fast paa Rullen agterud, hvor 2 Mænd stode færdige til 

 at bremse. Derpaa kommanderedes ..Lad gaa"! og Lod- 

 ningen udførtes som ovenfor for Rør-Loddet beskrevet. 



Ddfiringen af BaiLLie-Maskinen til 200 eller 300 Fav- 

 nes I hb. før man lader gaa, er nødvendig paa, Grund af 

 den store Vægt, Lodlinen har at bære, og som vilde gjøre 

 det umuligt med de havende Bremsemidler at kunne regu- 

 lere Linens Bevægelse. I >e 200 til 300 Favne Lodline, 

 der ved Operationens Begyndelse allerede er i Våndet, giver 

 saamegen Friktion, at det er Bremserne muligt, om end 

 med Anstrængelse, at holde Rullens og Linens Bevægelse 

 under Kontrol. 



Ved Lodning paa større Dyb er det ikke saa let at 

 iagttage det Øjeblik, da Loddet uaar Bund, som ved min- 

 dre Dybder. Linen lægger sig ikke ned i Dækket, men 

 vedbliver at løbe fra Rullen, etterat Loddet er i Bund. med 

 en Hastighed, der ofte kun er lidet mindre end under 

 Loddets Synken. Ved med udelt Opmærksomhed at følge 

 Linens Fart. navnlig dens Bevægelse gjennem Loddeblok- 

 ken under Accumulatoren, har man imidlertid et næsten 

 altid sikkert Middel til at observere Øjeblikket, naar Lod- 

 det slaar i Bund: man ser da nemlig Blokskivens Rota- 

 tionshastighed pludselig formindsket. En første Kontrol har 

 man strax deri. at Slakken af Lodlinen nu kan hales ind 

 med Haandmagt, medens det, saalænge Loddet løber, i 

 Regelen vil vise sig ugjørligt ved Haandmagt at staiulse 

 Bevægelsen. Den sædvanlige Kontrol med Notering af 

 Klokkeslet for hvert Hundredefavnsmærke, som gaar i 

 Våndet, anvendtes jevnlig. Den sidste Kontrol havdes en- 

 delig deri. at Accumulatoren i det Øjeblik. Lodroret (og 

 Vandhenteren) løftedes af Bunden, tydelig strakte sig ud. 

 Fra dette' Øjeblik begyndte man. som ovenfor beskrevet, at 

 maale Favnetallet over sidst udløbne Mærke. Naar Øje- 

 blikket. da Loddet slog i Bund. var utvivlsomt at iagttage 

 paa den udlobende Line. viste Methoden med Tidsinterval- 

 ler for hver 100 udløbne Favne sig ulige paalideligere ved 

 Baillie-Maskinen end ved Rorloddet.

of line with the donkey-engine. The engine was now stop- 



ped. the ture part of the line secured with a stopper to an 

 eye-bolt on the deck ut' the roundhouse, and the after part 

 removed from the drums and fcightly wound mi the reel 

 aft. where a couple of men stood ready to commence bra- 

 king. The word being now given to let go, the operation 

 was carried out in the manner described above for sounding 

 .with the tube-lead. 



Veering the apparatus 200 or 300 fathoms prepara- 

 tory to letting go, was indispensible with the Baillie ma- 

 chine. owing to the great strain upon the sounding-line, 

 the motion of which would otherwise have been impossible 

 to regulate with the nieans of braking at our disposal. 

 The friction of the 200 or 300 fathoms of line in the wa- 

 ter at the beginhing of the operation. enable the brakes- 

 men, thoiigh with some Little exertion, to command tbe 

 revolutions of tbe reel and the motion of the line. 



When sounding in greater depths, it is by no means 

 so easy as in water comparatively shallow to tell the exact 

 moment at which the lead touches the bottom. The line 

 will not drop flat on the deck. but go on running off the reel, 

 even attei' the lead has reached the bottom, and with a 

 velocity but very Little inferior to that it bad during the 

 descent of the lead. Meanwhile, hy closely noting the 

 speed of the line. in particular where it passes through 

 the sounding-block below the accumulator, we have, in the 

 great majority of cases, a sure means of accurately deter- 

 mining the moment when the lead strikes the bottom, the 

 rotation of the sheaf of the block becomhiL! instantly slower. 

 Moreover, the slack part of the line - can then be readily 

 brought in by hand. whereas so long as the lead is sinking, 

 it will. as a rule. be found impossible to check its motion 

 by physical strength alone. The usual mode of measure- 

 ment. by noting down the exact time at which each of the 

 300 fathom slips entered the water, was frequently adopted. 

 As a final resort, we liad the test afforded by the visible 

 extension of the accumulator the instant the sounding-tube 

 and the water-bottle were lifted from the bottom. We 

 then. as stated above, immediately began to measure off 

 the number of fathoms run out after the last slip bad en- 

 tered the water. Provided the arrest of the weight at the 

 bottom could be accurately determined by observing the 

 velocity of tbe line. the method of measuring by time-inter- 

 vals. for every 100 fathoms run out. was found to be far 

 more trustworthy with the Baillie machine than with the 

 tube-leacl.
