great difficulty in deciding where to go in order to make the most 

 of his time. He is embarrassed, not by want of interesting scenes 

 to visit, but by the conflicting claims of so many localities where 

 picturesque beauty and rare forms of Plants or of Fossils attract his 

 steps. In the estimation of the Naturalist, Ireland ii anything but 

 a poor country, though she may appear so in the eyes of a Roths- 

 child. Dun given was described as a place of very great interest for 

 the botanist. The streams flow from the neighbouring mountains in 

 deep glens that afford some of the best grounds for the collector of 

 rare plants ; and the student of Physical Geology here finds a field 

 open to him that includes the three great classes of rocks — 

 Igneous, Metamorphic, and Sedimentary ; while the palsentologist, 

 who visits the limestone quarries, meets with an outcrop of the 

 Chalk that is richer in organic remains than any similar deposit in 

 the country. For the archaeologist, also, there are ancient ruins to 

 explore that will well repay examination, and there still linger here 

 old legendary associations that have long since departed from places 

 less secluded. From the summit of Benbradagh there is one of 

 the finest and farthest-reaching views in the North of Ireland ; and 

 to the lover of the grand and picturesque in Nature the pleasure 

 of such a sight would amply recompense the labour incurred. 



The Sperrin Mountains form a great, irregular group, massed 

 in the centre and South- West of the County Derry, and extend into 

 Tyrone. Many of the summits are upwards of 1,500 feet high, 

 while Sawel and Dart are over 2,000 feet. Both of these were 

 visited on this occasion, the journey being made across the moun- 

 tains to Strabane. A close, but unsuccessful, search was made for 

 the "Cloudberry" (liubus chamcemorus) . This rare plant was 

 found here in 1826 by two eminent botanists. It is a species 

 confined to the higher English and Scottish mountains, and has not 

 been met with in Ireland save in this one instance. In the forty- 

 two years that have since elapsed, the " Cloudberry" has not been 

 seen in this its only Irish station, and it becomes a matter of some 

 interest to ascertain if it still exist in its old habitat, and is entitled 

 to hold its place in our Irish flora. As far as this search was con- 

 cerned, the result was negative, not only as regards the Huhus 

 chamcemorus, but also with regard to other rare species. The
