TWENTY-FIRST ANNUAL REPORT 103 
This improvement is a necessity that must be provided in the 
very near future. No one can give the service that should be 
given at this location without new equipment. 
Guide Book.—Although the attendance for the year 1916 
fell considerably behind that of 1915, it was rather surprising 
to find that there was a slight gain in guide book sales. The 
“Gorilla Edition,” of 20,000 copies, printed in September, 1915, 
was so far reduced that the stock cannot run through 1917, and 
arrangements have been made for a new edition, to be ready 
about the first of next June. There will be a material advance 
in the cost, and a consequent reduction in profits on the new 
issue, because of the very great advance in the price of paper. 
To protect ourselves against further advances before going to 
press, the paper stock already has been purchased. 
Souvenir Books, Postal Cards, and Miscellaneous Publica- - 
tions.—The most successful article in this group of privileges 
is the series of “Animals in Art Stamps,” which were first pub- 
lished in 1915. Before the end of the year, it was found that 
the original edition was getting low. A demand for these stamps 
and the albums had developed outside the Park, and arrange- 
ments were made for a new printing from the same plates. De- 
livery was made late in the year, and they are now being folded 
and put into envelopes. 
The stock of souvenir postal cards was almost exhausted by 
the end of the summer season, and plans have been made for a 
new issue, to be ready in the spring. It is proposed to add a 
number of new subjects and discard an equal number of the least 
attractive of the old plates. On account of the paper market, an 
order for the stock was placed as soon as the new issue was 
decided upon. 
The only new feature attempted during the year in the na- 
ture of a publication to be sold in the Park, was the “Wild Ani- 
mal Stamp Primer,” a 96-page, cloth-bound book of animal stor- 
ies for children, illustrated by 50 colored stamp pictures of ani- 
mals made from photographs taken in the park. The illustra- 
tions are in the form of stamps which the child is required to 
paste in the spaces provided in connection with the stories. On 
account of an unavoidable delay, the book was delivered rather 
late in the season, otherwise the entire edition would have been 
sold, as it proved to be very popular with children.
