$1500 a Year for Life

Five shares in the great commercial rubber orchard of the Conservative Rubber Production Company should, at maturity, yield you a sure and certain income of $1500 a year. No large cash payment down is required to secure them as they can be paid for as follows: $25.00 a month for the first year; $20.00 a month for the second year; $15.00 a month for the four succeeding years; then $20.00 a month the last year-making $1500 in seven years which covers the entire cost.

One or more shares are sold at a proportional rate.

The income derived from trees during the seven-year development period should average 25% on the money invested; then $1500 a year for life. This most conservative estimate is based upon government reports of the United States and Great Britain, the most reliable sources of information in the world.

On our splendid estate of 12,000 acres in tropical Mexico, we are changing the production of crude rubber from the primitive and destructive methods hitherto employed by the natives to the most scientific and successful plan known to modern forestry, and under Anglo-Saxon supervision.

There is nothing speculative about crude rubber. It can be sold every day in the year in any market in the world at a price that has been steadily increasing for years. For a quarter of a century the world's supply has been spoken for months before it reached the civilized market. The price has doubled in a decade, and the question of future supply is of vast moment and can only be solved by the scientific cultivation of the rubber tree.

We are now engaged in this new and immensely profitable industry on a large scale, and the unusual opportunity is open to you to secure shares in our plantation. Each share represents an undivided interest in all our land-6000 acres of which is being planted to rubber, and what has already been accomplished assures the success of the enterprise.

Every possible safeguard surrounds the investor. These safeguards are embodied in the contracts which provide that you are to pay no taxes, no salaries, no fines or assessments, and payments will be suspended for three months without prejudice and may be made up at any time during the seven years.

Our literature gives conclusive facts, logical figures, and definite reference as to our integrity and responsibility, and proves that our proposition is bona fide, safe and enormously profitable. Such an investment insures the absolute safety of your future and comfort in old age. Our booklet Money Making Opportunities of Mexico" proves that our statements are absolutely correct. The Company is divided into only 6,000 shares which are being rapidly taken-over 900 people having already become associated with us.

Write to us and we will furnish you with facts that will put you in close touch with every detail of our plan.
Our iterature is Sent Free, and every request for it will receive immediate attention. Write for it to-day.

YOU will get the TECHNICAL WORLD MAGAZINE every month

for a full year-12 big, handsome, and interesting magazines. It will be the best investment you ever made of $1.50-it will bring you the best magazine you have ever read-a magazine which will interest and instruct every member of your family, every month-12 magazines, each with 112 pages of reading matter making a total of 1920 pages for $1.50 or 13 PAGES FOR ONE CENT.

The TECHNICAL WORLD MAGAZINE has correspondents in every important city in the world who are constantly gathering the latest news that you want to know and getting wonderful photographs that bring you close to the scenes they describe and make you actually see them.

During the coming year we shall print all that is new, important, and interesting concerning Air Ships, Automobiles, the New Navy, Forestry, Irrigation, Astronomy, Agriculture, Geology, Electricity, Engineering, and hundreds of other subjects too numerous to mention. We shall describe how things are made-ordinary, everyday things and the rare and wonderful things as well. We shall describe the romances and dramas of the commercial world, so little known to the average reader.

We cannot announce beforehand what these articles will be, because the events have not occurred nor the discoveries been made, but if you will look into any recent number of the TECHNICAL WORLD MAGAZINE, you can see what they will be like except that we shall make each number better than the one which preceded it.

Then we shall have a good live story-fiction-every month, some poetry, biography, stories of travel, etc., and finally we shall give some space to strange things which happen the world over-freaks of nature, wrecks and accidents which have a bearing upon our progress in knowledge of natural law.

No other periodical in the world has attempted or can attempt to cover the field as well as the TECHNICAL WORLD MAGAZINE

OVER HIS FELLOWS looms the man who has a specialized education. There is more opportunity for the Technical man today than for workers in any other line of industry. There are not enough Technical schools to supply the demand for trained Electricians, Engineers, Architects, Draftsmen, etc. Turn to the "Help Wanted" columns of any daily newspaper and compare the number of clerks, cashiers, book-keepers, stenographers, etc., looking for work with the large number of employers seeking to engage men having technical training.
