rapidity. The expert raised the level of the cooling liquid, put in new spark plugs, corrected defects in the lubricating device, adjusted the carburetor and retimed the engine which then developed as much power as it ever had.

Advice. Very frequently we hear of the owner condemning it, without having given it any care. Some expect the tractor, replacing thirty horses which would require at least a half hour each per day to keep them in condition, to work continuously without attention or repair. Yet the owner who most severely criticizes the tractor, is very likely the one who refuses to give the hired man even two hours a day to care for the machine he is operating. We are inclined to believe that there is no tractor of reputable make on the market today, which will not do satisfactory service, provided it is given an hour or two of care per day. That is, one hour out of every ten should be devoted to lubrication, adjusting and inspecting the machine. One of the most successful operators we know stops his tractor every two and a half or three hours and makes careful inspection of the tractor and the implements he is drawing. By this method, he has kept his repair bill at a minimum, and operates for long periods without any particular trouble. This may be a little extreme, but it is much better than the method pursued by the man in this case, who was unable to accomplish anything, because he did not take care of his tractor.

The Detroit Lubricator Company of Detroit, Michagan, has gone into the carburetor business. They are making a new type of carburetor called the Stewart, which, according to their literature, differs quite markedly from other carburetors on

It thus appears that there is an actual gain in feeding value by grinding and in addition. every stockman knows that grinding utilizes every particle of the grain. It reduces waste to a minimum. It increases farm efficiency and that is what the good farmer is always trying to do.

In this connection we wish to call the attention of our readers to the new illustrated literature of the O. N. P. Bowsher Company, South Bend, Indiana, describing their excellent line of feed grinders. A request on a postal card with mention of this publication will bring you a prompt reply.

THE LAST STRAW.

There is a trusty of a penitentiary in Nevada who says his name is Woodrow Wilson. He is a mechanic and drives the warden's machine, according to the Saturday Evening Post.

Recently the warden, who is ex-Governor Dickerson, Governor Oddie, and William Maxwell, a former warden, drove over into California on an official trip. They lost their number-plate and were arrested for driving in California without a license. Governor Oddie explained to the arresting officer that he was the governor and that his companions were ex-Governor Dickerson and Mr. Maxwell. The officer was satisfied.

As the trusty was cranking up, the officer asked him: "What's your name?" "Woodrow Wilson."

"Here!" shouted the officer. "You guys come

with a metering valve which moves up and down as the suction varies and regulates the volume of air and the quantity of gasoline which is admitted to the mixing chamber. This action is entirely automatic and is said to regulate the proportions of both air and gasoline with great exactness. Their new booklet describing this carburetor is just off the press and will be sent free to anyone who will write mentioning this publi

cation.

Professor F. H. King, associate in animal husbandry at the Indiana Agricultural Experiment Station, upon being asked if it paid to grind grains for feeding live stock replied as follows:

"The advisability of grinding grain for feeding purposes depends upon a number of conditions. It does not pay to grind corn for young hogs. It adds from five to ten per cent to its feeding value after hogs have reached a weight of one hundred and fifty pounds. It usually adds from five to ten per cent to the feeding value of small grains such as barley, wheat, rye, etc., to grind them. If plenty of hogs are follow

The K-W Ignition Company of Cleveland, Ohio, filed suit on January 17 against the M & M Company of Cleveland for ten thousand dollars damages and secured an injunction restraining them from offering and selling imitation springs and contact points as K-W.

It appears that the K-W Company has got into considerable trouble on account of these imitation parts which are not made right and will not work satisfactorily on the K-W Master Vibrator. Both vibrators and coils have been returned as defective in several instances and it was found in every case that they had been fitted with the imitation springs or points. Yet they were sold as genuine K-W.

Established 1827

PREVIOUS to the year 1812 carpet tacks were

made by hand. The process was a tedious one and as a result the price of tacks was high. An experienced person could make but a comparatively small number in a day.

In 1806 a youth, eighteen years of age, by the name of Thomas Blanchard, entered the tack factory of his brother, Steven Blanchard, at West Milbury, Massachusetts. Six years later he patented a machine which turned out tacks at the rate of two hundred and seventy-five per minute.

The first step in the direction of this invention was a device to count the tacks automatically as they were made. His brother laughed at this device and gave him no encouragement at all in the development of the machine to perform the entire operation.

Previous to this time, several men had attempted a tack making machine but all had given up, for their machines were not practical.

When Thomas was still very young, his father had taken him to a blacksmith shop, six miles from the farm where he saw what he thought was a wonderful smithy who could weld two pieces of iron together. The operation made a

fearful of making his tests while his father was at home and so he waited until a day when his father and mother left him alone on the farm while they made a visit some distance away. As soon as they were gone, he secured coals

from the stove in the kitchen and, with a bellows, started the fire in his forge. To his immense delight the pieces of metal soon began to glow. He had driven an iron wedge into a log near by and this was to serve as his anvil. But he was doomed to disappointment. No matter how much he heated the irons and no matter how much he pounded them, they would not stick together.

Before he was expecting it, his father came home and although he gave him somewhat of a scolding, he recognized the boy's ability and gumption and gave him this advice.

"Well, my boy, learn blacksmithing if you like, only learn it thoroughly, and never let a job leave your hands unless it is the best you can do.

Following this advice received in his early childhood, the young inventor of eighteen worked for six years on one tack making machine. In the meantime, he was working in various kinds of shops in the vicinity of Worcester, Massachusettes. In 1812 he decided that the machine was so nearly perfected that it should be put into use. Not only did his machine turn out tacks much more rapidly than a workman, but the tacks had better heads and better points.

Young Blanchard sold the patent for this ma
