account of which is given in vol. viii. p. 40, by the Rev, M. J. 

 Berkley. It attacks the skin of the fruit ; destroys the Yitality 

 of the latter, so that there is in the part of the skin affected no 

 longer any expansion by growth, and therefore as the fruit 

 swells the skin must crack, as is the case with the berries of 

 Grapes attacked by the Oidium. The Easter Beurre and Glout 

 Morceau Pears, and the Devonshire Quarrenden Apple, were 

 particularly affected with this very destructive disease. It may 

 be advisable to sulphur the trees early in spring, and occasionally 

 in the course of the summer. For applying the sulphur in the 

 form of powder, the best instrument is one invented by M. 

 Gontier, of Paris. It consists of a common bellows, of very 

 pliable leather; and on the upper side of the tube, where it 

 should be flattened, several holes are pierced corresponding with 

 similar ones in the bottom of a cylindrical box, which is fixed on 

 that part of the tube. A flat spring, loaded with about an ounce 

 weight of iron at the one end, has its other end fixed to tlie 

 under side of the bellows. When the latter is worked, the 

 spring is thereby made to vibrate and tap against the under side 

 of the bellows near the neck of the tube ; and thus the sulphur 

 is shaken so as to pass continually through the holes, to be 

 carried with the current of air against any part of the tree. The 

 sulphur may also be applied by an engine or syringe, after being 

 thoroughly mixed with water. To do this effectually, the dry 

 flowers of sulphur must be sprinkled in the first instance with 

 a very little water, then stirred till that moisture is diffused ; by 

 repeated sprinklings and continued stirring the sulpliur will 

 become a moist paste, capable of mixing with any desired quantity 

 of water. Applied in either of these ways, before and after the 

 blossoming of trees, sulphur can do no harm, and probably may 

 act as a preventive against the attack of the above-mentioned 

 destructive fungus. 



The main part of the garden, bounded by the terrace in front 

 of the range of forcing-houses on the north side, and elsewhere 

 by walls, forms a large parallelogram about 760 feet from east to 

 west by 440 feet from north to south. This area is divided into 

 four equal portions by two walks, the direction of which is to 

 cross each other at right angles in the centre. But here there is 

 a fountain of polished marble, rising out of a circular basin, the 

 latter being 30 feet in diameter. Dwarf fruit-trees are planted 

 by the sides of the walks surrounding, and intersecting this part 

 of the garden. Those by the walk in front of the terrace on
