Vineyard Culture. 



The supports being thus set, a mat, E, is placed 

 above them. These mats [Fig. 108], being thirty-two 

 inches wide, overlap each of the two lines of wire by 

 four inches, as they are twenty-four inches apart. The 

 mats are made of rye-straw, kept together by means of 

 four strands of twine. The straw and twine are pre- 

 served from rot by being immersed in a bath of sulphate 

 of copper [Page 158]. The length of these mats is 

 sixty-five feet, and they last about ten years. 



The rows of plants, 

 at alternate distances of 

 twenty-four and f o r t y 

 inches apart, we shall 

 have, over a surface of 

 one acre, the side of 

 which is two hundred

 yards. eight rows of plants, two 



hundred and eight feet in length. As the mats shelter 

 two rows at once, there will be required eight thousand 

 one hundred and twelve feet of matting to the acre. 



For the manufacture of these mats Dr. Jules Guyot 

 has contrived a machine [Fig. 109], which, as may be 

 seen, is but a weaver's loom, adapted to that purpose. 

 M. Guyot has yielded the right of working this ma- 

 chine to M. Dorleans, who follows this business at a 

 manufactory, situated 37, Rue du Landy, Clichy (Seine). 

 The mats manufactured there are too expensive to be 

 used in vineyards, but if manufactured on the spot, by 

 the vine-growers, they are much cheaper. M. Dor- 

 leans rents out machines for making mats, and gives all 

 the instructions necessary for that purpose, but he re-
