We have just issued Two New Catalogs: 
NO. 210 OF TOOLS AND BENCHES. 
NO. 2 1 1 OF AUTOMOBILE SUPPLIES AND TOOLS. 
These Books contain many items of value, and copies will be sent 
to those interested. 
Since 1848 we have 
adhered to one policy 
to handle only the 
very best in quality. 
The driftwood which is brought by 
sea currents to the far northern shores 
of Greenland, where it is the only 
source of material for the sleds, boats 
and spears of the Eskimos, proves to 
come from the St. Lawrence, the coasts 
of Norway and the great north-flowing 
rivers of Siberia. 
The American Museum of Natural 
History is exhibiting a model in wax 
and glass of two inches of sea-bottom, 
magnified fifteen thousand times.
