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.

The Tree of Heaven (CASSELL) spread its friendly branches over a pleasant corner of a roomy Hampstead garden.  Matter-of-fact Anthony, the timber merchant, always would insist that it was a mere common ash; but the others, Frances, and the children, Dorothy, Michael, Nicky and adopted Veronica, knew better, as also, no doubt, did Jane-Pussy and her little son, Jerry, who was Nicky’s most especial pal.  Miss MAY SINCLAIR, without being a conscienceless sentimentalist, does us the fine service of reminding us that the world of men is not all drab ugliness, but that there are beautiful human relationships and unselfish characters, and wholesome training which justifies itself in the day of trial.  She divides her charming chronicle into three parts—­Peace, The Vortex, and Victory.  The first deals with the childhood of the happy brood of Anthony and Frances, delicate studies subtly differentiated.  Even the little cats have their astonishing individuality, and I don’t envy anyone who can read of Jerry’s death and Nicky’s grief without a gulp.  The Vortex is—­no, not the War; that comes later—­but the trials of a world which tests adolescence, a world of suffrage rebellions, of Futuristic art and morals.  Then the real vortex of the War, the Victory which means ready (or difficult, unready) sacrifice and death for the boys and their friends and as great a sacrifice and as cruel a thing as death for the others, the women and the elders....  A novel, which is much more than a novel, packed with beauty and sincerity, setting forth its tragedy without false glamour or shallow consolations.
