any farm locomotive of twelve to fifteen horsepower I 1 can be used as a source of energy I 1 and the flywheel fly wheel of this is belted to that of the portable dynamo the two conducting wires being arranged on poles along the edges of the field at right angles to the direction the plow is to follow two trolleys travel along these wires to take the current through wires parallel to the direction of plowing to the motor on the plow these wires are kept stretched by tension carriages at the two ends and rest upon two contacts carried by the plow on an arm that also serves to lift the carriages and arrange them at the proper distance for the return of the plow the plow is double being changed for the return by tilting so that the blades of the opposite end are put to work the motor on the plow rotates a drum carrying a chain held by anchors at the two sides of the field a simple lever arrangement enabling one man to shift the anchors for successive furrows acid food in the view of dr W T english of pittsburg is our latest excess the acidulous habits of the body marking a distinct stage in civilization the consumption of acid fruits pickles and add acid drinks is increasing at an astonishing rate the production of tomatoes having multiplied ten times since 1890 while the quantity of acid drinks taken has doubled in the same period every year the tendency of the acid diet Is held to be to destroy the action of the bile and pancreatic juice by neutralizing their normal alkalinity and to lessen resistance to infection by reducing the alkalinity of the blood and other bodily fluids the effects me may jy be far reaching deranging especially the nervous system and the he heart artand and even temporarily causing intellectual confusion and incoherency of thought the largest

news two claims to success in creating gold are deemed worthy of mention on account of the boldness baldness persistence and apparent scientific basis with which they have been urged the claim of dr S H immens was first advanced in august 1896 and in july of this year it was stated that nearly 1000 worth of an alloy of gold and silver which had been produced from mexican dollars had been sold to the united states assay office the profit on such manufacture being at least leapt 3 per ounce it was predicted that the production would reach ounces within a year dr emmens affirms that his work had its origin in an investigation of nickel steel in 1892 when evidence of a new substance appeared and acting on a suggestion from mr carey leas work on the allotropic allo tropic forms of silver he made a more minute subdivision of silver than mr lea obtained and compressed this in a new apparatus of great power the result is isa a substance called ar gent aurum with greater density than silver and the appearance and properties of ordinary gold the chief source of expense in the words of dr emmons is ia the time required tor for bringing about the desired molecular C changes hang e s the second process of transmutation is claimed by mr edward C brice of Chicago whose operations seem to have been begun in new york about three years ago and to have continued with numerous victims although his chicago plant is still declared a financial success A patent was applied for last may and twice refused the application being pressed an elaborate test of the process was made by the patent office with no result except partially to recover the small percentage of gold contained in commercial antimony A mixture of ninety per cent of lime live five of hosni and five of calcium
