16 THE CULTURE OF THE GRAPE. 



rafters should be twelve feet long ; this will make the height 

 of the house, at the ridge-pole, or centre, on the inside, four- 

 teen feet. The sills must be secured to stone, or locust posts, 

 placed eight feet apart, and sufficiently deep in the soil to be 

 free from danger of being thrown by the frost. Place the 

 house fronting south-southeast. You may plant three sets of 

 vines, — one in the centre, and one on each side. Upon a 

 house of this description, the sun's rays will rest from morn- 

 ing until evening, and the crop will come rapidly to maturity. 

 At the time of writing the above, I had a span grapery 

 twenty-two feet wide on the inside, (see view of this house,) 

 which had four sets of vines planted in it ; at that time, it 

 was a matter of doubt with me whether or not the vines were 

 too much crowded ; since then, they have matured a fine crop 

 of grapes, and the fruit on the two inside sets of vines was 

 fully equal in quality and quantity to those where the roots 

 were in the open border, and had more room to ramble and 

 extend themselves. The present summer, these inside vines 

 have upon them a very heavy crop ; each vine having shown 

 from fifty to one hundred large and handsome bunches. 

 They will not be allowed to mature more than from six 

 bunches for the Syrian, up to twenty for the Hamburgh, 

 being only in the fourth season. When the vines are fully 

 established, the grapes will hang from the sill to the ridge- 

 pole, and present a beautiful appearance. If there is ample 

 room, I would substitute this house for the one twenty feet 

 wide, and with only three sets of vines. 



GLASS HOUSES — HOW CONSTRUCTED. 



Glass houses, for horticultural purposes, may be constructed 

 in a great variety of forms, to suit the particular circumstances 

 of the place, or ground where it is to be located. 



It is important to have as Httle obstruction to the admission 

 of light, and as little solid wood work, as is consistent with a 

 proper degree of strength in the frame and sashes which are
