At this date "The Junior Sub" fortunately needs no introduction to a public that has long gathered him and his to its appreciative heart. I should not like to guess how many people read and enjoyed _The First Hundred Thousand_; they all, and more, will delight in the appearance of _Carrying On_ (BLACKWOOD), in which the exploits of the famous regiment, of _Major Wagstaffe_ and _Captain Bobby Little_ and the rest of them are continued. What the precise war position of IAN HAY may be by now I am unaware, but I should emphatically suggest his appointment to the post of Official Cheerer-Up. Perhaps (how shall I put it?) the eye-pieces of the writer's mask are a trifle too rose-coloured for strict realism; great-hearted gentlemen as we know our heroes to be, are they always quite so merry and bright as here? One can but hope so. In any case, as special propaganda on the part of the O.C.U., the stories could hardly be bettered. One, called "The Push that Failed," I would order to be read aloud to the workers in every munition factory in the land; its heartening tale of how the British people had, to the paralysed astonishment of Brother Bosch, "delivered the goods" to such effect that his projected spectacular attack under the eyes of WILLIAM the Worst was smashed before it began, is of a kind to strengthen the most weary arm. While I was yet upon the final page the bells in a famous abbey tower close by broke into grateful clamour for the news of victory. But IAN HAY does not wait on victory; he has his joy-bells ringing always in our hearts. * * * * *
