long, covered with netting of meshes of 10 millemetres, with entries at 

 the ends to the suspended bait (fragments of fish). The framework 

 has stones tied to it, and the cage or pot is furnished with 40 metres of 

 line and a cork at the end. Each owner has at least 25 or 30 pots which 

 he places in favourable reaches, at depths of 15 to 30 metres more or 

 less distant from the coast, preferably on muddy bottoms where 

 vegetation grows. The use of these pots or cages is prohibited between 

 1st November and 1st May. A hundred boats with 300 fishermen 

 pursue the fishing. The mean product is 80,000 kilogrammes annually, of a 

 gross value of 220,000 francs, and net 200,000 francs, giving 2000 francs 

 per boat. Another mode in use in the north of France, near Cherbourg, 

 is to employ a machine more like a lobster pot, and very open. It is more 

 productive than the last, but as the shrimps can easily escape, the fishermen 

 are obliged to remain with their boats over night drawing and resetting 

 the traps. 



Yet another system is employed on the littoral of La Vendee, where a 

 conical net 40 to 60 centimetres deep, with lOmillemetre meshes, is fixed 

 to an iron circle of 80 centimentres to a metre, like a very open butterfly 

 net. The bait is laid on the bottom of the net, the bridle kept clear of 

 it by a light float, and with 10 to 20 of these per boat they are lifted 

 every ten minutes. They are most destructive where there are sandy 

 stretches between rocks where trawls could not go. 



The consulting Committee of Maritime Fisheries submit the following 

 conclusions : — 



1. The adoption of the measure already proposed, which consists in inter- 

 dicting, at all times and in every place, the use of the shrimp trawl ; 

 the promptest possible notification of this decision ; the fixing, for 

 applying this interdict, a delay of a year, starting from the day of the 

 notification. 



2. To popularise the system, other than the trawl, employed for the 

 capture of the shrimps by boat, by distributing descriptions of these 

 appliances, particularly of those in use at Croisie and Saint-Gilles-sur-Vic ; 

 gratuitous distribution of a certain number of samples of the machines 

 employed in order to make the model known and so encourage its trial. 



3. The substitution of steam vessels in place of the coastguard ships 

 actually charged with supervision of the coast fisheries. 



Prince Albert of Monaco has been good enough to send a number of 

 pamphlets, giving some of the results of four scientific cruises in his 

 yacht 4 Hirondelle.' They contain discussions on the currents of the 

 Atlantic, which have been investigated in a thoroughly practical manner. 

 The Prince, in order to determine the direction of the currents, set 

 numbers of floating objects adrift, with directions to the finder where 

 they were to be forwarded to. By a careful system of number, dates, &c. 

 a vast amount of data is gradually being accumulated on the subject of 

 ocean circulation. 



Various kinds of apparatus have been made for facilitating marine 

 researches, such as the capture of animals in certain kinds of traps, and 

 the attraction of marine animals by means of the illumination by 

 electricity of the deep water. He has described the sperm-whale of the 

 Azores, and two specimens of OrtJiagoriscus mola, taken during the 

 voyages in 1886 and 1887. During the second voyage he obtained, off the 

 Spanish coast, Julis vulgaris Cuv. et. Val., Labrus bergylta, Asc, Conger 

 vulgaris, Cuv., and Gadus luscus, L. Prince Albert describes a self 

 registering thermometer which he employed for taking temperatures at 

 great depths, and in the paper on his third voyage he gives a note of the
