RAL exercises in numbers of an inductive nature, . in the estimation of sound educators, have a peculiar power in strengthening and maturing the mind. | The appreciation of mental arithmetic as a means of education has given rise to urgent demands for improved methods of teaching the science. To meet in a degree new educational wants, this manual, based upon the works of Benjamin Green- leaf, has been prepared. Its lessons recognize the normal growth of the reasoning powers. The aim throughout has been to make the subject treated attractive and interesting ; and by easy steps to ad- vance the learner by sure progress. Some pages of slate or blackboard work have been appended. ‘These may be used in supplementing the oral exercises of the text, and the same form of solu- tion be shown to apply alike to mental and written problems. In the preparation of the present edition of this book, credit is due to J. V. Jackman for testing the copy in the schoolroom and for many valuable sug- gestions. 464249 TO TEACHERS. THE extent to which the book can be dispensed with by the class, in recitation, should be determined by the nature of the lesson and the attainment of the pupil. When the book is not used, each question should be repeated by the pupil after the teacher, and the required solution should always be given promptly, and in every case should form a complete sentence. A brief form of analysis only is given in the book, | so as to allow the fullest scope for the exercise of in- genuity, judgment, and discrimination on the part of the pupil in the invention of others. No form of solution, however, should be permitted to pass, unless it is neatly expressed, and is entirely accurate. Each example can be taken as a model for many original examples to be dictated by the teacher. In no other way than by giving a multiplicity of ex- amples, can a teacher fix firmly in the minds of his pupils the principles which he is imparting. Mental and written arithmetic should always be combined. Hence the wise teacher will always fol- low up what the pupil has learned, with suitable ex- amples, illustrating the same principles, which will require the use of pencil or crayon.

Sotution. — As often as A receives $3 and B $2, they both re- ceive $3 plus $2, or $5; hence A receives 3 and B 2 of thé money. 2. If you divide $24 between A and B, by giving A $3 as often as you give B $5, how many dollars will each receive ?. 3. Divide $35 between John Wilson and Simon Edwards ; how much will each get, if John receives $4 as often as Simon receives $3 ? 4, A man has two sons, to whom he leaves $660, to the elder $7 to every $4 he leaves the younger, how much does each get ? 5. I go into partnership with Thomas Gould, and pay in $5 of capital to every $4 he pays ; how much more do I pay than he? How much less does he pay thanI?

Three men hired a pasture for $36; A put in 4 oxen, B 3 oxen, and C 5 oxen; how much should each pay ? T. John Stevens and Samuel Judkins hire a pas- ture together; John puts in 8 cows for 2 days, and Samuel 4 cows for 6 days; they pay $5. rent; how much should each pay ? SoLuTION. —3 cows for 2 days would be the same as 2 times 3 cows, or 6 cows, for 1 day ; and 4 cows for 6 days would be the same as 6 times 4 cows, or 24 cows, for 1 day; and both would put in the sum of 6 cows, and 24 cows, or 30 cows for 1 day. Hence, John pays zy or 4, of $5, which is $1, and Samuel 24, or 4, of $5, which is $4. 8. Divide 60 into two numbers which shall be to each other as 7 to 5. As38to}. As 51 to 2. 9.

A gentleman has 8 sons, to whom he gives 63 cents to celebrate the Fourth of July ; Edward, the eldest, has 2 times as much as Robert, the second, and 4 times as much as John, the youngest; how much does each receive ? SoLtutTion. — John’s share is once itself, Edward’s is 4 times John’s share, and Robert’s is $ of Edward’s, or 2 times John’s. Hence, the whole sum, or 63 cents, is seven times John’s share, and John’s share is 9 cents. 12.

Now, since 18 inches + } the length of body, = the whole length of the body, 18 inches must be 4 the length of the body; and the whole length of the body must be twice 18 inches, or 36 inches. This is $ the Jength of the fish, and the whole length must be twice 36 inches, or 72 inches. 6.
