On Peach Trees. 277 



my garden. The cylinder was broken, when the tree 

 grew too large for it, and from that time, every spring, 

 about two quarts of sand was thrown round the roots, 

 to fill up the interstice between the tree and the eai1:h, 

 occasioned by frost during the winter, so as to cover 

 the tender bark of the root. And by this means it has 

 been so effectually preserved, that there has never been 

 a worm in it, in any part of the tree, during its exist- 

 ence ; and this has been, generally, the case with all my 

 trees. There are, however, a few exceptions that de- 

 serve to be mentioned as proof of the real efficacy of 

 this method. I had hired a man two years ago, to re- 

 new the sand round my trees, and having shewn him 

 what to do left him. The sand was to be brou2:ht, in 

 a barrow, about 150 yards, and to save himself this 

 trouble, he threw round the trees a shovel full of loam 

 and covered it with sand, so as to deceive me, and 

 lead me to suppose my orders were complied with. — 

 But the first heavy rain that fell, washed away the loam 

 and formed a gutter on the lower side of every leaning 

 tree, so as to lay bare some of the tender parts of the 

 root ; and in every tree thus exposed there was a worm 

 in a few weeks after; and there was not a worm in any 

 other tree in my garden. To this fact there are very 

 many witnesses ; and one or two of the ti'ecs so killed, 

 are now standing; left for the purpose of shewing the 

 fact to those who may enquire concerning it. I am 

 aware that the fly is sometimes found in the body of 

 the tree ; but they are found only where the bark has 

 cracked open, so as to expose the inner tender bark, in 

 wounds recently healed and not covered, and in the 

 forks of the tree, where that bark has become exposed
