 The leadfc common multiple of the numbers is 3000. 
 The required number of acres is 3000, 600, 9000, <kc. 
 (4.) Arts. 53 and 56. (5.) 360. (6.) Art 38. (7.) The 
 numbers, when resolved, are 2^. 3. 13. 53., 2^. 3^. 13. 
 43., 23. 3. 13. 443, and 26. 32. I32 : of which the G. C. 
 M. is 23. 3. 13, and the L. 0. M. is 2«. 32. I32. 43. 53. 
 443. (8.) The prime factors of 1680 are 2^. 3. 5. 7. ; 
 the four numbers are therefore 5, 6, 7 & 8. (9.) A 
 would go once round the island in G00-i-20=30 days, B 
 in 600-4-30=20 days, C in 600-^25=24 days, and D 
 in 600^40=15 days. By finding a common multiple 
 of these, we shall have the time in which — after each 
 one had gone several times round the island — all would 
 be together again at the point from which they started. 
 The least common multiple of 20, 20, 24 and 15 is 120 ; 
 hence the travellers would come together i^ 120 days.

 nearest to 77 yards is 99 times the length of the mea-

 (9.) Any finite fraction can only be said to be equal or 
 equivalent to the infinite repeating decimal, as the limit 
 of the value which the decimal can never exceed. It 
 may easily be shown that the more figures of decimal 
 are taken, the larger the decimal becomes, and will 
 continue to approach in actual value to the fraction, but 
 within a difference less than can be assigned by any 
 fraction whatever. (10.) This fraction having the factor 
 7 in the denominator, is apparently one which will pro- 
 duce a repeating decimal, but when the fraction is re- 
 duced to its lowest terms, the denominator consists of 
 factors each equal to 2. Repeating 0; Non-repeating 11.

 (1.) (1) By comparing the work done by A and C in 1 
 day with that done by A and B in 1 day, we find that C 
 does as much as B + y^^ of the work : and substituting 
 this value of C in what B and do in 1 day, we find 
 what B does in 1 day, and in 2jjf days he will do 2|j^ 
 times as much as in 1 dav, and be entitled to that fraction 
 of the whole pay. (2) Jp'ind what fraction of the whole 
 pay B might have obtained ; then the former fraction 
 minus the latter - $2 ; from this the whole pay or 1 may 
 be obtained. (2.) The amount to be received equals the

 The rate,% here will be found to be 6. (5.) Let 1 be

 (6.) Since he has to pay J% commission, the stock is only

 money he gets £4 income, or $(4 x -^ x y^§) for every

 transferring. Then, if he can afford to pay $(104 x -Y- x

 more or less in order to get $6 1 And, deducting |-% 
 commission from this result gives the amount which he 
 can afford to pay for every $100 stock in order that no 
 change may occur in his income. (7.) Let the distance 
 rowed be 1 ; the difference between the distance rowed

 But the watch gains 2' on every 24 hours ; having 
 found, then, the correct time which it takes him to row 
 down and up, by a similar analysis to the above, the 
 whole distance, or 1, may be determined, and the difference

 . . . The work is divided into six chapters. The first is on tho 
 Unitary Method, and (;ives solutions showing its application to a 
 variety of prohlems, in Simple and Compound Proportion ; Percentage, 
 Interest, Discount, Profit and Loss; Proportional Part«, Partnership; 
 Chain Rule, Exchange, Alligation ; Commission, Insurance, &c., 
 Btocks ; and Miscellaneous Problems. The second is on Elementary 
 Rules, Measures and Multiples, Vulgar and Decimal Fractions. Ihe 
 third contains Examination Papers for entrance into High Schools and 
 Collegiate Institutes, the fourth for candidates for third-class certifi- 
 cates, the fifth for candidates for the Intermediate Examination and 
 second-class certificates, and the sixth for candidates for third-clasi, 
 certificates and University Honours. It will be observed that the work 
 begins with the fundamental rules— those principles to be acquired 
 when a pupil first enters upon the study of Arithmetic, and carries 
 him forward till prepared for the highest class of certificates and for 
 Honours of the University. . . . Teachers will find in it a necessary 
 help in supplying questions to give their classes. Those who aspire to 
 be teachers cannot have a better guide— indeed there is not so good a 
 one— on the subject with which it is occupied. 
 
 From the ADVERTISER. 
 
 ... By all who are groping after some method better than 
 they have at present, this volume will be cordially welcomed, and 
 many who have never suspected the possibility of accomplishing so 
 much by independent methods, will be, by a perusal of the introduc- 
 tory chapter, impelled to think for themselves, and enabled to teach 
 their pupils how to do so. . . . It is far superior to anything of the 
 kind ever introduced into this country. . . . Tho typographical 
 appearance of the work is of a very high character— quite equal, in 
 fact, to anything of the kind issued by the best publishing houses of 
 London or New York. 
 
 From tho TELESCOPE. 
 
 . . . The plan of tho work is excellent, tlie exercises being 
 arranged progressively, each series preparing the student for the next. 
 The problems are all oriarinal, and so constructed as to prevent the 
 student usin^- any purely mechanical methods of folution. . . . We 
 should really feel proud of our Canadian Authors and publishing 
 houses, when wo consider tho infancy of our country and the progress 
 It has made and is making in educational matters, ana particularly In

 I4iave been very much pleased by the introduction of " Swinton's 
 Language Lesson'»," into the list of Canadian School Books. It is 
 *im|ile, comprehensive, and reliable ; and sliows very clearly how easily 
 the study -of grammar may be made to go hand m hand with the prac- 
 tice of Composition, the great end for which grammar ought to be 
 taught. We have at last an elementary text book which may be en- 
 trusted into the hands of the most inexperienced teacher without any 
 (ear of its boing abused. 
 
 JOHN JOHNSTON, P. S. I., South Hastings. 
 
 I have carefully examined " Swinton's Language Lessons," and am 
 convinced from what I have seen of it, and fmm what I have heardirom 
 some of my most experienced teachers, that it is by far tlie best 
 Elementary text book on the subject that has yet been placed within 
 reach of our Canadian children. The simultaneous exercises in com- 
 position are an admirable feature. I shall recommend the book for use 
 |D all the schools in my district. 
 
 J. M. PLATT, M.l)., P. S. Inspector, Picton. 
 
 I am greatly pleased wltli this little work. Our best and most ex- 
 perienced teachers teach grammar to junior classes orally, after tbf 
 same fashion. Young and inexperienced teachers can do as well with 
 " Langiiage Lessons " as the oldest and best can do without it. Fot

 . . . With its valuable aid the teacher will find it no difficult 
 task to make the study of language agreeable to even junior pupils. 1 
 esteem it so highly that I will use my influence to get it into the hand* 
 of every teacher in mj district, and, if authorized, into every school 
 likewise. 
 
 ROBERT MATHFSON, MA., H. M. High School, Walkerton. 
 
 . . . Language Lessons will assuredly prove a boon to teacheri 
 of composition. 1 find that for teuching English Grammar it is superior 
 to the usual treatises, as it treats o{ Grammar in a practical manner. 
 
 O. MOSES, P. S. I., County Haldhnaud, Caledonia. 
 I have carefully examined Swinton's Language Lessons for junior 
 cla.sses and consider it one of the best yet published, being admirably 
 adapted fur use in our public schools.

 Upwardn of three years ngn [ asked a tp-ommar sshool Ir.spector in 
 the old country to send me the uest grammar published there. Ho Im- 
 mediately sent me Mason. 
 
 A. P. KNIGHT, M.A., H.M., Kingston Collesriate Tnstltute. 
 
 Incomparuhly the best tcx' ))ook (or the senior classes of our high 
 schools that has yet been olTcrkd to the Canodian public. 
 
 J. KINO, M.A., LL.D., Principal, Caledonia, H. S. 
 
 Mason's grammar will be found a most valuable class-books fs 
 l^ecially for the instructiDii of advanced classes m English. The chapter 
 on the Analysis of ditflcult sentences is of itself sutlicient to place the 
 work far beyond any English grammar hitherto before the Canadian 
 public. 
 
 RICHARD LEWIS, H. M., Dufferin School Toronto. 
 
 As a philosophical treatise its discussion of doubtful points and iU 
 excellent methods and definitions cannot fail to give it a high rank in 
 the estimation of the best Judges of such works— the school teachers of 
 the country. It has reached a iwenty-first edition in England and 1 
 have no doubt it will meet with the same high appreciation in this 
 Province. 
 
 JOHN SHAW, H. M., H. S., Omemee. 
 . . . Mason's Orammar is Just such a book as many teachers have 
 been hoping to see introduced into our schools, its method being to 
 teach the subject by explanation, definition and abundant illustrauons 
 without stereotyped rules thereby making the study even attractive. 
 
 D. C. MacIIENRY, B.A., H. M. Cobourg Col. Institute. 
 
 It Is an excellent and reliable work. It will be well received bf 
 - tercbers and advanced pupils. 
 
 JOHN JOHNSTON, P. S. I., Belleville and South Hastlnjfs. 
 01' all the grammars that I have seen, I consider Mason's the best. 
 
 J. M0RRTS(3N, M.A.. M.D., Head Master, High School, Newmarket. 
 
 I have ordered it to be used in this school. I consider it by far ths 
 best English grammar for high school purposes that has yet apj^eared.
