 vations on the leaf development in woods, the growth relations of beeches 

 planted in light and in shade including experiments with forest trees and 

 with cultivated seedlings, pot experiments with light and shade grown beeches, 

 bud development in light and in shade, the influence of weather upon the 

 leafing-out process, and a summary of the results and conclusions.

 Serv. Bui. 87, pp. 47, pis. 5, fig. 1). — This bulletin embraces results of a pre- 

 liminary study relative to the species of eucalypts best adapted for culture in 

 Florida. The soil and climatic conditions of Florida are compared with those 

 countries in which eucalypts grow successfully, reference is made to the early 

 introduction of eucalypts into Florida, and data are given on the species now 

 growing in the State, together with a list of species suitable for various sites, 

 and suggestions relative to methods of planting most suited to Florida condi- 

 tions. The bulletin concludes with a tabulated list of eucalypts suitable to
