June. — Considerable injury was done to many plants 

 from the protracted drought which prevailed. There were 

 twenty-four dry days during the month. On one day only 

 was there much rain, viz., on the 4th, 



Late transplanted trees and shrubs suffered most severely. 

 All surface-rooting perennials have been more or less in- 

 jured. Herbaceous plants rushed suddenly into flower, 

 and went past in an incredibly short time. Many of 

 them became scorched up in a manner which I have never 

 previously observed. Annuals of various kinds do not 

 appear to have suffered at all, and the same may be said of 

 Pelargoniums, Calceolarias, and other bedding plants. Hardy 

 deciduous trees and shrubs have been prolific of bloom. A 

 few have been finer than usual, such as the flowering Ash 

 {Fraxmus Ornns), Elder, Escallonia Phillipimia, Olearia ilici- 

 folia, and several species of New Zealand Veronicas. Eoses 

 are very dwarf, and though clean and well budded, have 

 rather a starved-like appearance. 



During the month the thermometer did not fall so low as 

 the freezing point at the garden, although in some parts of 

 Scotland it fell several degrees below it. The lowest night 

 readings were— 1st, 34°; 2nd, 38°; 3rd, 42°; 21st, 36°. 

 The lowest day temperature was 52°, on the 2nd, and the 

 highest 86°, on the 22nd. 



On the Eock Garden 432 species and varieties of plants 

 came into flower during the month, making a total of 1048 

 for the season, as against 753 at the corresponding date last 

 year. Amongst them were the following : —
