REPORT FROM SIR JOHN ROSS OF BIADENS- 

 BURG, K.C.B., K.C.V.O., ROSTREVOR HOUSE, 

 CO. DOWN. 



The autumn of 1916 was unusually harsh and wet, and 

 plants failed to ripen their wood properly ; they were 

 therefore ill -prepared to resist the cold that followed. 

 Then came the winter, which in this district was severe 

 and long, when the frost lasted, with only two breaks, 

 from early in December iintil nearly the middle of April. 

 There was a short break for a few days in the beginning of 

 January and another for some two weeks — end of Feb- 

 ruary and beginning of March. But during the rest of the 

 time the thermometer stood generally from 28*^ to 31" ; 

 occasionally the mercury dropped to 21° or 22° for one 

 night only, and the lowest reading was 19° one night in 

 Easter week. There were also periods of cold icy winds, 

 and in February they continued without any change for 

 nearly ten days, thermometer at 28° or 29°. End of 

 March the first fall of snow took place, and another in 

 April with a blizzard, temperature 31°. 



Of the half-hardy plants many, of course, have been 

 destroyed ; but there are others which resisted the cold 

 very well and are iminjured. The following list, showing 

 the killed, injured, and uninjured, in the gardens of 

 Rostrevor House, may be of interest. Only those species 

 are included among the /cih'ed which had already success 

 fully stood out a winter : many of them had been out for 

 several years, and some had grown well and were quite 

 large plants. Among the i7ijic^ed, s is put after the name 

 of a plant when only slightly damaged, and 6 when badly 

 luirt.
