Fully a thousand labels will be required for the additional 
articles. By the temporary use of typewritten labels this

available. 
In conclusion, I again urge the careful consideration of 
the above requirements. I believe that no other want 
has been more often expressed by visitors than that of the

undertaken, it should be as well done as our circumstances 
permit. Respectfully submitted,

C.E. (now Rear Admiral), U. S. Navy, in 1891-92. This 
material is mostly in the form of large fragments of matrix,
