 After breakfast in his private car the President will go to Forbes field where will be held the competition of the first aid to the injured teams from all parts of the country under tn auspices of the United States bureau of mines. The mine safety demonstra- tions will be held at the conclusion of the competitions. In the test of ex- Iplosives a huge gallery, or miniature coal mine, will be used. The permissible explosive equal to one-half pound or 40 per cent nitro slycerin dynamite will be first placed in the gallery. Within will be 13s pounds of fine coal dust distributed uniformly throughout with 20 pounds on a wooden bench at the mouth of the gallery. With the firing of the rermissable explosive no explosion oi coal dust is anticipated. The same ex- pertinent, however. will be repeated for the President and this time black blasting powder will be used as the explosive. An explosion of coal dust is expected to follow the firing of the black powder. Immediately after the coal dust explosion foremen miners equipped with various types of artificial breathing apparatus will enter the gallery and recover supposed victims of the death dealing gases. As the rescuers bring out the victims the first aid miners will be on hand to re- ing the use of artificial respira ton and oxygen respirative apparatus.su7'
 Birds in Mine
 A number of doves will be carried
 into the gallery immediately after the explosion. Biologists have discovered that carbon monoXide. or white damp which follows the ignition of gas in coal dust affects birds much more quickly than men. When the birds show distress it is warning to rescuers to seek safety and take meas . ures to dissipate the gas. In the tests here anti -viviectionists will have no complaint to make because the birds will be resuscitated by the use of oxygen and will suffer no i'll effects afterward At the conclusion of the mine experiments and the competitions President Taft will present medals to the victors.
 Following this a parade of 19, 927 miners leach representing one of the 19,927 men killed in coal mines of the United States in the last 20 years--will silently pass be- fore the presidential reviewing stand. Thirty thousand miners are expected to attend the meeting
