I recommend, absolutely without reserve, a war book entitled _Day by Day with the Russian Army_ (CONSTABLE). It is written by Professor BERNARD PARES, the Official British Observer with the Russian Armies in the Field, and is the real thing. Although incidentally it is to be praised as a modest and lucid piece of writing, well in keeping with the character of an author whose habit of viewing an action from the most dangerous, because the most interesting, point can be discovered only by reading between the lines, primarily it is to be prescribed as a sovereign tonic against German-made depression. The writer, after being present at the conquest of Galicia and the triumphant advance to the top of the Carpathians, after witnessing much of the historical Russian retreat under pressure of overwhelming artillery superiority, and after conversing freely with his friends of all ranks on different sectors of the Front whilst offering greetings in the name of their English comrades in arms, announces finally, in a wholly satisfactory fashion, his unalterable conviction as to the unqualified supremacy of our Allies when on anything like equal terms with their opponents as regards munitions of war. And that is a matter which, though never in doubt, it is pleasant to hear again in tones of authority at a time when we believe the Russian lack of supplies is at last being made good. The evidence is the more complete because not only do we learn of the interrogation of many prisoners, but because a long extract from the diary of one of them, an Austrian officer, is included, to point the difference in spirit between the two armies. The demoralisation of the Austrian forces, even when advancing, is so strikingly presented that one cannot doubt their dependence on German domination and German batteries to hold them together at all. Although Professor PARES attaches several excellent maps, he is not really much concerned with questions of strategy, but has devoted himself to just two points--_moral_ and munitions. * * * * *
