Winter. Boston: L. C. Page&Co., 1911. 8vo.; 421 pp.; illustrated. Price, $3. Argentina, like the other countries of South America, has received far less consideration than it is entit l ed to. One of the greatc'st food-producing conn tries of the globe, qlH-'tn or the Suuth American republics, first among thell all in import and export trade, with a capital ranking as one of the greatest citin of tlh world, Argent ! llu must quidH'll the lluIsf' of all who ar( atlractpd by the new, the progressive, the resourclful, and the ambitious. lYe have in the volume lefore us, to use the author's own designation, “an account of the customs, characteristics, amusements, history and advaneement of the Argentinians , and thl development a1 rfSOUICes of their country.” It is a brightly - w I'il lc'n and Well-made volume enriched by charming vipws and illus trations. KoRth Devon with West Somelset. By-Beatrice and Gordon Home. New York: Frederick Warne&Co. 12mo.; 220 pp.; illustrated. ''his is a little volume to fit the pocket, con taining some very good views of the countlyside, coast scenery, and pictlllesque buildings. The part of England with which it deals has an exceptional and distinctive beanty, as ev(ryonp knows. Such nantes as CovelJy, JIfl'ucombe, and Exmoor conjure up pictures of appealing quaintness, glimpses of rugged promontories and far-flung hays lying in purplish light, and stretches of wild mour and wild-blown spaces. We are now in the land of Lorna Doone and her “girt Jan nidd.” The book is not a ster('otyped guide, although its large-scale maps Rligllt nothing, but is almost like a gift-book in style and make - np-would, indeed, admirably serve that purpose-and is full of sympathetic de scription and discriminating illustration. Homestead. The Housflholds of a Mill Town. By Margaret 10 BYington. New York: Charities Publication Committee, 1910. 8vo.; 292 pp. Price, $1.50; postage, 20 cents. Homestead is a town. Homestead is also the mill which perpetnates the towu. But 2iargaret Byington's hook is mainly of the home life the mill town l('adR on the wages whieh the mil! pays. It is a comIunity at working men, repres(nting an parly 'euton· Celtic wave of immigration and a later Slavic lntlux. I'erhaps the main interest of the survey (' enters on “life at $1.65 a day.” We arf not so much drawn to a stUdy of middle-class living and humdrum resppctability. Ouq literature must give us either the prince or | the pauper—either Brewster's millions or the I w.dow's nute. “ese nme-dol lars-a-we ek m(n I wrth wives and familips can allow themselves · IJllt twenty-two (,pnts ]pr man for a day's food.! The Committee on Trade and Commerce estl-I mat",l that in Pittsburgl.l a liberal provlslOn of food for a fam.ly of five could not be PUl -chased for less than $11.88 per week. From th('s!' contrasting fgures we may draw our own conclusions as to the uuenviable state of the unskilled work(r in the steel mills. Rents are high. The twelve-hour day, continu('d in many cases through the seven days of the we('I, leaves no time for anything else save food, a pipeful of consolation, and sleep. This is of course the shadow of the picture, tlH'l'e are ligher lights. The yolure is one of the six which comprise the notable Pittsburgli Survey findings, and Is remarkable for tIll way in which it goes to the very heart of things and tabuiatps human strivings, ]ongingH , and lim.tatiollK in column: of cold type.

Experimental Work. In point of publisher's technique the book deserves the highest praise, and there is a wealth of fully written out structural formulae. Th e tn'utm ent of the subject leaves nothing to be desired. A nU lllb"r of new prints an an occasional loughncss in literary style should be ditn'ina tpd by tension in a later pdition. A cUiiols omission ot'L'urs in the index, which, und"l” the entry “Indigo,” fails to give the most important l'efel'l'nee, nalnely, that to the chapter on Indigo on page 37G.

By William Jackson. New York: Spon&Chamberlain, 1911. 12mo.; 164 pp. Price, $1.

As it is ilposilJle to find many such t(>('hnical na les in the ordinary dietionul'Y, this eompilation should promote ease of comlJll'reial intel'course and find favor with a large class of buyers and shippers here and abruad. Between three and four thousand words and phrases are alphabetically listpd. How to Make a Wm!less Set. By Arthur Moore. Chicago: Popu ar Mechanics Company, 1911. 12mo.; 84 pp.; illustrated.

New York: John Lane Company, 1911. 8vo.; 101 pp. Price, $1 net; postage, 8 cents. The rose is everybody's favorite, symbolical of all the beauty and fvagrance of life. Almost any soil can be made to grow roses of one kind or another. The various soils and their preparation forms the theme of the first two chapters. The question of planting is argued. and budding, sowing, and striking as methods of propagation are examined with thoroughness. Much space is given to describing the YarietiEs-wiId, autulll blooming, decorativC, and climbing roses. 'he full-page plates will delight the heart of the flower lover, for they s(em almost to exhale the perfume or the specimens they picture. The ambition of every tiremaker in the world is to some day make a non-skid tire as good, and as popular as the famous NOBBY TREAD Eighteen months ago, Nobby Treads were first placed on the market. Since then they have been sweeping the country, replacing every form of non-skid tire or non skid device on cars in every state iu the Union, and in every possible kind of service. Skidding Protection - These Lig, thick. diagonally pliced knobs grip the slippenest road or pavement at every possible angle. They hold th,e wheel against skidding, and drive slipping” even on a wet asphalt pavement. They reach down deep into muddy or saudy roads. and hold the whfd secure where a plain tread \ouJd spill around unhindered. Wearing Quality-In decided contrast to the ordinary, so-called. non-skid tires, those tough rubber knobs expose so large a surface to the wear and lear of the road that it takes thousands of miles of the hanlest kind of serVice to wear them smooth. When they finally do wear dOWII, a plain tread still remains good for many more miles of service.
