As a member of The Mentor Association you appreciate the value of possessing a work that has the merit of the material that makes up The Mentor Library. Each subject is complete in every detail--and you have the privilege of possessing all subsequent volumes as fast as they are issued, which in time will be the most complete, the most authoritative, and the most interesting set ever published. It is a series that you will be proud to pass on to your children and to your children’s children; and the price is so low, and the terms so easy, that you surely must take advantage of it. YOU NEED SEND NO MONEY NOW. Simply send us your name and address with the request to forward them to you. We will send the five attractive volumes, all charges paid. You can then send us only $1.00 within ten days after receipt of bill and $3.00 a month until $36.25 has been paid--or five per cent. discount for cash, should you choose. If you will send us a post card or a letter at once we will extend your subscription for one year without additional cost, to begin at the expiration of your present membership; also you will receive, without additional charge (regular price, 25c.), the new cross-reference index, which makes every subject in the library at your instant command. You Save $4.25 If You Act Promptly Several hundred sets of The Mentor Library have been sold during the past two or three weeks, and as we have but a few sets of the present edition on hand, we are making this very unusual offer. It is necessary that you write us promptly that you may take advantage of the present low prices. We urge you to act today.
