What To Invent BY JAY G. HOBSON BOLL WEEVIL ERADICATOR TWENTY- EIGHT years ago in the year of 1892, some little fly- like bugs flew over the Rio Grande from Some other plan or device must be Mexico and settled themselves down in forthcoming soon or within a few years the Texas cotton fields nearest the cotton growing will be impossible--and border. For several years thereafter this means a calamity. The peculiar they feeding habits of the weevil makes it difficult to reach his vital spot with poisons. The punctures the female weevil makes in the square and boll of the cotton plant to eat the tender tissues there-in and to lay eggs, kills the plant Because this tender part of the plant is covered with tougher tissues which the weevil don't eat, it is impossible to inject the poison into the pod, or flower, without spoiling the cotton at maturity. One important thing the Government learned was that the weevil drinks lots of water. Dew drops and other water on the leaves supply his aqua pure. Working with this in mind, scientists began to experiment with spraying poisons in powder form over the plants which would mix with the moistures. When the weevil drank the liquid the poison would kill them. But so far this method has failed to produce the desired result because the poison employed is not the preparation required to eradicate the pest. Some other means must be found very soon to save the cotton. The inventor who can bring forth a reasonable preparation, a plan, a device or process that will were content in raising a few million eliminate the weevil can soon enjoy children on the valued cotton plants, world- but as their flock of descendants increased faster than even they first dared to anticipate, new and larger fields of cotton became necessary to maintain them, so every year thereafter a few million children moved further North until today they are a very serious pest all over the Southern cotton growing states . wide fame and fortune. Most any of the cotton growing states would gladly pay one million dollars for a sure eradication, because many times more than this amount is lost yearly from the ravages of the weevil. To be sure, it is a tremendous achievement, but I am confident before long some American inventor will solve the problem. It appears to me the logical plan to follow is for some proper chemical, rather Under favorable conditions it is about one dozen days from egg to mature weevil. In a season, which is about three summer months, one pair of weevils can give birth over 10,000,000. They can go six months without food if necessary. The weevil is one-fourth inch long and has wings like familiar house- fly. The female weevil lays eggs in the than mechanical, as the weevils are fruit of the cotton plant. She bores a not attracted at night by bright small hole in the pod or flower the plant lights, like other insects, and they are too small to be caught in a mechanical device, unless it could embrace some preparation sufficiently enticing to draw them to it. with her nose, then reverses ends and A SUBSTITUTE FOR GASOLINE.

What a Fortune Awaits the Genius Who Gives Us a "Real" and Cheap Gasoline Substitute. Copyrighted by Jay G. Hobson, 1920 Therefore the high price of gasoline is not merely a question affecting the activities of joy riders. It is a matter of serious concern to the people." We all can recall several newspaper accounts of discoveries that were going to bring the price of gasoline down to a few cents per gallon, or drive it into oblivion altogether. But King Gasoline is still on deck, more domineering and "exclusive" than ever. No practical substitute has been found, which leaves us exactly where we were years ago, when eleven cents a gallon for gas was considered high. Comparing eleven cents then with thirty- five cents now, makes a fellow feel that we did not know when we were well off. But the present high figure is a fact, and not a theory, which brings us face to face with the importance of a gasoline substitute. Undoubtedly there is a practical substitute for Nature's power- juice. What and Where, of course, is the question, but I am confident it will be found within a few years, for anything under the sun is possible except perpetual motion, and it wouldn't surprise me to learn that that, too, had appeared. Down in Texas, where they miss oil sometimes and find gas, there has been developed a practical process of extracting gasoline from natural gas. Known as "casing- head gasoline," gasoline secured from the natural gas as it flows thru the casing or pipe. Evidently some automatic process of liquidation takes place in the gas as it travels thru the metal pipes. It appears to me feasible to construct a device that will so compress natural and artificial gas that the hydrogen or gasoline liquid contents of same can be collected and stored for use in driving automobiles. A device in the form of a powerful compressor so constructed that it will take natural gas from the well, turning it into a liquid form to be used as gasoline is used today. There are millions of automobiles used daily, depending upon gasoline for fuel. This great army of consumers would gladly buy a practical gasoline substitute, and the inventor who succeeds in discovering one that will give satisfaction in power, and cost less, will be handsomely rewarded both with fame and with fortune.

None that I know of, has succeeded and right here please let me record the importance of such a discovery. How wonderful the banishment of razor slavery will be when the liquid shave is perfected. Just imagine the joy of shaving with the ease of washing the face. Some day this great preparation will be invented which will see millions of men gladly switch from the old hoe- method of today. A special preparation that would quickly dissolve the hair and not the skin, seems to me as being the practical goal to work for. One that will be both cleansing and antiseptic will make many masculine converts shout with joy. GRAPE FRUIT GUARD. A few mornings ago I was piloted across the hotel dining room by the head waiter, and sat me down to a table where the garcon was already serving three grape fruit enthusiasts. Unfortunately I joined them as all three started to operate on their "nature squirt guns," and as I sat there patiently waiting for my half, the bombardment began! All three companions had their juice artillery pointing away from their eyes and directly toward mine. They were very harmonious with the eating tools it seemed, for each plunged after the "aquacitrus," with the same vim which sent a triple stream over my way inundating me almost entirely. Had it not been for my "specks"--my eyes surely would have been blinded After the deluge (necessity being the mother of invention), I imagined what I believe to be a practical device for every dining room; a grape fruit guard like the one shown in the illustration--a device made of glass and metal. The bottom or holder part is deprest in the center to hold the grape fruit securely. The glass is crescent shape and supported above by three metal rods. The grape fruit is placed in the metal holder and under the glass. The glass is high enough to allow a spoon to be manipulated underneath. In operation the user holds the fruit with one hand, places the spoon in the fruit under the glass, which acts as guard in preventing the juice from getting into the eyes. The grape fruit habit is a popular one. Every eating place serves them. A practical and attractive device for this purpose certainly would sell big and make lots of money for the inventor if properly handled.
