The criticism has also been made at the International 

 Council, we are told, that our two exactly similar surface 

 nets fishing at the same time and catching somewhat 

 different gatherings were probably one on the windward 

 and the other on the leeward side of the ship working 

 under very different conditions, and so could not be 

 expected to yield comparable results. We can at once 

 remove that objection by stating that that is not the case. 

 When working the surface nets the ship is put head to 

 wind and steams very slowly against any wind there may 

 be ; so there is no windward side, and the two nets in 

 question are worked from the stern, side-by-side, and are, 

 so far as can be ascertained, under similar conditions. 



Old and New Nets.

 rapidly the meshes of the fine No. 20 silk became clogged,
