The annual rainfall for the whole of France averages about 32 in.

The chief wheat lands are in Victoria, South Australia and New South Wales; the yield averages about 9 bushels to the acre; this low average is due to the endeavour of settlers on new lands to cultivate larger areas than their resources can effectively deal with; the introduction of scientific farming should almost double the yield.
The rainfall is very unequally distributed: in the western part, which comes near to the limits of the rainless region of Asia, it is very scanty, and scarcely averages more than 5 in.; in the south-west the fall is more copious, sometimes exceeding 100 in.
The proportion of ground under olives is from 20 to 36% at Porto Maurizio, and in Reggio, Lecce, Ban, Chieti and Leghorn it averages from 10 to 19%.
