SOME REFERENCE BOOKS

Now that the hounds of spring are on winter's traces, we turn with pleasure to page 20 of the excellent Road Atlas-Guide to Great Britain, issued by Messrs. Philip at 3s. 6d., and trace our route out of London down the Old Kent Road to the Sussex downs, where we fain would be. We have not seen a dearer or better arranged guide for motorists in so small a compass and we cordially recommend this pocket volume.

Volume VII of Chambers's Encyclopaedia (Chambers, 20s.) takes us through all the paths of human activity from " Man- chester " to " pennywort." This is a really up-to-date encyclopaedia. We do not pretend to have read it all, but the article on patents, which we selected as a test, is very well written and full of recent information. 31,370 applications were made for patents in Great Britain during 1924, and 16,839 were granted. In the United' States of America the numbers were 76,855 and 42,594 respectively, which shows that the inventive urge is stronger, making allowances for difference in population, on the other side of the Atlantic.

We have received Volume III of Palgrave's Dictionary of Political Economy (Macmillan, 36s.), which we commend as cordially as the former excellent volumes. This dictionary gives under separate heads an account of the principal writers on' Political Economy and the characteristics of the different schools of economic thought. Every reference library should include this valuable work.
