BOOK V. III. 7-iv. I 



with the vines at intervals of six feet, there is no 

 doubt that 41 vines must be assigned to the length 

 and 21 to the breadth ; these numbers multiplied 

 together make a total of 861. But if the vineyard 8 

 has to be arranged with intervals of seven feet, a row 

 will accommodate 35 heads lengthways and 18 

 breadthways ; these numbers multiplied together 

 make 630, and this, we shall say, is the number of 

 plants which must be got ready. But if the vine- 

 yard is to be planted with intervals of eight feet, a 

 row will accommodate 31 plants lengthways and 16 

 breadthways ; these numbers multiplied together 

 make 496. If the interval is to be nine feet, a row 9 

 will hold 27 plants lengthways and 14 breadthways ; 

 these numbers multiplied together make 378. With 

 intervals of ten feet, a row will hold 25 plants length- 

 ways and 13 breadthways ; these numbers multiplied 

 together make 325. So that our discussion may not 

 be infinitely prolonged, we shall carry out our plant- 

 ing by using the same proportion to suit the wider 

 spacing which any one of us prefers. Let what we 

 have said about the measurement of land and the 

 number of plants suffice. I now return to my pro- 

 posed order of subjects. 



IV. I have found that there are several kinds of Of the cui- 

 vines in the provinces ; but of those of which I have yinci^ ^iw- 

 personal knowledge those resembling small trees yards. 

 and standing by themselves on a short stock without 

 any suppport are the most highly approved. Next 

 come those which are supported by props and placed 

 each on a single frame ; these the peasants call 

 " horsed "<» vines. Next come those which are 

 fastened round canes fixed in the ground and are 

 bent into curves and circles, their firm-wood branches
