Professor Lowrie, of Roseworthy Agricultural College, South Australia, m a lecture, contended that sheep afforded farmers many advantages, amongst which was means of cleaning the land. Sheep nipped off and prevented weeds from seeding. In light land nothing would keep it clean better than sheep. On the question of sheep enriching the land, the professor took his stand on the side of the affirmative. He did not lose sight of the fact that every pound of bone took away so much phosphoric acid, that each fleece of wool carried away 40 per cent of potash ; and that every pound of mutton took away the most valuable constituent, nitrogen, m large percentage. There was such a thing ;w temporary' exhaustion, but not the thinnest of the soils had been exhausted beyond recovery. While sheep were grazing the atmospheric agencies were a.t work, and they were liberating a greater supply of plant food than was carried away m the carcases and wool of theS'Sheep.
