The photographs document the process of transforming animal bones into glue, fertilizer and other products from start to finish: the arrival of steamships from South America, each carrying 5,000 tons of animal bones; the unloading of the bones from the ships and transport to the factory; the extraction of oil and grease from the bones in huge pressure tanks to produce glue; the subsequent pulverization of the bones for fertilizers, bone meal, sulfuric acid and other by-products.

There are several photographs of the factories of this prominent chemical company which was founded in Chester, Pennsylvania in 1817 and by 1927 had factories in Philadelphia and Baltimore. The electric shovels, -cranes, and -rail rail cars pictured in this album are examples of novel applications of electricity at the time when it was replacing steam for industrial power and transportation.
