deners. I have found grafts of the same tree 

 upon a bon-cretien stock bring chasseray pears 

 that lasted till March, but with a rind green and 

 rough ; and others, upon a metre-John stock, 

 with a smooth and yellow skin, which were 

 rotten in November. I am apt to think, all the 

 difference between the St. Michael and the 

 ambrette pear (which has puzzled our gar- 

 deners) is only what comes from this variety of 

 the stocks ; and by this, perhaps, as well as by 

 raising from stones and kernels, most of the 

 new fruits are produced every age. So the 

 grafting a crab upon a white thorn brings the 

 lazarolli, a fruit esteemed at Rome, though 

 I do not find it worth cultivating here ; and 

 I believe the cidrato (or hermaphrodite) came 

 from budding a citron upon an orange. The 

 best peaches are raised by buds of the best 

 fruits upon stocks growing from stones of the 

 best peaches ; and so the best apples and pears, 

 from the best kinds grafted upon stocks from 

 kernels also of the best sorts, with respect to 

 the season, as well as beauty and taste. And I 

 believe so many excellent winter-pears, as have 

 come into France since forty years, may have 

 been found out by grafting summer-pears of the 

 finest taste and most water upon winter stocks. 

 The third advice is, to take the greatest care
