Xiv INTRODUCTION. 



Germans, built on its -nestem bank. It is tidal for about two miles above 

 its confluence with the Notter. The Notter on its eastern bank receives 

 the drainai,'e of the country lying west of the high road between Callington 

 and Altamun. After its junction with the Tidy it flows for more than a 

 mile in a south-easterly direction, till, curving suddenly round the pro- 

 montory of Erth, it runs north-east until it is lost in the Tamar, about 

 three miles below. Between St. Germans and this point it has several 

 tidal inlets on each side, receiving by a stream passing into one of them 

 on the right, the drainage of the country between St. Germans Beacon 

 and Sheviock village ; and by another on the left, most of that of St. 

 Stephens parish. The Notter is tidal for six and a half miles above its 

 confluence with the Tamar. 



The Tamar rises at Wooley Barrows, five miles south of Hartland, in 

 the north of Devon, and after a course of fifty-nine miles flows into 

 Plymouth Sound by Mount Edgcumbe. It is tidal for no less than seven- 

 teen and a half miles, and but little more than this portion of it comes 

 within our boundary line. Its course is very winding, especially in the 

 neighbourhood of Calstock and Pentillie. The first tributary of the 

 Tamar below the Weir Head, on its right bank and Cornwall side, is an 

 insignificant stream running down Danescombe ; a mile further south a 

 more considerable one brings the principal diainage of the country lying 

 between Kingston Down, Callington, and St. Dominick ; a couple of 

 miles further down a brook brings the waters of the tract lying east of 

 the turnpike road from Penters Cross to Viverdon Down. Between two 

 and three miles further south another comes down by Landulph, with a 

 wide outlet, up which the tide ascends to Kingsmill, between one and two 

 miles from the river. It drains the country between Carkeel and Botus 

 Fleming, east of the Saltash and Callington turnpike road. Rather more 

 tlian a mile below stands the ancient town of Saltash, a little south of 

 which the Tamar receives the Notter, from which point the united watei-s 

 are kjiown as the Hamoaze. They receive no more streams of any size, 

 though a few rills run down into the two large tidal inlets named respec- 

 tively 3Iillbrook and St. Johns " Lakes." 



The Tamar on its left and Devon bank has but few tributary streams, 

 and those unimportant, unless the very large affluent, the Tavy, be con- 

 sidered in the light of one. From the Weir Head to the confluence of 

 the two rivers the intervening tract is in no place more than four miles 

 across, and in some considerably less, consequently the drainage from it 

 is very inconsiderable. Below the mouth of the Tavy there are also few 

 tributaries. A stream conies down by Tamerton Foliot, with the di'ainage 

 of this parish and part of that of St. Budeaux, and is met by the tide 

 just below Tamerton village. Thence to the mouth of the Tamar are 

 only a few insignificant streams ; one of them by Weston Mills, another 

 by Keyham.
