Publication of Conservation Literature 
Brooklyn Botanic Garden Leaflets, Series XII, No. 2 (April 
16, 1924) entitled The Conservation of Beauty, was soon ex- 
hausted and was revised and reprinted as Leaflets, Series XIII, 
No. 5-6 (June 10, 1925), in cooperation with the Torrey Botani- 
cal Club, the New York Bird and Tree Club, the American Fern 
Society, and the New York Association of Biology Teachers, all 
of whom contributed funds for the publication and distribution of 
an issue of 5,700 copies. There was a large demand for the 
Leaflet from all over the country, and one of the illustrations, 
showing quantities of Flowering Dogwood being loaded into an 
automobile, was reproduced by the monthly journal Horticulture 
(Boston), and by the Minnesota State Horticultural Society, St. 
Patil. (Gy pear.) 
Series XV, No. 11-12, of the Leaflets (November 30, 1927) 
was entitled “ What Price Christmas Greens ”’, and called attention 
to the great quantities of American Holly (ies opaca), Mountain 
Laurel (Kalmia latifolia), Ground Pine (Lycopodium com- 
planatum and L. obscurum), Black Alder or Common Winter- 
berry (/lex verticillata), and Mistletoe (Phoradendron flavescens ) 
now being collected for sale at Christmas time. The following 
suggestions were made toward a solution of the problem of con- 
serving these plants : 
1. Encouraging the growing and marketing of Christmas greens 
ona commercial scale (as a crop) by nurserymen, landowners, and 
others. 
2. The protection of these plants by rigid state laws. 
3. Public education, through schools and otherwise, of the need 
of conserving these plants, and of respect of private property 
rights in the matter of collecting such material in the open country 
at Christmas time. 
Other Leaflets on conservation topics have been the following:

XVI, No. 4. May 16, 1928.)
