Busses start from the Ctiemis t r y Burlding immediately-
after luncheon. In order t o provide adequately for members wishing t o take the trips it is necessary to signify one's intention at t h e time of registration. The trips include visits to the Pillsbury Flour Mills, Washburn Crosby Flour Mills, KLopper's Coke Co., Armour Packing Plant, Ford Motor Co. (including the glass works), ArcherDaniels Unseed Oil Works, and Minnesota Mining and Mfg. Co. 1 1 : 2 0 P.M.—A special excursion train will leave for the Iron Range and Cloquet (Northwest Paper Co.), returning Friday night. Friday, September 13 T R I P TO DUI/QTH, HIBBING, AND CLOQUET—One of the most
attractive features of t h e Minneapolis meeting will be the trip to t h e Iron Range and Cloquet. Special train leaves for Duluth at 11:20 P.M., Thursday, September 12, after an evening visit t o one of the large baking establishments of t h e Twin Cities. Following breakfast a t Duluth, the party will go t o Hibbing by busses. This trip from Duluth t o Hibbing is one of the most interesting in t h e Northwest. At Hibbing a visit will be made to t h e largest open-pit mines of the world. The mining operations are carried out on an enormous scale ; in fact, several years ago the whole town of Hibbing was moved to allow for these operations. Following the visit to the mines, an invitation luncheon will be served at Hibbing. The party will then proceed by bus through a section of scenic Minnesota to Cloquet, where members of the SOCIBTY will visit the huge saw mills of the Weyerhauser interests, the Wood Conversion Plant and the plant of the Northwest Paper Co. They will b e guests of the company at dinner. After dinner the party will return to Duluth for a short sightseeing trip. The train will leave Duluth for Minneapolis at 11:00 P.M., arriving in Minneapolis Saturday morning, September 14. The cost of this trip will be $16.00, including rail and bus fares for the entire trip, luncheon and dinner, and lower berth for two nights (if upper berth, the cost will be $14.80). Reservation for this trip must b e made early.

Special Notice The Council has voted that the policy of the SOCIETY regarding attendance and participation i n its general, divisional, and regional meetings shall be a s follows: (a) Attendance a t meetings is limited to registered individuals. (b) All individuals in registering shall state whether or not they are members of the SOCIETY and, if not, whether they are chemists. (c) American chemists, non-members of the SOCTBTY, shall assist in the support of the facilities which they enjoy b y paying a higher registration fee than members. This differential at general meetings shall be $5.00 higher than t h e fee charged members; while at regional and divisional meetings i t shall be at least twice t h e regular fee adopted. They shall be furnished with a special non-member badge t o differentiate them from members of t h e SOCIETY and from foreign and non-chemist guests. The differential charged shall not apply to regularly matriculated students majoring in chemistry a t any college or university. (d) Papers b y American chemists not members of the SOCIETY shall not appear on its programs unless they be joint papers with SOCIETY members.
NOTE—Corporation members have the right t o one delegate (and only one) with full membership privileges.
Ladies' Entertainment On Monday arrangements have been made for various short auto drives around t h e boulevards and lakes terminating a t the Women's Club, where tea will be served a t 4:30 P.M.

A m m o n i a Compared with Other Refrigerants B Y W . F . SCHAPHORST 45 Academy St., Newark, N . J .
This question is often asked, " W h y is ammonia usually preferred as a refrigerant?" Engineers prefer i t in large refrigerating plants because it is more efficient a n d more economical t h a n other refrigerants. The table below tells the story in a nutshell. Approximately one pound of a m m o n i a will absorb 500 heat units. Its closest competitor is ethyl chloride, b u t 3.24 pounds of ethyl chloride a r e required to do t h e s a m e tiling t h a t 1 pound of ammonia will do. Methyl chloride is practically as good as ethyl chloride. T h e poorest of all is c a r b o n dioxide, 6.82 pounds of which are needed to do w h a t one p o u n d of ammonia will do. Y e t carbon dioxide is commonly u s e d in spite of the high pressure under which i t m u s t be operated. T h i s is because carbon dioxide has no odor, even when i t leaks. Consequently it does n o t h a r m food products or irritate human "beings. T h e following- table lists t h e common refrigerants in use a n d compares them with ammonia: REFRIGERANT Ammonia Sulfur Dioxide Isobutane Ethyl Chloride Methyl Chloride Carbon Bisulfide E t h y l Ether Propane Chloroform Carbon Tetrachloride Carbon Dioxide

Floor cushions and ottomans a r e in lacque^ared fabzrics in rich colors a n d modern designs. T b e lighting amxangement consists of lamps and indirect ceiling lighting. This Matter is interesting because of the use of the recently developed fir—e-resist£ng cellulose acetate sheeting, which i s also employed onx the lajnp shades. T h e floor is covered with, solid color linolerxun, in t h e manufacture of which American lacquers, dry coJIors, a n d pigments are used.
