the sicheries. And let each, conservator report the quantity of seeds 

 required by him, and their destinations. 

 " By help of this information the Administration will be able to give 

 to the trade the necessary orders, and to provide for the direct trans- 

 mission to their destination of the seeds and plants which cannot be 

 obtained in the locality. 



" Vaeious Questions Discussed by the Agents in Addition to those 

 Submitted bt the Administration. 



" The questions discussed by the agents, in addition to the programme, 

 do not appear to present in general other than purely local interest, and 

 consequently it would be useless to reproduce the whole of them in the 

 present summary. There are, however, some of those questions, which, on 

 account of their wider interest, will be mentioned here. 

 " Opinions, &e., of the Agents. 



" The agents of the conference atCarpentras have remarked, that the method 

 oireboisement by strips and by clumps seems a desirable one to practise in cer- 

 tain regions, especially in the departments of the L'Izfere and the Hautes-Alps. 

 Clumps of larch would suit well for the high mountain pasture lands. 

 " Bemarhs, &c., of the Adininistration. 



" This method of reboisement would only be efl&cacious in so far as it 

 was practised concurrently with the works for improving pasture, 

 and it is necessary to have it kept in mind, that the law for the 

 reboisement of mountains limits its action to works of reboisement 

 properly so called. Besides this, reboisement by clumps would have 

 the effect of extending the defences to embrace very vast areas 

 during the whole period of the first growth of the new plants, and 

 during the successive periods of reboisement. 

 " The question of the mixture of different kinds of trees in the reboise- 

 ment was under discussion at the conference at Carpentras, but the discus- 

 sion elicited nothing new. 

 " Eemarks, &c. 



" There has not been obtained as yet a sufficiency of results to decide 

 this question. 

 " At Foix, an agent said he had tried the effect of sulphur upon seed- 

 beds of laburnum, of ailanthus, and of pines of Aleppo. It brought only 

 to the labvimum a sensible augmentation in vigour of vegetation. The 

 sulphur was only applied at the period of the August sap. The attention 

 of the conference was called to the operation, which might be made the 

 subject of interesting experiments. 

 " RemarTcs, &c. 



" The operation of applying sulphur, which is pretty expensive, seems 

 here to have had no other effect than to increase the power of vege- 

 tation in the plants of the seed-beds. It does not appear certain 

 that important advantages result from its use. It will not be with- 

 out use, nevertheless, to make experiments in this direction when a 

 good opportunity may present itself. 

 "A proprietor of the department of L'Arifege had proposed to the 

 Administration to grant to him land for the establishment of a central 

 place for trials, experiments, and observations, in forest, pastoral, and 

 hydrological matters, in relation to the reboisement of mountains.
