140 CULTIVAHON OP THE GRAPE UNDEE GLASS. 



CULTIVATION OF THE GEAPE UEDEE GLASS. 



The foUowing hints are designed to aid those who are desirous 

 of growing a few vines under glass, and who propose to he in 

 this matter their own gardeners, and heing therefore without the 

 assistance of scientific cultivators, wish to avaU themselves of 

 plain, simple directions how to proceed. The writer, in preparing 

 these suggestions, has availed himself of the very admirahle little 

 treatise by Mr. WiUiam Thomson, of Dalkeith Park, Scotland, 

 making such changes as the difference in climate seemed to 

 require. 



SHAPE AND SIZE OP VINERY. 



When the object sought in the erection of a vinery is the 

 production of early Grapes, there is no form so suitable as a "lean- 

 to,"' with the roof sloping full to the south-south-east. When it is 

 desired to have late Grapes, say those ripening in August and 

 September, the span-roofed form is best and most economical, 

 and should be placed with one end to the south and the other to 

 the north, which will make the roof to slope to the east and west. 

 It is better that the house be of sufficient size to be maintained 

 easily at a uniform temperature. If it be very small, it is too 

 easily affected by the changes of weather going on without. Let 

 it be, if practicable, say height of back wall fifteen feet ; width 

 of house fifteen feetj height of front sashes two feet slk inches; 

 length forty feet, outside measurement. A house of these di- 

 mensions has a good length of rafter, which enables the vines to 

 carry a large extent of foliage, and become vigorous plants as 

 compared with those confined to a short rafter. The front sashes 

 should be in sections, and hung upon hinges at the upper edge, 

 having a curved, notched iron rod fastened on the inner side of 

 each section, so that any one or all of these sections can be opened 

 to any desired extent, when required for the purpose of ventil- 

 ation, or kept securely closed. The upper ventilators should be 

 three feet long by one foot wide, and placed in the back wall
