excursion, wliich had been projected to Cronkley Scar, to the 

 Slate-Pencil Mill, and to Maize Beck, had to be abandoned. It 

 had been raining the greater part of the night and it went on 

 pouring, as it often does among the hills, till the afternoon, the 

 result was that the Tees rapidly began to swell, the Porce in- 

 creased in magnitude and was soon seen in all its grandeur, 

 heavy masses of turbid water filling up completely the lateral 

 depressions and tumbling from above the central rock a height 

 of seventy feet, were precipitated into the deep basin below with 

 a loud thundering noise and reverberation, the spray and vapour 

 springing up above a hundred feet from the boiling, eddying 

 abyss. The Force was acknowledged to be, under these circum- 

 stances, a cataract of great magnitude and majesty, and is per- 

 haps scarcely equalled by any in Great Britain. It is certainly 

 superior to many much praised Continental falls. Yisitors who 

 see it in its quiet summer condition and when there has been a 

 dry season, are apt to turn away with a sneer and say it was not 

 worth coming so far to see. 



The ancient Juniper forest, on the Yorkshire side of the Force, 

 is itself well worth a visit, covering as it does many acres of land ; 

 its origin was perhaps anterior to the times of the Ancient Britons. 



It is an old saying, that ' ' If it rains at two you never know 

 what it will do ;" on this occasion, however, the rain ceased be- 

 fore four, when the party drove down to Middleton-in-Teesdale, 

 and returned home by train to find that the heavy rain had not 

 fallen only in the Yale of Tees. 



The following list of Teesdale plants has been kindly given to 

 me by Mr. Howse ; it is much more copious than that in Yol. II. 

 Transactions Tyneside Field Club, but still not so exhaustive of 

 Teesdale Botany as the Catalogue Yol. II. Natural History Tran- 

 sactions Northumberland, Durham, and Ncwcastle-on-Tync. 



The names marked thus * were observed by members of the 

 Club on June 10th and 11th.
