The Principles of Agriculture. By William Bland, M.R.A.S. (Long- man

and Co.)—A concise exposition of the reasons for the various pro- cesses of the oldest of arts. Mr. Bland insists much on the necessity of paying due attention to the fallow, and strongly advocates the occa- sional laying down of arable land with grass for two or more years. Generally, however, his object is rather to instil sound principles into the young farmer than to give express rules, which are seldom of much benefit in an art where every different variety of soil requires a dif- ferent treatment. And we think that in this he is very successful. Without any great command over language, he manages always to be clear. We observe that on the much disputed question of leases Mr. Bland is in favour of a fourteen years' term—the farmer to cultivate as he pleases for eleven, and as the landlord pleases for the last three years.
