strations were delivered to over 4,000 children and teachers 
of grades 4 B and 5 B, between October 17 and December 
12. This codperation with the Department of Education was 
organized directly through Dr. A. T. Schauffler, District 
Superintendent of Schools, with the assistance of the school 
principals, and has been warmly welcomed by officials of the 
Board of Education. Up to the present time it has not been 
extended beyond the Borough of the Bronx, although the 
experiment was made of bringing about one hundred chil- 
dren from the lower east side of Manhattan to one of the lec- 
tures; it is believed that if the system could be extended to 
Manhattan, it would be of great additional value to the city, 
and I recommend that, in case this should appear practicable 
to the Board of Education, authority be given me to provide 
the additional lectures and demonstrations which would be 
required. 
There is a continuously increasing demand by schools and 
other organizations for the services of demonstrators to ac- 
company parties both of children and adults through the 
grounds and buildings, and this has been met as far as pos- 
sible with the force at command by detailing junior assistants 
in the several departments for the purpose. The elaboration 
of this work would greatly increase the teaching value of the 
collections, though this would necessitate the employment of 
more assistance than is possible at present; it might, with 
time, go so far as to arrange to announce publicly that guides 
would be supplied to parties applying for them between cer- 
tain hours. Mr. Skinner, the foreman at the public conser- 
vatories, gives a great deal of his time to this kind of service 
and it is highly appreciated by visitors, but it is, of course, a 
draft on time which is needed for the care and oversight of 
the collections. 
Exploration 
The importance of the exploration of little known parts of 
the world for the purpose of obtaining additions to the col- 
lections of all kinds, either by members of the staff or by 
special agents acquainted with the needs of the collections,
