R I V E R T R A N S P O R T A T I O N of Chlorine has received strong impetus as the result of a new barge designed and perfected by Columbia. Cradling four huge tanks in its 135 foot length, the barge transported 380 tons of Liquid Chlorine on its maiden voyage in Septem* ber from Natrium to Charleston, W . Va. Formerly, all river shipments had been limited to one^ton containers—a slow and tedious handling method in com' parison with the new barge. This is the latest of numerous improvements in the transportation of Chlorine and other chemicals introduced by Columbia. A
CHLORINE MARKETS—If you are interested in developments in the manu* facture of Chlorine and the probable part this chemical will have in the postwar period, an enlightening analysis is pre' sented in the article published in the August issue of Chemical & Metal* lurgical Engineering, page 115. Included are data on plant expansion and manufacturing methods, new and potential uses of Chlorine.
When Accuracy is a Must O n t h e horizons rim, t h e enemy maneuvers desperately to elude t h e conflict. T h e first salvos must £nd t h e i r marks t o assure decisive action. T h e range finder brings t w i n images into sharp coincidence . . . the range is worked into a formula with speed a n d course, barometric pressure, air temperature and humidity, wind deflection, powder temperature. Within seconds t h e turrets swing and the huge guns roar . . . the spotter checks the p a t t e r n of a perfect salvo, amazing in its accuracy, which initiates another great naval victory. Accuracy in t h e manufacture of many products is today accepted almost casually. But intense and c o n s t a n t effort is required t o maintain these high standards. Columbia, recognizing the problems of its customers, helps to make their task easier by furnishing chemicals which meet exacting specifications.

COLUMBIA RESEARCH—Though they have not been glamourized, the activities of Columbia's Research Lab' oratories have contributed much to the nation's war effort. Synthetic, natural and reclaimed rubber, textiles, plastics for aircraft, water purification and chem* icals for other military uses—these are but a few of the important fields in which this research has played a vital role. A.nd it will have an equally important part in serving thé world's needs when peace has been restored.

NO INHIBITORS are required in Columbia's thermosetting plastic, Allymer, to prevent polymerization while in storage. Allymer may be stored under ordinary conditions for several months without appreciable change. This sta* bility eliminates the distillation or wash' ing processes necessary for removal of inhibitors used in older monomers, and facilitates mass shipment and storage. Data and reports of extensive research on Allymer may be obtained on request.
