Of the carcases of the dead animals he makes the present men (N.
I I) and Necrophaga are valuable scavengers from their habit of burying small vertebrate carcases which may serve as food for their larvae.
The cattle and sheep entered for this competition are shown alive on the first day, at the close of which they are slaughtered and the carcases hung up for exhibition, with details of live and dead weights.
The competition thus constitutes what is termed a " block test," and it is instructive in affording the opportunity of seeing the quality of the carcases furnished by the several animals, and in particular the relative proportion and distribution of fat and lean meat.
The live animals are judged and subsequently the carcases, and, though the results sometimes agree, more often they do not.
