 The niesbes of these nets are either huge, to allow the small fish to slip 

 through, or tliey are narrow, so that even small fish cannot pass through. 

 2. The seine is a net of varying size, with wide meshes, and consist- 

 ing of one or two ])ieces ; along its entire length inns a r()i>e holh above 

 and below, the lower one being weighed down with ])ieces <il" lead or 

 stones attached to it at iidervals of about 30 centimeters, -while the uj)- 

 per one has at similar intervals pieces of cork, which keeps the upper 

 part of the net floating in the water while the lower part rests on the 

 bottom. In order to haul the seine to advantage it niust be as long as 

 the sheet of water in which the tisheries are to occur, and broad enough 

 to exceed its depth by one-fourth of its breadth, so that it can bulge 

 out and make folds, which is necessary to a successiul haul. 



At each corner of the net a string is fastened, which is made movable 

 by means of a piece of wood. These strings, called arms, are necessary 

 to enable the men to haul the net with a full exertion of all their strength. 

 When the seine is pulled when in the water a largo bulging fold is 

 formed in which the fish gather, so the fishermen have only to draw the 

 lower and upper jope together. To clean a pond of fish with this ap- 

 I)aratus, it is essential that the bottom where the fisheries are carried 

 oil shoidd be even, so that the seine may in its entire length rest on the 

 l»()ttom and that no fish can slip away underneath it. The hauling of 

 the seine will always rcipiire several i)ersons, and sometimes a boat. In 

 the latter case the boat is manned by three pert-ons, while three remain 

 on shore and hold on to one arm of the seine. While two of the nn^n in 

 the l)oat row towards the place where the fishing water begins (as far as 

 the water will carry the boat), the third one lays the seine in the water. 

 As soon as the men in the boat have reached the place where the water 

 begins the men on the shore begin to pull the arms of the seine and drag 

 it on land in a semicircle, while the boat is gradually approaching the 

 shore, the men in it drawing the seine as far towards them and into the 

 boat as is necessarv to get the fish together in the trough formed by the
