DEPARTMENT OF THE De6mE. 271 



" The works of gazonnement have been carried on cotemporaneously with 

 the works of reboisement. They consisted in 1867 of a sowing of 600 kilo- 

 grammes of fescue grass, on 70 hectares 58 ares, and of the construction of 

 five stone barrages of 58 cubic mfetres. In 1868 they consisted in enclosing 

 the same lands. 



" But the sowing executed in 1867 is far from having given satisfactory 

 results. The Administration could supply only fescue seed, and experience 

 has shown that, on the grounds of the Alps, gazonnement can only be 

 obtained by the simultaneous employment of many kinds of seeds of 

 forage plants. 



" The five barrages have stood well, and have accomplished the purpose 

 for which they were employed, arresting the sweeping away of material 

 into the bed of V6n6on. 



" The total expense for material, transport, and labour, for the works of 

 all kinds connected with gazonnement has been 752 francs 95 centimes. 



" The surface of the p6rimfetre of the Bourg d'Oisans is too extensive for 

 the subjection of it to forest regime not to have excited certain discontents 

 among a population of which the principal industry is the rearing of cattle. 

 To meet the reiterated protests and complaints of the communes interested, 

 and to appease this opposition, the conservator, after having visited the 

 places, has proposed to maintain in the perimetre de gazonnement unenclosed 

 properties between the Gauchoirs and Villard-Eymond, and about 450 

 hectares situated in the canton of Cornillon. 



" To resume, notwithstanding the checks experienced in the works of 

 reboisement on 86 hectares and 23 ares, recorded from 1866 to 1869, there 

 are only spots of limited extent on which the regeneration sought to be 

 effected has not been accomplished. 



" As a consequence of the enclosures, the gazonnement straightway en- 

 suing, and some seeds of resinous trees, carried by the wind, have naturally 

 reclothed the soil ; and the whole surface may be considered in good 

 keeping. When the local nursery, established within the p6rimfetre, shall 

 have provided the requisite plants, it will become an easy matter, and by no 

 means costly, to complete the existing stock of trees." 



Thus are failures and success alike reported. Similar monographs are 

 given on the works executed and difficulties overcome, and results obtained 

 in the p6rimfetres of Koissard and of Cornillon in the same department, in 

 which operations were being carried on at the same time on fourteen other 

 p6rim6tres, the area of the whole comprising upwards of 7,600 hectares. 



Sect. III. — Department of the Drdme. 



The former independent State of Dauphiny included, besides what are 

 now the departments of the High Alps and the department of the Is6re, 

 the department of Dr6me. In this department there were, within the first 

 decade of these operations, seventeen p6rimfetres in which works of reboise- 

 ment or gazonnement obligatoires were being carried on. Not the least 

 important of these, but not the most important of them, was the p6rimetre 

 of Luc. 



" The p6rimetre of Luc, in the Arrondissement of Die, lies at an altitude 

 of 800 mfetres, on a mountain side, of which the general inclination is 

 to the north-west. 



" The area is 815 hectares 72 ares, of which 593 hectares 83 ares belong
