translation of the Algerian Forest Code ; statistics of Federal 

 Forests in Corsica, and also a specimen Sale Clauses. As 

 contrasted with France proper, forest administration in these 

 dependencies is extensive. In addition, conditions are frequently 

 such as to render rigid working-plans impracticable. This is 

 especially the case in Tunisia, where fires and irregularity of 

 markets render systematised workings for timber production 

 extremely difficult. In this country the cork oak is the main 

 economic forest species. The times for harvesting cork are 

 regulated mainly by the period required for a given thickness 

 to be attained. The author gives interesting figures regard- 

 ing the production of cork and timber, and the prices obtained. 



The Forest Service in Tunisia has under its care several 

 valuable oases. These oases are not of the single well type, 

 but are formed by many springs which occur around the 

 perimeter of the fertile ground. The interior is usually a 

 rich date farm yielding as much as 18,739,260 lbs. of 

 dates. The chief dangers to the wells are from drifting sands 

 and erosion. Effective measures for combating these are 

 described. On the whole, costs of protection seem high, but 

 they are justified by the value of the property saved. 



Forest administration in Algeria is slightly more intensive 

 than in Tunisia. It has been found, however, that the exact 

 rules of French forests are not such as can be applied to the 

 conditions that prevail in Algeria. Modifications suggested by 

 the Jonnart Commission are proving satisfactory. 



The Algerian forests are estimated to cover about 7,000,000 

 acres, and, as a rule, only occupy land which cannot be 

 cultivated profitably. Continuous stands are formed by 

 various species of Quercus, Aleppo, and maritime pines, Cedrus 

 atlantica, Callitris quadrivalvis, and Juniperus phxnicia. Of 

 these Quercus suber and Q. mirbickii are most important. The 

 pines and cedar are only being developed. Owing to great 

 droughts the reafforestation problem is a weighty one. The 

 only successful methods seem to be the planting of small ball 

 plants, and by direct sowing. The systematic experiments for 

 the regeneration of Aleppo pine are interesting and instructive. 



In the part dealing with Corsica, British foresters will find 

 much interesting matter relating to the growth and manage- 

 ment of Corsican pine. The author states that this tree may 

 attain a height of 148 to 164 feet, with a diameter reaching
