190 ON PLANTING AND MANAGING 



These are the principal features of this method, 

 which, perhaps, will be more clearly understood from a 

 detailed account of the mode of putting up an erec- 

 tion of this description, and planting a vine inside of it. 



For this purpose, a hollow circular column, five feet 

 high, and three feet in diameter, may be chosen. A 

 circular erection is the best, because the sun will shine 

 all round it throughout the growing season, and also 

 because the shoots of a vine can be trained so much 

 more easily round a circular column than round one of 

 any other description having corners or angles to it. 



It must first be observed, that, as the soil or ground 

 on which erections of this description can be put, will 

 have no connexion whatever with the roots of the vines 

 that are to be enclosed within them, proper and conve- 

 nient sites may be chosen wholly irrespective of the na- 

 ture of the soil on which the erections are to be built. 

 Any situation, therefore, will do, provided it be sheltered, 

 and have an open exposure or aspect facing the course 

 of the sun. 



Assuming, then, that a proper site has been chosen 

 for the erection of a column of the above-mentioned 

 description, the following directions in building it are 

 to be observed : 



1st. Lay a course of bricks on the ground in the 

 form of a square, the sides of which shall measure four 

 feet. This is to form the base of the column, and is 

 intended to give it an architectural feature. Now, if 

 tho site be near any building or wall, or straight path, 

 then the sides of this base must be at right angles with 

 that building, or wall, &c. ; but, if none of these exist, 

 then the base must be laid with its corners pointing to 

 the four cardinal points of the horizon. The joints of 

 the brickwork are to be filled in with cement or 

 strong mortar, so as to prevent the roots of the vine 

 from penetrating through into the soil beneath.
