1011. Acosta, Celsa. Coleccion de maderas cubanas. [Collection of Cuban woods.] 

 Revist. Agric. Com. y Trab. 3 : 55. 1920. — The Agric. Exp. Sta. of Cuba is said to have a nearly 

 complete collection of the woods (about 500) of Cuba. Thirteen of these are described in this 

 article as to specific weight and common uses. — F. M. Blodgett.

 century.] Bull. Trimest. Soc. Forest. Franche-Comte et Belfort 13: 168-170. 1920.— A study 

 of the court records of Luxeuil between 1730 and 1760 indicates that forest trespasses in the 

 eighteenth century differed remarkably little from those of today. Judgments were rendered 

 in accordance with the celebrated ordinance of 1669, the severity of which was, however, con- 

 siderably tempered in actual practice. — S. T. Dana. 



1014. Anonymous. La legende de Devoluy. [The legend of Devoluy.] Rev. Eaux et 

 Forets 58: 66-68. 1920. — The canton of Devoluy has been cited by numerous authors as a 

 classic example of the disastrous results of deforestation, which they assume to have taken 

 place toward the end of the eighteenth century, at about the time of the French Revolution. 

 A careful study by M. Philippe Arbos has shown that this is not the case; that the deforesta- 

 tion of the canton (if, indeed, it was ever wooded) dates back at least to the end of the seven- 

 teenth century; and that erosion was active as far back as 1458. The canton does not appear 

 to have suffered so severely as some of its neighbors. It has decreased less in population, 

 agriculture has picked up somewhat, and the number of stock in relation to the population 

 has increased considerably. — S. T. Dana.
