From the 4th of October 1880 till the 11th of April 1881 there 

 were 134 frosty nights, giving a total of 1325° of frost. 



The long continued frost has been very disastrous to vegetation. 

 Laurels are nearly all killed to the ground. Arancaria imhricata, 

 Taxodium sempervirens, Wellingtonia gigantea much injured. Gar- 

 rya elUptica killed. Cedrtis Deodara is much injured, and in some 

 instances killed. Cotoneaster microphylla, Glcmatis Jackrnannl, 

 Lonicera hrachypoda aurea retieidata, killed to the ground. Com- 

 mon Ivy has lost the most of its fohage. Privet, English Yews 

 and Rhododendron ponticum in some situations are much injured. 

 Pampas Grass killed. Standard Eoses killed. Dwarf Roses killed 

 to the ground. 



The stems of some of the Portugal Laurels, from 4 to 6 inches in 

 diameter, were split from toj) to bottom, and I observed branches of 

 Oak and Ash trees in the park, about 6 to 8 inches in diameter, 

 also split with the intense frost. 



Vegetables suffered very much. Autumn planted Cabbages were 

 all kOled. Broccoli, Brussels Sprouts, Green Kale, and Savoys were 

 also killed. Celery much injured. 



Peaches, iSTectarines, Apricots, Plums, and other fruit trees on 

 the open Avail, have escaped A\-ithout injury. This is no doubt 

 OAving to the young Avood being in a thoroughly ripened state. They 

 are noAv full of blossom, and promise an abundant crop.
