Not illustrated. 1858 edition. Excerpt: ...How many 1, 7. 1, 2, 1 and 2 equal. Another Sch. The sum of 1, 7, &c.--Tea. Yes, and you get it by adding correctly all the units. Well, read the sum.--Sch.

And nothing will so tend to this as to convince his scholars that these habits involve not only their present but especially their future welfare, and that therefore he is right in urging, or even in enforcing, them. As a reason for rubbing out the erroneous answer or working, it may be remarked that a teacher has not time to look at each operation and trace an error back through all its stages. Neither more
