=318. School Agents.= A lady properly qualified might, we think, conduct a school agency. As there are few school agencies in New York, we suppose it must be a business that pays. The prejudice that will probably be created by the difficulties in our country, will no doubt open the way for the preparation and employment of slave State ladies as teachers in their own States, and consequently one or more agencies in the South will be needed. The terms of one of the best agencies we know of, are as follows: "To principals who have their schools registered for the purpose of obtaining scholars by making known the terms, locality, and advantages of their schools, a fee of $5 is charged; and for each yearly renewal, $2; and for the introduction of each pupil into a registered school, where the board and tuition does not amount to $120 per annum, the fee is $5. When over that amount and under $160, $7, &c. For the registration of a teacher, in advance, $2. When the situation is obtained, and the remuneration is under $1,000, three per cent. If $1,000 and over, five per cent. When desired to examine and personally assume the responsibility of selecting teachers for important positions, an additional fee of from $3 to $5 will be charged." =319. Telegraph Instruments.= A manufacturer of telegraphic instruments in Boston writes: "We do not employ women in the mechanical part of our business, but we employ them as agents to sell our instruments for medical use. They fit themselves as lecturers by studying the science, and travel about lecturing, giving instruction, selling machines, &c. A very handsome income is derived therefrom." =320. Washing Machines.= At a washing machine establishment, I was told they make a deduction of twenty per cent. to agents who sell for them; but to agents who sell for themselves and buy six or more, they make a deduction of thirty per cent.
