OF THE BUREAU OF ETHNOLOGY. XXXV 
their antiquity, these etchings form a highly important addi- 
tion to the collections before made, especially as they are in a 
region from which no representation of that nature had been 
reported. A petroglyph of interest near Machias, Maine, not 
before known, was also copied. A valuable collection was for 
the first time obtained of birch-bark pictographs which for- 
merly were in general use and still are made by the Passama- 
quoddy and Penobscot tribes of the Abnaki in Maine, showing 
a similarity in the use of picture-writing between the members 
of the extensive Algonquian stock in the regions adjacent to 
and west of the Great Lakes and those in the northeast part of 
America and on the Atlantic coast. The correlation of the 
pictographic practice in manner and extent \ as before infer- 
entially asserted, but no satisfactory evidence of it had been 
presented until the researches of this year brought into direct 
comparison the pictography of the Ojibwa with that of the 
Micmacs and Abnaki. Col. Mallery returned to Washington 
in October. 
OFFICE WORK. 
Tue Director was frequently engaged during the year in 
examining undetermined problems pertaining to his work upon 
the classification of the Indian linguistic stocks, the scope of 
which has been explained in his former reports. It was found 
necessary to defer decision respecting some of the stocks until 
after obtaining the result of additional field-work planned for 
the ensuing year. 
Co.. Mauuery, after his field-work before mentioned, was 
engaged in study of important and novel points developed 
thereby, and in continued research and correspondence on sign 
language and pictography. 
Mr. Horrman, while assisting in the work last mentioned, 
prepared a topographic chart showing all the petroglyphs within 
the limits of the United States so far recorded by the Bureau, 
with the particulars of their workmanship, coloration, position, 
and other characteristics. 
Mr. Hensnaw was chiefly employed in a solution of prob- 
lems relating to the geographic distribution of the linguistic
