"The first experiment was conducted in the following manner:--He recommended very young rams to be put to the flock of ewes from which the proprietor wished the greater number of females in their offspring and also, that during the season when the rams were with the ewes, they should have more abundant pasture than the other; while to the flock from which the proprietor wished to obtain male lambs chiefly, he recommended him to put strong and vigorous rams, four or five years old. The following tabular view contains the result of his experiment:-- +----------------------------------+----------------------------------+ | Flock for female lambs. | Flock for male lambs. | +---------------------+------------+----------------------+-----------+ | Age of the mothers. |Sex of the | Age of the mothers. |Sex of the | | | Lambs. | | Lambs. | |---------------------+------+-----+----------------------+------+----+ | |Males.| Fem.| |Males.|Fem.| |Two years, | 14 | 26 |Two years, | 7 | 3 | |Three years, | 16 | 29 |Three years, | 15 | 14 | |Four years, | 5 | 21 |Four years, | 33 | 14 | | | -- | -- | | -- | -- | | Total, | 35 | 76 | Total, | 55 | 31 | |Five years and older,| 18 | 8 |Five years and older, | 25 | 24 | | | -- | -- | | -- | -- | | Total, | 53 | 84 | Total, | 80 | 55 | | | | |N.B.--There were three twin-births|N.B.--There were no twin-births | |in this flock.
