SPECIAL LECTURES: On request from any high school 
teacher a member of the staff will arrange to give at the Garden 
an illustrated lecture before a class or group of students, on any 
subject related to the school course in botany, so far as illustra- 
tive material for the same is available at the Garden. 
SEMINAR AND JOURNAL CLUB: From October to May, in- 
clusive, the Garden staff holds weekly meetings for the discussion 
of scientific questions. Every second meeting is a Seminar, and 
this alternates with a Journal Club for the review of current 
botanical literature. These meetings are from 4-5 p. m. on a dav 
of the week agreed upon in advance. All teachers of botany are 
cordially welcomed to join and participate in these conferences. 
Full information will be given on request. 
LEAFLETS: The Brooklyn Botanic Garden Leaflets, issued 
weekly or bi-weekly from April to October, give timely informa- 
tion concerning flowering and other seasonal activities of plants 
in the Garden, or treat of various phases of plant life. Their aim 
is to diffuse popular but accurate information, and to create and 
stimulate a love and appreciation of plants in both children and 
adults. They are issued free, and any person who wishes may have 
his name placed on the mailing list to receive them regularly. 
Teachers who wish additional copies of any issue for class use, 
or to distribute to pupils or others, will be supplied as long as 
extra copies are available. For complete sets of preceding series 
there is a nominal charge of fifty cents plus postage. 
FURTHER INFORMATION: The director of the Garden, or the 
curator of public instruction will be glad to give any further in- 
formation concerning the Garden, and will warmly welcome any 
suggestions from teachers or others as to how its educational 
work may be made to meet more fully the needs of its co-workers 
in botanical instruction.

PLANTS NOW IN BLOOM 
Among the plants flowering at this season are the following: 
the horse-chestnut, Aesculus hippocastanum , perhaps the best 
shade tree for lawns. There are trees scattered all along the 
Flatbush Avenue border mound. A pink-flowered form is also 
flowering at this time, but there are no specimens in the Garden. 
Both the common barberry, Berberis vulgaris, and a Japanese 
species, B. Thunbergi , are flowering, there being many specimens 
along the border mounds and in the decorative shrub planting in 
the local flora valley. Among the thorns many specimens are 
flowering, notably Crataegus Crus-Galli and the English haw- 
thorne, C. Oxyancantha. The latter is widely planted and has 
become the source of more than fifty horticultural forms, many of 
them of great beauty and usefulness in the shrubbery. Along 
the local flora shaded path the common crane’s-bill and the herb- 
Robert, Geranium maculatum and G. Robertia?ium, are both
