Haddon and GrREEN — Secoud Report on Irish Marine Fauna. 47 
1886, and in order that all things should be ready by that time I com- 
menced preparations in the month of January. Correspondence with 
various manufacturers of material occupied no little time, so that in 
the end I found that I had not commenced work a day too soon. The 
result has shown that rapidity of action and efficiency in gathering 
objects were gained to a considerable extent. The details of construc- 
tion and working of apparatus will now be given. 
The ''Loed Bandon." 
The steam-tug ''Lord Eandon," which we were able to hire from 
the Clyde Shipping Company, is a paddle steamer of the following 
dimensions : — 
Length, . . . . . . 122 feet. 
Ereadth, 19 „ 
Depth from deck to bottom of hold, . 10 „ 
Gross tonnage, 154 tons. 
Two engines, side lever, surface- condensing cylinders, 30f " ; length of 
stroke, 54"; horse-power, 95 (nominal) ; two boilers. 
Steam Windlass. — This steam windlass was altered to meet our re- 
quirements in the following manner: — On the intermediate spindle a 
small surging drum was fixed, which revolved at a high rate of speed, 
and so enabled us to wind in our dredge rope at a rate of 50 fathoms 
per minute when the strain was not too great. On the lower spindle 
a very large iron surging drum was fixed ; this was about four feet in 
circumference, and well calculated for winding the steel rope without 
injury. 
Towing Sheave. — Over the stem projected two beams of wood, sup- 
porting a large iron sheave on which the dredge rope worked ; the rope 
passed from this to the bridge, over which it was conducted on rollers 
to the donkey-engine ; it passed thence to the iron reel which was fas- 
tened to the deck beneath the bridge. Close to the towing sheave in 
the stern a Derrick was constructed ; this proved most useful for lifting 
the trawls and dredges on board. 
The steam-whistle in front of the fore-funnel was utilized for sig- 
nals from the stern (where one hand kept watch over the dredge rope) 
to the men at the donkey-engine in the bow. This was done by a long 
cord from the whistle to the stern Derrick : one blast meant stop" ; 
and, if stopped, one meant ''go on heaving."
