headings is most attractive, although. It calls for a 
larger expenditure in Panama than I had contemplated

that ray desire is for heroariua specimens and that my 
measure of success is the number of specimens secured.

worth while would mean that the number of specimens 
collected and delivered would equal the money value of 
specimens as usually purchased. As an example let us asd

Then for each dollar expended, to oe profitable, the 
venture should yield five specimens. That would be at

thousand specimens a year. ^Tille twelve thousand specif^
