SOME RECENT REVISIONS OF PLYMOUTH HISTORY. 373 
added the consideration that the deed of compensation of 1592 
accounts for every yard of the land from Sheepstor right into 
Plymouth, thereby clearly ignoring the supposition of a pre- 
existing Warleigh Leat. 
It is of course stated that the Warleigh Leat ran into the Meavy 
above the Plymouth Head Weir, and it has been urged that the 
Meavy does not run along Roborough Down at the point of 
intersection. But if it does not exactly do so, it runs parallel to 
the Plymouth Leat at a point nearer to Meavy village. The ex- 
planation would therefore be this, so as to clear up the indications 
of site in the documents referred to : When Crymes succeeded in 
establishing his rights to a water supply for his new tin mills for 
forty years, at a peppercorn rent of Is., he does not appear to have 
kept these tin mills for very long, and so he probably utilised his 
temporary water rights in favour of the Warleigh water supply. 
But this would be done by turning his water supply into the 
Meavy considerably nearer to Meavy village, and then taking it 
out again on Eoborough Down, where the Warleigh water supply 
now issues from the Plymouth Leat, near Roborough Mill, which 
would be somewhere near the highway on Crymes' former property, 
near the so-called Plymouth Head Weir; i.e. the then existing 
head weir for Plymouth on Roborough Down. And in confirma- 
tion of this conclusion we have the two facts which cannot be 
denied: 1st, the payment of Id. yearly to the lord of Sheepstor 
Manor by the lord of Warleigh Manor, because the Warleigh Leat 
could easily be cut off at the Sheepstor fountain-head by the 
cutting off of the whole Plymouth Leat; and 2nd, there is the 
further acknowledgment, which the lord of Warleigh Manor had 
to make to the Plymouth Corporation, because they could easily 
cut off his supply at Roborough Down. This was the yearly gift 
of a fat buck to the Corporation, until Warleigh was disparked, 
when the acknowledgment was commuted to a guinea yearly. And 
as regards the date of the provision recited in the title-deeds of 
Sheepstor, it is clear that the reference to Warleigh, in a document 
dating only from 1751, though it may be supposed to recite pro- 
visions of pre-existing but now lost deeds, cannot be taken as 
evidence of the existence of a Warleigh Leat before the year 1590. 
Besides which there is the direct evidence of the Cecil map of 
1592, that Drake cut through the rocks below Yannadon Down for 
a water channel, which rocks " were before thought impossible to
