CULTIVATION. 251 



In the first place there are the leaves to be considered. 

 These form a valuable fodder, whether in the green or dry- 

 state. According to Dr. E. Wein^ the composition of hop 

 leaves is as follows : — 



Green foliage Dry loliage 



with without with without 



stalks. stalks. 



Per cent. Per ceiit. Per cent. Per cent. 



Water 66-00 68-00 10-58 11-98 



Nitrogenous matter (protein) 4-74 5-11 12-47 14-03

60 to 70 of the albumin.

60 „ 75 of the non-nitrogenous extractives. 



However, since the premature cutting of the bine, or 

 stripping the leaves therefrom, has already been mentioned 

 as injurious to the vital force of the plant, it would, from a 

 theoretical point of view, be preferable to neglect this oppor- 

 tunity of subsidiary utilisation. In such event only the 

 loppings and trimmings would come under consideration as 

 fodder, the food value of the leaves and stems after dying 

 down being naturally very small. 



Dried bine can very well be utilised as a tying material if 

 soaked for a short time in water. 



Repeated attempts have been made to work up hop bine 

 as a textile material, and it was proposed by Dr. Pott to con- 

 sider the utilisation of the bine in paper-making. Bine con- 

 tains about 9 to 15 per cent, of fibre according to age, and 

 the canvas woven therefrom greatly resembles that made 

 from hemp ; but as it is unbleachable it can only be used for 

 coloured stuffs.
