appear to have much of a future. The fine quality of timber at the Vuardaz bridge 

 makes it a prize for the lumberman; yet on the moist soils there seems to be a tendency 

 to early decay. The fir perhaps is a more rapid grower, and notwithstanding that its 

 wood is less sought after in the region, it is a valuable species because it is easy to re- 

 generate. The Scotch pine, introduced artificially, when found in the P6ray Canton 

 in mixture with scattering larch, seems well suited to the situation; but the stock which 

 has come in naturally, often very defective, has suffered a great deal from caterpillars 

 and the wood has httle value. The beech is quite important in the understory, but 

 with the exception of a few poles, it is not represented in the young stands; yet, because 

 of its cultural value, it ought to have a place in the mature stands. Its Utter can alle- 

 viate the acidity of the humus produced imder the spruce and also assists the natural 

 regeneration of this latter species. The oak is at its extreme elevation and is not im- 

 portant, except in the rocky areas, where, with the maples (sycamore, etc.), it serves 

 to protect the soil. One sees a few linden, service trees, and hazel, which have some 

 value. To sum up, the importance of the species is shown by the following figures: 

 Spruce, 62 per cent; fir, 2 per cent; pine, 11 per cent; oak, 10 per cent; beech, 10 per 

 cent; miscellaneous, 5 per cent.
