A note in the March, 1918, number of the Botanical Journal, 
the official publication of the Royal Botanic Society of London, 
states that the Council of the society has found it necessary to 
suspend the publication temporarily, on account of the cost of 
printing and paper, and other difficulties incident to the war. 
Publication will not be renewed until conditions become normal. 
We learn from Science that an institute of agricultural botany 
is to be established at the University of Cambridge. The new in- 
stitution will be organized along the lines of the noted plant 
breeding station at Svalof, Sweden, and its activities will be along 
the lines of pure and applied science, with special attention to the 
commercial aspects of plant breeding. The scientific branch, ac- 
cording to Science, will be concerned with the production of pure 
cultures of new varieties on the field-plot scale ; and the economic 
branch will deal with the growing and distribution of these varie- 
ties on a large scale. Subscriptions toward the establishment of 
the new institute amount to upwards of £30,000. The Board of 
Agriculture will provide the necessary buildings and equipment.
