THIi EVKRVnAY LIFE OF TIIK LOBSTEB. While our lobster-rearing experiments at Long Beach pond, both last year and this, resulted in failure, it cannot be said that the two seasons' work was entirely barren of results. Apart from the observations which have been made on mating, and which, it is hoped, may prove even more useful to the lobster industry than any success which might have been achieved in lobster rearing, we have been able to make some contribu- tions to our knowledge of the every day life of the lobster. Very early in our operations of this year it was decided to use but two rearing boxes, instead of four. The other two were fitted up with shelters, or nests, for the study of adults. Obeservations were made every day from July 30 to August 6, when the animals had to be removed. The excesive leakage from the pound left our boxes resting in the mud, and contributed not a little to bring aUput the death of several adults, through the lack of properly aerated water. POSTURES. When jierforminB certain functions, for example, cleaning themselves, egg-laying, fighting, etc., the adults took up certain appropriate iwstures. One of these, which may be »i)oken of as the cleaning posture, was first observed among lobsters which had wintered in either pond or pound. Within a week after these animals had been placed.
