It is only a guess on my part, but one founded on considerable travel and observation, which makes not more than one-third of this extent--say thirty millions of acres--properly arable; the residue being either ruggedly mountainous, hopelessly desert, or absorbed in the tulé marshes which line the San Joaquin and perhaps some other rivers. The arable thirty millions of acres --nearly the area of all New England, except Maine-- are scarcely equaled in capacity of production by any like area on earth.

All the fruits of the temperate zone are grown here in great luxuriance and perfection, together with the fig, olive, etc., to which the lemon and orange may be added in the south. No other land on earth produces wheat, rye,
