 referring to many different lines of work and appearing in various 

 forms, do not bear consecutive numbers or cQUstitute a regular series, 

 and on account of limited editions not being available for distribution, 

 even to public libraries, agricultural experiment stations, or to col- 

 laborators of the Department of Agriculture, they are not classed as 

 " publications " and no announcement of their issue from the press is 

 made by the Department.
