Man slåp Tampen af Enden, væltede Vægten overbord, og denne Iøb da med Kousen. nedover langs Touget, imltil den standsedes af den paasatte Trætærs. Dette kunde toles, naar man holdt Haanden paa Touget. Skibet lan nu stille, medens Lodder og Skrabe sank. Vi regnede, etter flere Forsøg, at der behøvedes 12 Minut- ter for at Skraben skulde synke 100 Favne. Skrabens (eller rettere Trawlens) og Loddernes Synkning er anskue- not less than double the deptb. nay for smaller depths even more. The engine was now stopped, after vvhich we hauled in the dredge-rope, as before, to the taffrail. and kept it up in a bight of ropes end. With the lizard was then made fast to the wooden thimble a weight proportioned to the depth. consisting of 3 or 4. and for the deepest dredg- ings, of as many as li of the sinkers of the Baillie sound- ing-machine. weighing each 55 pounds. We now. after let- ting go the rope. tilted the weight overboard. wbich spun down along it till stopped by the wooden toggle. The shock of its arrest was distinctly perceptible to a person who bad his hand on the rope. The vessel was now kept stationary, while the weight and the dredge were sinking. After some expe- rience. we calculated the time required for the dredge to sink lou fathoins. to be about \'2 minutes. Fig. 20 will. Fig. 20, liggjort i Fig. 20.
