BRIGHT ON GRAPE CULTURE. 19 



In the preparation of the soil for these pots, there is 

 an opportunity for the exercise of much scientific skill. 

 The common method is, to make a compost of old sod, 

 and a little well rotted stable manure, with the addition 

 of a small quantity of finely ground bones. The lead- 

 ing requirements oi the y'me, for the formation of roots 

 and loood, are carbonaceous loam, alkaline phosphates^ 

 silicate of potash, carbonate of soda and lime, and a 

 good proportion of nitrogenous manure. Our method 

 of making composts for vine borders, so as to combine 

 the requisite ingredients in the proper proportions, will 

 be given in another part of this work. 



Proper drainage must of course be provided in the 

 pot. Pack the soil firmly about the roots, and give 

 water moderately till the pot becomes well filled with 

 roots, then water copiously. About the middle of May 

 remove the pots to the vinery, and treat them as you 

 would any ordinary vine. Pvemember that the vine is 

 a gross feeder, and requires an abundant supply of 

 water in sunny weather. 



STOPPING THE FIRST YEAR. 



Pinch off the leader when about two feet high, and 

 stop all laterals at two joints. About the first of Sep- 

 tember withdraw water gradually, only giving sufficient 

 to keep the vine from flagging ; by so doing you will 

 have well ripened roots and canes about the first of 

 October. The pots may then be placed in a cool, dry
