the flue. The back wall, on the inside, is eighteen feet high, and 

 that, as well as the sides of the house, are covered with a trellis, 

 the openings of which are six inches square. Adjoining the 

 back wall, at even distances from each other, are six holes in 

 the pavement, each two feet square ; in these are growing trees 

 in the following order : 1, a Lemon ; 2, a China Orange ; 3, a 

 Lemon ; 4, a Citron ; 5, a Seville Orange ; 6, a Lemon. They 

 were planted young, nine years since ; the border of earth in 

 which they grow extends under the pavement, and their bran- 

 ches are trained to the trellis. In the same manner, last year, 

 a Citron tree was planted against the west side, and a Lime 

 tree against the east side ; and these are trained to the trellis 

 at the two sides respectively. Besides the above eight trees, 

 there are twenty-two in tubs, seventeen of which were brought 

 from Malta by Captain George Mundy, of the Royal 

 Navy, to his father, six years ago ; they were then small, but 

 have grown finely since, and the fruits they have recently 

 produced have been excellent both for size and flavour. In 

 addition to these trees in tubs, other green-house plants in 

 pots are kept in the house in the winter season. The con- 

 servatory, of which a section and ground plan are annexed, 

 is thirty-two feet six inches long ; it is divided longitudinally 

 into three borders ; the back border is three feet eight inches 

 wide, and its level is elevated three feet above the other 

 part of the house by means of a wall which supports it. A 

 paved walk, two feet eight inches wide, is carried over the 

 border, so that only about one foot of it next the back wall 

 is exposed to view : in this border, at even distances, are 

 planted one Lime, and three Lemon trees ; the Lemons are 

 of my own working, they are nine years old from the bud,
