GENERAL OBSERVATIONS ON 
150 
When the crop is gathered, the border (hould be frequently 
watered till the leaves of the Vines begin to change from green 
to red and yellow refpecSively. But from that time, and during 
the winter, the border (hould be kept in a dry ftate. 
I have not at any time found it neceffary to water the leaves 
of Vines growing in the pine-ftove, as is by fome recommended, 
except fuch as have been infefted with infers. But during a 
mild rain, I have frequently let down the upper lights of the 
Hot-houfe, that the Vines at the back wall might reap the 
benefit of the fliower. 
There is yet another mode of watering the Vine-border, 
which is worthy of obfervation. 
During winter, I have frequently watered the Vine-border 
with a thick black liquor, the drainage of dunghils^; and though 
this 
s The drainage of dunghils is the very ftrength and power of the dung; for 
water, conftantly filtering through ftab!e-yard dung, certainly robs it of the mu- 
cilage and faline particles, with which it greatly abounds when newly made ; and 
efpecially fuch dung as has lain a confiderable time in the ftable, and imbibed a 
large portion of the urine of the horfes. The faline particles, contained in new- 
made dung, are increafed by its fermentation, therefore the firft extradl obtained 
from the dung, after it has undergone its fermentation, may be jufily confidered 
as the cream or efience of the manure. 
In moft farm-yards this valuable liquor is generally permitted to run to wafte, 
which is much to be regretted, and may, in reality, be deemed a public lofs.
