THE GRAPE VINE. 29 



ON THE USE OF LIQUID MANURE. 



Liquid manure may in most cases be given to vines 

 once or twice during the summer, but I am of opinion 

 that the kind to be used is very clearly indicated. I 

 consider that guano is not good, as it may cause mildew. 

 There is nothing better, if so good, as diluted cow-dung 

 or sheep-dung. This should be given to weak vines 

 as soon as they have made enough wood to show the 

 bunch, and if they are strong it may be given to them 

 as soon as the fruit is thinned out. One or two good 

 soakings with this may be given during the advance of 

 the fruit to maturity, but not after it begins to colour. 

 The whole of the ground containing the roots of the 

 vines should be saturated with this liquid manure. 



THE LATE VINERY. 



Plate 12 shows the roof of a good late vinery at 

 an angle of 45, which may or may not be double- 

 glazed ; but for keeping late Grapes through the winter 

 I advise to double-glaze such houses. The advantages 

 are obvious : first, double-glazing prevents condensation 

 of the vapour arising from the warmer air of the 

 interior upon the glass below, and consequently upon 

 the fruit ; and secondly, the double glass maintains a 

 more even temperature, for, by a free circulation of 

 fresh air, and a little fire heat to warm the pipes G, 

 no mildew can settle upon the bunches, nor other ill 

 effects arise from long keeping. 



In this case, as in that of the early vinery, the 

 border protector, c, will be quite necessary from 

 November until March, when the glass may be removed
