quality and carefully selected nature of the specimens, which 
usually included flowers and fruiting branches with date 
when each was gathered. 
Dr. Macfarlane drew attention to numerous volumes 
recently received for the Library, and to an exhibit of living 
plants from the University greenhouses. 
March 6. Dr. Miller, President, in the chair. Dr. R. H. 
True, Washington, spoke on “The Manufacture of Tea in 
the United States.” He said that the long-leaved pine 
region in which Dr. Shepherd started his experimental gar- 
den about twelve years ago, near Summerville, S. C., often 
afforded the shade that seemed helpful to the tea shrub. 
The best growths had been obtained, not on sloping banks 
as in America and China, but on the flat areas resulting from 
drainage of the small ponds. Tea seeds were imported from 
China, Japan, Indo China and Assam. The best type at 
present is a cross between an Assam and Indo-Chinese 
parentage. In conveyance of those seeds, the Red Sea 
seemed always to be a critical and trying place from the 
intense heats. By the third year plants had developed suf- 
ficiently to permit of first picking, and from that time on the 
shrubs showed vigorous growth. 
He then described the successive processes through which 
green and black teas pass till they are finally prepared. As 
regards the financial success of the undertaking, great hopes 
are entertained that the supplying of high-grade teas for 
home consumption will prove a good undertaking. The 
government, Dr. True said, had secured an area of land in 
Texas where conditions were probably more favorable than 
in South Carolina, and already plants were started on this 
spot. 
Dr. Conard next gave a lantern demonstration of methods 
for illustrating details of plant tissues. By use of the micro- 
lantern an image of a small object could be projected on the 
screen and sensitized paper applied there, so as to secure the 
impression. If a velox or similar paper were used, this
