These thirteen articles are to be found in the annual volumes 

 of the Mitteilungen der Deutschen Dendrologischen Gesellschaft 

 and in separate reprints. 



In 1906 appeared Analyse et Contr61e des Semences Forestie- 

 res by M. A. Fron, Professor in the Forest School of Barres (Ber- 

 ger-Levrault et Cie. Paris et Nancy, 1906. 128 pages in Quarto). In 

 this treatise were included a number of the Author's results, 

 published in the transactions of the Deutsche Dendrologische 

 Gesellschaft on the weight of seeds from different collecting 

 grounds, as well as purity determinations and germination experi- 

 ments, particularly on rare American and Japanese species. 



These figures and notes, compiled from year to year, are col- 

 lected and collated in the present work. Tables are given showing 

 the weight, purity and utilization value of the various species of 

 seeds. Not only the average, but also the highest and lowest figures 

 met with during the whole period are given. In addition, the course 

 of germination is itself set forth. 



Efforts were constantly made to obtain the germination results 

 as rapidly as possible. The earlier practice of the Seed-testing 

 Institution was to issue a report on the germination of a sample
