the Eiver Leader, and 20 feet above its bed. We are thoroughly 

 well sheltered by high plantations on all sides except the south, and 

 enclosed by hills on north-east, west, and south-west, which rise to 

 a height of about 1000 feet. There are two streams in addition to 

 the Leader, one on each side, at a distance of about 300 yards, so 

 that the place is very much subject to hoar-frosts. The soil is a 

 clayey loam on a tilly subsoil, and the ground slopes slightly to the 

 north-east. 



Loicest Headings of Thermometer in Air, and Protected, during the 

 Winter of lSm-^\. 



From the above readings of January it will be seen that there is 

 a mean of something less than a degi-ee above zero, while that of 

 the 17th is 3° lower than we ever had before. With all this, how- 

 ever, we cannot show so much injury to plants on account of their 

 being so terribly cut up the winter before, which gives us less to 

 work upon. "Wellingtonias are all but killed off. Rhododendron 

 jjonticum is so much destroyed that I am afraid most of them will 

 require to be cut down. Yews have again suffered much, both as 

 single plants and as hedges, of which we had some nice little bits, 

 but I am afraid they are now past recovery. A large number of 

 Tree Box are entirely killed, many of them having been planted 

 forty years ago, when the gardens were laid out. All the Laurels 

 on the place were killed to the ground in 1878-79, and the young 

 wood they have since made is again killed back. Clematis are all 

 killed. Eoses on walls, and the young wood of Peaches and other 

 fruit-trees, appear to be safe. Eoses, &c., in open borders are 

 killed down to the snow-line. Vegetables never were so completely 

 destroyed, the whole of them being killed excepting Leeks and 

 Parsley.
