THE BLAST, San Francisco, Feb . 12, 1916  This was a semi-monthly anarchist periodical existing from 1916 through 1917. The publication had roots in Emma Goldman's magazine "Mother Earth", an anarchist magazine established in New York City in 1906. 
The first issue was dated January 15, 1916, In an introductory editorial statement, The publisher noted that the provocatively named publication would be both destructive and constructive in intent: "Before a garden can bloom, the weeds must be uprooted. Nothing is therefore more important than to destroy. Nothing more necessary and difficult...To destroy the Old and the False is the most vital work. We emphasize it: to blast the bulwarks of slavery and oppression is of primal necessity. It is the beginning of really lasting construction."
The journal was originally conceived as a "revolutionary labor paper" rather than a strictly anarchist newspaper. The Blast focused on the California labor situation and provided news about national labor events and leaders of radical political movements.
Only 29 issues of The Blast were published. This is the number 5 issue (credit Wikipedia).
