surface of the soil, or plunging materials, and walls 

 of the structure ; all this will maintain a faTOurable 

 and kindly humidity both night and day, and no 

 shading will be required under such circumstances. 

 Thus treated, a growth vigorous and rapid will be 

 quickly established and maintained. As to ^ a ferru- 

 ginous hue,' no such objectionable appearance will 

 ever be observed if the system I have recommended is 

 faithfully carried out. There need be no fear what- 

 ever of any depredation from insects, as such treat- 

 ment will quickly scourge them, let them be ever so 

 numerous. Respecting grape vines being introduced 

 into a pine structure, I condemn it altogether. No 

 man, under such a combination, can do entire justice 

 to either one or the other. The shade from the vine I 

 am perfectly convinced is injurious to the pines. What 

 is gained by one is loss in the other, and neither 

 very often will be of first-rate quality. I am for se- 

 parate structures, to do justice to each.'' 



Being an advocate for shade to a limited extent, 

 even to the fruiting plants, Mr. Glendinning does not 

 object to grape vines being trained up, and confined 

 to the rafters of the fruiting-house, but, on the con- 

 trary, would prefer them as a useful, ornamental, 

 and economical screen. One great evident advantage 

 arising from shading the young plants, when the day 

 proves clear, and the foliage has been moistened in 

 the morning, will be the prolongation of a damp
