Did any one ever stop to consider how much the world owes to those who invent little things ? What is so nice as a ruler on one's desk ? But the old round ruler was always rolling when it should be at rest. Then came the round roller with an octagonal outline, which would rest - sometimes-on a sloping surface, but most penmen have had to learn to make lines as straight as possible without waiting to find the ruler. Thanks to Lord & Thomas, advertising agents of Chicago, we have now on our table a ruler which will not roll in any unruly manner, and it is combined with a paper weight, check cutter, and an inch measure. Whatever others may think, it is at least very welcome to our desk.
