578 JOURNAL OF FORESTRY 



French forest authorities, that the British Army should resow with 

 Scots pine seed the areas felled. 



"Sowing commenced in 1918, and in the spring of that year 146 

 acres were sown in the forest of Brotonne and 160 acres in the forest 

 of Rouvray. The soil generally speaking is sandy in both cases, and 

 in Brotonne there is a large admixture of flints which in places im- 

 peded the preparation of the 'pits.' The "pits' were made at the rate 

 of 2,420 per acre, and consisted of areas i foot square, which were 

 cultivated to a depth of 6 inches ; where turf existed this was thrown 

 aside. The 'pits' were made during the winter, and the sowing (in 

 Brotonne) commenced on April i and finished on the 23d of that 

 month. 



"In my opinion, the areas could have been more surely and success- 

 fully reafiforested by the planting of strong, good-sized plants that 

 could have withstood the weeds, but the French forest authorities de- 

 sired the area to be sown. As the felling operations proceeded the 

 stumps of the felled trees were barked, and then charred by burning 

 the brushwood in heaps upon them. 



"These operations were carried out at the express request of the 

 French forest officers with the object of minimizing the risk of a rapid 

 increase in the number of pine bark bettle (Hylcsinits piniperda) and 

 pine weevil (Hylobius abietis). 



"Prisoner-of-war labor was employed, and the following tasks 

 were done : 



"Barking stumps (done previous to felling) — 15 to 16 trees per man per day. 



Burning stumps — 10 to 15 stumps per man per day (including collecting brush- 

 wood, igniting and watching fires). 



Preparation of pits — 250 pits per man per day. 



Sowing — gang of 20 men did 10,000 pits per day (9 men raking, 3 men 

 stamping, 4 men sowing, and 4 men covering)."

MENSURATION, FINANCE, AND MANAGEMENT 



Although the Federal law of 1876 prescribed 

 Working Plans the elaboration of working plans for the pubhc 

 in Smitserland forests of the Swiss cantons, 12 cantons of the 

 and Blseivhere 25 are still without such plans or even an in- 

 struction for making such, while in six cantons 

 the plans made thirty and more years ago are antiquated and need 

 revision. Flury discusses at great length the guiding points for such 

 revision, and first briefly refers to the revisions which were ordered
