afternoon with tepid water until the buds push into 

 growth, when the syringing of them should be discon- 

 tinued : the degree of moisture necessary to produce and 

 maintain a healthy growth being obtained by distributing 

 water over the surface of the borders and pathways, 

 through a rosed water-pan. As soon as the buds have 

 enlarged a little, a night temperature of from fifty 

 to fifty-five degrees should be aimed at, fifty-five to sixty 

 degrees by day with fire-heat, rising to seventy degrees 

 with sun-heat. Raise the temperature five degrees 

 all round as soon as the buds have pushed into growth, 

 making a further increase of five degrees in the tempera- 

 ture as soon as the young leaves are fairly developed 

 and the embryo bunches show. It is most important to 

 the promotion and preserving of a free, clean, and at the 

 same time sturdy growth that the atmospheric con- 

 ditions of the vinery should not be arid, and certainly 

 not too humid, but something between the two and 

 warm, moist and buoyant withal. From this point 

 onward until the grapes are in flower, a night tem- 

 perature of sixty-five to seventy degrees should be 

 aimed at. These degrees of heat will be quite high 

 enough to insure a good set of both Black Hamburg 

 and Muscat grapes ; indeed, these and other grapes will 

 set very well in a temperature a few degrees lower than 

 those given above. The lateral shoots should be stopped 

 at one joint beyond the bunch as shown by the cross-cut 

 in Fig. 10. Two joints beyond the bunch will be none 

 too far to stop at, where the vines are planted at from 

 four to five feet apart, in which case there is more trellis 

 space for the young growths to cover without being 

 crowded. 



Setting the Grapes. While the grapes are in the interest- 

 ing stage of growth known as the flowering period, 

 a somewhat drier atmosphere should be maintained in 

 the house in order to secure a good "set." To aid in
