In Switzerland, in 1861, a committee of the Swiss Foresters' Society 

 was charged to take up this subject, but after thirteen reports the com- 

 mittee was dissolved for lack of interest and only personal endeavor 

 here and there remained. 



A curious move on the part of American enthusiasts in helping the 

 movement is worth relating. After the terrible floods in 1868, the 

 Swiss consuls in San Francisco and Washington appealed to the people 

 of California and to the U. S. Department of Agriculture for tree seed, 

 since "planting of forests is the only means of combating floods." The 

 California contribution amounted to $600 worth, mostly Pinus insiguis 

 and Sequoia gigantca, but no results are on record. A park specimen 

 of Sequoia from Canton Vaud is, however, pictured as a frontispiece, 

 the magnificent dimensions of the 53-year-old tree being 92 feet in 

 height and nearly 6 feet in diameter. 



In spite of the apparent apathy on the question, private endeavor has 

 established here and there small plantations, and Badoux himself 

 planted some 500 trees of the above-mentioned conifers and poplars. 

 Especially white pine has become a regular market article. For 

 matches it "has beaten all the indigenous species" and is better paid : 

 cases are cited of 60 and 75 cents a cubic foot for special material. 

 The experience with Douglas fir, as well as Japanese larch and red oak. 

 although only 30 to 40 years old, is equally encouraging as regards 

 rapidity of growth. 



An incidental reference to the celebrated acclimation work of \ il- 

 morin at Barres is significant, since there in some cases, notably with 

 Riga pine, the second generation from seed collected at the place shows 

 itself superior in every respect to the indigenous Mora.

The well-known Pczica imllkommii had at- 

 tacked a larch plantation, now of polewood size, near T<ake Ccneva. 

 The main general attack took place about 1890, and hardly 10 per cent 

 of the trees remained immune. After a thinning in 1891. the stand had 

 a pitiable aspect and no forester would have believed in its revival, 

 r.ut the thinning had a remarkable effect: Most of the trees recovered.
