OCTOBER. 



The month of October was on the whole favourable. 

 The first frost this season took place on the 18th of the 

 month, when the glass registered 32°. The thermometer was 

 at or below the freezing point on eight occasions, indicating 

 collectively 20° of frost for the month. The lowest readings 

 were on the 18th, 32°; 23rd, 32°; 25th, 27°; 29th, 26°; 

 30th, 29° ; and 31st, 26°. 



The lowest day reading was 45°, on the 29th, and the 

 highest 71°, on the 5th. Dalilias and other tender plants 

 were destroyed by frost on the 23rd. Deciduous trees and 

 shrubs were late in shedding their leaves. Autumn tints 

 were most conspicuous on Scarlet and Hungarian Oaks, 

 Tulip-tree, Beech; Favia fiava, Amclayichicr vulgaris, Azalea 

 pontica, and Ampelopsis tricuspidata. Amongst fruit- 

 bearing trees or shrubs the best set are Hollies, Cotoneasters, 

 and Gaultherias. Hardy Ehododendrons and Azaleas are 

 fairly well set with flower-buds. 



On the rock-garden 13 species came into flower during 

 October, as against 23 from October 1890. Amongst those 

 which flowered were : — Crocus asturicus, C. Salzmannii, 

 Erica ciliaris, Gcntiana Kurroo, Gynerium argentcum, Helle- 

 horus altifolius, Knipliojia SaiLndcrsii, Oxalis lohata, Saxifraga 

 Fortunei. The total number which have flowered since 

 January 1st is 1210 ; during the same period last year 1154 

 had flowered.
