ble in regard to the crude, together with full information regarding all the possible products t o be made from it. 6. SAxPLEs-There will be an exhibit of all types of the crude petroleum produced in the United States and some from abroad, There will be a display of samples of practically all refined products from the 2 j O odd refineries in the United States, and the crude oils from which these samples have been made will also be shown. The commercial composition, chemical composition and the physical characteristics of these products will be indicated. The companies are sending 5-gallon samples of each of their products. These will be shown in attractive glass bottles properly illuminated and labeled with data of interest. The excess of samples will be used for critical scientific examinations, which will develop valuable information as to the comparative quality of the oils produced from various districts and of various origins. This will be of great commercial, economic and scientific importance. 7. HOUSINGAND SasITaTIos-Studies of the sanitation of isolated camps. Model cottages mill be shown, built with practicable conveniences, with gardens, yards and all necessary outbuildings. 8. LECTVRES-IllUstrated by v i e w and moving pictures by eminent men interested in the petroleurn industry. 9. FIRE HAZARDSand methods of preventing and fighting fires; in cooperation with the Insurance and Petroleum Con-. gresses mentioned belo\y and with the Fire Departments of the Exposition and the City of San Francisco. CONGRESSES
Three congresses of especial interest t o the petroleum men will be held during the Exposition: TO 24TH---ipril 24th will be ISSURANCEWEEK, APRIL I ~ T H “Fire Prevention Day.” INTERSATIONAL FIRE LvASTE CONGRESS, OCT. 7TH TO gTH-Specia1 studies and displays for preventing fire wastes will be made. During these Congresses special displays of equipment for fighting oil fires will be demonstrated. This will show the best practice in using high pressure and low pressure water and steam sand and chemical extinguishers, together with the special equipment used. The precautions to be taken will be demonstrated, using burning tanks of oil on iYorth Beach. THEWORLD’SPETROLELX CONGRESS,OCT. 2 5 TO~ 3 ~0 ~ ~ This meek has been reserved by the officials of the Panama-Pacific Exposition as a period for discussions and conferences on matters of interest to the men of the petroleum industry. The program has been divided as follows: Literature, Exploration, Development and Production, Transportation, Storage and Distribution, Properties and Characteristics, Refining, Utilization, Legal Rules and Regulations, Statistics. SpEc1.4~EXCURSIOKS t o the great petroleum fields of California and Oklahoma are being arranged. A DEMONSTRATION UINEhas been installed in Block KO. 6 of the Palace of Mines and Metallurgy by the ITnited States Bureau of Mines, in cooperation with various mining companies and manufacturers of machinery, powder and mine safety appliances. This, under the floor of the building, is to illustrate various methods of mining practiced by the principal metal and coal mines of the country; it gives an excellent idea of the conditions t o be found in the mines of the United States. First aid and rescue work will be a prominent feature of this exhibit.

Hcsse on the “Chemists’ Contribution to the Industrial Development of the United States-A Record of Achievement.” Reception a t the Round Table Club, tendered by the Club. FRIDAY, April 2 , Morning and Afternoon, hieetings of Divisions. Afternoon, Motor ride for visiting ladies. Visit to the S c u Orleans Water Purification plant by the ITater, Sewage and Sanitation Section. Euening, Subscription dinner, Grunewald Hotel. SATURDAY, April 3 , Excursion to the Salt Nines at Avery’s Island. (Minimum number, seventy-five persons.) feature of the meeting will be a symposium by the Industrial Division, which was originally planned for the Llontreal meetiug. A large number of papers have been promised, giving a resume of the progress of American chemistry during the his- tory of the American Chemical Society. The symposium is t o be opened by an address by A . D. Little, presenting broadly and adequately some of the vast opportunities open to the South in the Chemical Industry. It is to be closed by a public address to the people of New Orleans by Dr. Bernhard C. Hcsse on Thursday evening. Papers by such prominent men as J . 5 . F. Herreshoff, James Lewis Rice, E. T. Bedford, W.P. hlason, R. ,C.Schuepphaus, H. Walker IVallace, Franklin \V. Hohbs, R . L. Bentley, F. R . Hazard, David Wesson, G. S. Brown, IV, D. Horne, G. D. Thevenot, I\-.H . Teas, are assured. Special attention should be directed to the proposed excursion to the Salt Mines a t Avery’s Island, scheduled for Saturday, April 3. This excursion can be given only i€ seventy-five people signify their intention t o be present and procure tickets during the early part of the meeting. The excursion will take a full day, but members will return to S e w Orleans in time t o catch the evening trains for the north. The mines themselves are well worthy of a visit, being of peculiar geological formation and interesting historically. The immense chambers hollowed out in the salt some 500 feet under ground and the unusually pure quality of the salt itself have rem dered these mines famous. The trip to Avery’s Island, which is approximately 130 miles from New Orleans, carries one into the Teche country, made famous in the story of Evangeline, and through now fertile lands only recently reclaimed from the marsh by means of scientific irrigation. The mines are being worked 500 feet below the surface and the supply of salt is practically inexhaustible.
