain 

 Davis of the Hydrographic I (epartment of the British 

 Admiralty, a vessel of moderate size might be fitted out 

 with the instruments and apparatus necessary for such 

 an Expedition at a cost of from 1000?. to 1200/. (Spd. 

 4500—5400). 



As regards the current expenses of the Expedition. 

 viz. for seamen's wages. rations, coal. wear and tear of 

 vessel, &c. &c, these are put by Commander C. Petersen, 

 R. N., who has kindly assisted in furnishing the above 

 estimates, at Spd. 2000 a month. Hence. according to 

 tliis calculation. the cost of a 2',.. months' cruise would be 

 Spd. 5000.- 



How nia ny summers would elapse ere the object of 

 the Expedition had been fully attained. it is of course im- 

 possible to state beforehahd, so mach must necessarily 

 depend on the proportions the investigation would .issume, 

 and on the weather. Meiinwhile. your memorialists are of
