Typically, each steamship company issued their own bill of lading, sometimes modified for by conditions or customs at the port of destination. Many bear illustrations of the steamships in the left hand margin. Bill of ladings are great historical documents showing what is being shipped. If your interest trends to financial ephemera (as mine does) or transportation ephemera, these are a great collectible area to consider.
In 1843 the first modern version of baking powder was discovered and manufactured by Alfred Bird, a British chemist. In 1846, Justus Von Liebig in Germany experiments with yeast made from sodium bicarbonate and hydrochloric acid with explosive results. In 1885, Eben Horsford and George Wilson manufacture chemicals which eventually became the Rumford Chemical Works. Horsford formulated and patented Rumford Baking Powder, the first calcium phopshate baking powder. In 1889, William Wright and chemist George Rew developed a double-action baking powder marketed under the name Calumet Baking Powder. Below find some examples of baking powder billheads.
