exceed that height, care must be taken to top them down to that mea- 

 sure during the summer. 



To succeed well in grafting, only such species should be joined, as 

 are analogous in their fruit and the texture of their wood. Those 

 kinds that bear thick strong stems will never thrive on stocks of frail 

 and slender branches; but those varieties that have long delicate 

 stems will become more vigorous and productive if grafted on those 

 having a coarser, stronger sort of wood. But the white kind should 

 not be crossed with the red ; the grape only leses by it, if intended for 

 wine ; at least the red grape does. 



There are many species that are ameliorated by grafting, made to 

 bear choicer fruit and also in greater quantity. And all kinds that 

 will not thrive in the soil, by being inserted into roots that do succeed 

 in it, flourish without difficulty. 



Calm clear weather is the only time for grafting. If a heavy rain 

 takes place afler it, there are many chances against its ultimate 

 success. Then the superabundant moisture makes the sap watery, 

 and too thin to cement and agglutinate the scion to its new root. As 

 soon as the grafts do take they must be freed from the weeds. The 

 topping of the shoot also, should not be forgotten.
