1. Trawling Operations in Luce Bay.

 steamer "John Fell" to trawl in Luce Bay for the

 weather was all that could be desired, and the trip was 

 made without any trouble ; but the second trip was 

 unfortunately deferred until December, and as very 

 unfavourable weather was experienced time was lost. The 

 trip was a most unpleasant one, and the results were not 

 nearly so successful as they might otherwise have been. 



On 12th October, one haul was made with the shrimp 

 trawl : the net was one with a half-inch mesh bent on to 

 a 30 feet beam. There was no object in making this haul
