Leaves 56 in-calf hinds, or 56 born to 100 hinds. (About 33/ ) deduct 19 dead by end of February. Leaves 37 calves alive in February, produced by 100 hinds. This calculation shows that about one-third part of the calves born to i oo hinds died before we made our count, that is to say these died during the first eight months, leaving 37 calves alive by count of 1890 to 100 hinds. Out of the residue (37 calves) our death lists show one-fifth part more usually fails to enter the second year of existence. Consequently, taking 37 calves alive in Feb. as a basis, 100 hinds produce 29-4 year-old deer. Our tables are mostly on the basis of 35 calves to 100 hinds, which brings out a result of 28 year-old deer as the produce of 100 hinds, and as the births are 56, it follows that half the 38 calves die before they enter the second year, if we take basis of 35 calves alive in Feb. to 100 hinds. We do not pretend to know accurately the proportion of young to adult hinds, neither do we know exactly the proportion of yeld hinds among the adults, but this table cannot be very far wide of of the truth. The conditions of deer in an enclosure, or park, would be altogether different. This concludes the chief things I have to say about the Jura deer. Our calculations and estimates, and most of the paper may be called "Guesses at Truth." We have travelled without much track to lead us, except our own observations ; an Island however
