De nedentil paasatte Jernblade / støder mod Bunden og 

 hindrer, at Kranen bliver fyldt med Mudder. Til vort 

 Brun anbragtes istedetfor disse en last Jernstang med Øje- 

 bolt i den nedre Ende. i hvilken R,ør-Loddet indhexedes. 

 Apparatet rammede 2 Liter Vand. 



Under de for antydede ( >msta'iidigheder- er Apparatet 

 særdeles hensigtsmæssigt og Tætningen. paalidelig, men kom- 

 mer noget i Vejen under Nedfiringen, maa hele Operatio- 

 nen gjores om igjen, og dertil kummer, at Bremmen tillige- 

 med øverste Lukningsskive frembyder en ikke uvæsentlig 

 Modstandsflade under en hengere Indhivning. 



Forberedelser til Lodning. Lodlinen, 3000 Favne lang, 

 var oprullet paa den agterud om Bagbord i Dækket fast- 

 skruede Dækrulle, der sees i Fig. 1. 2 og 14. I Fig. 13 

 er denne vist tydeligere. Rullens Bom var 0. m 627 (2Fod) 

 lang. <'."1.")7 (ii Tom.) tyk og af Træ. 

 De cirkélformede Sideflader var af 

 tykke, galvaniserede Jernplader. paa 

 den indre Side plane, paa Ydersiderne 

 forstærkede ved dobbelte Lag af Jern- 

 plader. Deres Diameter var l.*"098 

 (3 Fod 6 Tom.) og deres Kanter var 

 afrundede. saa at de frembød en glat, 

 ringformig Made af omtrent 2.""(> (en 

 Tommes) Diameter. Paa Bagbord Side 

 var anbragt en Svejv afu.'"31 (1 Fods) 

 Længde med Træhaandtag. Stativets 

 tvende Dele var nedentil forbundne 

 med Jernstænger. og det hele hvilede 

 paa et Par langskibs løbende Bjælkei*. 

 gjennem hvilke Stativet var skruet fast 

 til Dækket.

Tampen af Lodlinen toges fra Rullen og manedes 

 gjennem Fodblokken paa Agterkant af Hytten (Fig. 14.) 

 Denne Blok var lidt mindre end Loddeblokken. og Skiven 

 solid, men forøvrigt af samme Konstruktion som denne. 

 Derfra manedes Lodlinetampen videre gjennem Loddeblok- 

 ken. der hang under Accumulatoren. Accumulatoren var 

 i sin ovre Ende fæstet til et Topréb, hvis anden Ende var 

 fastgjort over Godset paa Storsalingen (Fig. 14.) Med 

 en firskaaren Talje haledes nu Accumulatoren ud paa sin 

 Pia ds under Bagbords Storraa-Nok. Storraaen brasedes 

 saaledes. at Accumulatoren kom omtrent for Midten af 

 Loddebroen, og blev i denne Stilling forstøttet med Braser, 

 Toplenter og Rakke. Lodlinen ihexedes øverste Øjebolt. i

water. Once down. the cylinder is kept in position hy a 

 hook (//). which catches on the under surface of the bottom- 

 piece. The iron fenders (/') at the lower end of the in- 

 strument serve to protect it when striking the bottom, and 

 prevent mud or rubble from fouling tbe stopcock. In lieu 

 of the fenders, we suhstituted an iron rod. having at the 

 lower end an eye-bolt, to which the tube-lead was attached. 

 The apparatus bi - ings up about 2 titres of water. 



Prtfperly used. the Ekman water-bottle gives every 

 satisfaction. There is no leakage: but should any mishap 

 occur in veering, the whole operation will have to he re- 

 peated; moreover, the flange of the cylinder and the disk 

 at the top offer considerable resistance in hauling up the 

 instrument. 



Preparcdions for Deep-sea Sounding. — The sounding- 

 line — length .'li mn fathoms — was wound on the port side 

 of the after-deck on a large, strong reel. secured by screws 

 (Figs. 1. 2. and 14) to the deck. Fig. 13 conveys a 

 clearer idea of tbe arrangement, The 

 barrel of the reel was of wood. 2 feet 

 3 ' i inches long b\ 6 3 ,,, incbes in dia- 

 meter, the two terminal disks being of 

 thick. galvanized sheet-iron. strength- 

 ened on tbe outer surface by a double 

 plating of the same material. They 

 measured 3 feet l 1 ^ inches in diameter. 

 and were rounded at the circumference. 

 so as to give tbem a smootb annular 

 rim. about an iuch broad. At the 

 port end. the reel bad an iron lever- 

 arm, 1 foot in length. with a wooden 

 handle. The two supports of the frame 

 were connected uuderneath by means 

 of iron stavs, the whole apparatus be- 

 ing made to rest on a couple of beams running fore and 

 aft. through which the frame was screwed to the deck. 



The end of the line was run ofl the reel and rove 

 through the leading-block on the after part of the round- 

 house (Fig. 14.) This block was a trifle smaller than the 

 sounding-block and had a solid sheaf. tbougb in other re- 

 spects similarly constructed. From thence the line was 

 rove through the sounding-block. which liung beneath the 

 accumulator. This apparatus was ]attached to a strong 

 pendant, made fast above the gear of the main cross-trees 

 (Fig. 14). and by means of a gun-tackle purchase hauled 

 out under the port main yard-arm, the yard being trimmed 

 so as to bring the accumulator as near as possible abreast 

 of the sounding-bridge. and kept in position by the braces.

 of the operation — was next shackled to the upper eye- 

 bolt of the water-bottle, the ring of the tube-lead. or the 

 ring of the tube of the Baillie machine. When using Willes 

 water-bottle. we liung the sounding-instrument — the tube- 

 lead or the Baillie machine — to the lower eye-bolt, These 

 preparations were made with the vessel steaming ahead;
