An intelligent man or woman willing to make a career of reviewing fiction is hard to come by... And the temporaries do the work cheaply. Moreover, continuity may be got at the expense of intellectual arthritis; a reviewer who has been at his grisly task for half a lifetime may stiffen into prejudices of every sort, and become too anchylosed to do better than turn his back to a new wave when it rushes down on him.
