monidae and other fishes. The eggs of the lobster might be 

 similarly spread out upon trays or grids, allowing the 

 free percolation of well-oxygenated water> and intelligent 

 supervision being at hand in the same way to remove 

 all dead examples or other deleterious matters. Or 

 nature itself would be yet more nearly imitated if the 

 groups of eggs, numbering many hundreds, as attached to 

 the swimmarets of the parent, were bodily removed, and 

 by some simple device suspended in grape-like clusters 

 within the midst of the circulating currents. The young 

 lobsters being hatched, they will be found to thrive best in 

 deeper receptacles where they will have abundant room 

 to swim. The font-like rearing troughs introduced by Mr. 

 Oldham Chambers, F.L.S., the goblet-shaped glasses utilised 

 by the Canadian pisciculturists, but more especially the 

 larger glasses on the " intermittent syphon system " and 

 other hatching receptacles for floating spawn made use of 

 by the United States Fisheries Commission, may be cited 

 as being particularly suitable for lobster rearing.* Feeding 

 the young brood is obviously a mere matter of mechanical 

 detail, finely-minced fish or mussels being the most con- 

 venient pabulum. Whatever is decided on, due attention 

 must be paid to the food being supplied abundantly and 

 regularly, otherwise they will fight and devour one another. 

 The well-known pugnacity and reputed cannibalistic tend- 

 encies of lobsters and other Crustacea has been supposed 



* I here take the opportunity of acknowledging the kind courtesy 

 shown me by Mr. Earll of the United States Fisheries Commission in 

 introducing and explaining to me the very complete collection of hatch- 

 ing and rearing tanks exhibited on behalf of the United States Govern- 

 ment in their department of the International Fisheries Exhibition. 

 Such inspection, it may be added, resulted in that gentleman's con- 

 currence with my own opinion, that the receptacles on the " inter, 

 mittent syphon system " were especially adapted for lobster culture.
