Seamen wielding nets: Rutherford and Drayer 
Used same 100 watt light with shade-but turned 
light on its side so that it threw the beam laterall; 
along the sideof the gangway-this was a much more 
satisfactory arrangement, for it liranught to the 
surfacemany of the fishes which had previo. sly bear 
just beyond the reach of the net. However there 
are still many fishes which are down 5-10 feet below! 
the light-which would be available if a fine- 
netted bait net of about 12 ft diameter were avail¬ 
able immediately beneath the light-so shall 
see if such a net cannot be constructed, j 
Fishes collected: or an average of $7,5 
per man net per hour 
The increase in the number of fishes was due 
to change in position of the Eeflector light-for 
now it is used with the light beam directed parralel 
to the surface -thus bring up the large numbers 
of small fishes which had previously been just out 
of reach.
