23. Border Screens 
The screen of trees planted some years ago along the 
northeastern boundary of the reservation, adjoining land 
which was brought into the Bronx River Parkway, was 
much thinned during the early part of the year by the cut- 
ting out of many trees, as recommended in my last annual 
report, and the landscape of the valley in this region has 
been much improved by this elimination. There remain a 
few more trees which may better be removed. ‘The border 
screen on the western margin of the reservation, along the 
New York Central and Hudson River Railroad, may also 
be thinned to advantage in a few places. 
Museums 
The general arrangement of the museum collections has 
not been changed, the series of specimens illustrating 
economic botany remaining on the first floor of the museum 
building, the collection of fossil plants on the basement 
floor, the systematic collections on the second floor, and 
the herbarium and special collections on the third floor; 
all have been materially increased by additional specimens 
and somewhat modified by substitutions. 
1. Economic Museum 
Acting on previous authorization, Dr. H. H. Rusby, 
Honorary Curator of the Economic Collections, com- 
menced a revision and cataloguing of this great series of 
vegetable raw products in the spring, and has since con- 
tinued this work during all the time at his command, with 
the help of Mr. R. S. Williams, Administrative Assistant, 
and Mr. Percy Wilson, Associate Curator. Several hun- 
dred valuable specimens hitherto held in storage have been 
incorporated into the series as the work, which is now more 
than half completed, has proceeded; the catalogue, which 
includes notes and descriptive matter, has been typewritten 
in great part and thus prepared for publication in our 
Bulletin; it is anticipated that this catalogue may be made
