E,. arvensis cannot be confounded with any of the other British 

 species ; the trailing shoots, the leaves with shallow broad-basod 

 teeth, glaucous but not pubescent beneath, and tlie pure white 

 flowers, distinguish it at a glance from all the other Roses. 



No. 2 I have not seen, but Mr. Borrer in this country and 

 M. Des^glise in France agree in remarking that it resembles the 

 South European species 11. sempervirens. Mr. Baker says that the 

 stems are stronger than in the common form of E,. arvensis. 



WTiite-flowered trailing Rose. 



French, Rosier des Champs. German, Feld Hose. 



This pretty Rose is found in open situations, and is a trailing plant, sometimes root- 

 ing at the joints; but in hedges and among bushes it is a climber by elongation, reaching 

 to their tops and covering them with tufts of foliage and flowers ; the leaves remaining 

 on late in the season, and the fruit continuing often to the winter. Several varieties 

 of this climbing Rose are cultivated by nurserymen, who call them Double-hip Roses, 

 and use them to cover naked walls or unsightly buildings. The growth and cultivation 

 of Roses is a subject of special interest to the gardener, and every year we find, from 

 the different floral exhibitions, that great improvements are being made in the art of 

 growing perfect Roses. They will by no means grow everywhere, and as a rule require 

 a clear atmosphere and a light soil. Masses of Roses planted together, in beds 

 edged with wire so as to imitate a basket, have a very pi-etty effect, and the delicious 

 scent they emit is very grateful. Standard Roses are best on lawns or flower-beds 

 placed singly. The Monthly Rose being protected by glass in autumn, or aided by 

 artificial heat, may be continued in bloom till Christmas. A very common mode of 

 obtaining late Roses, and one of the greatest antiquity, is by cutting all the flower-shoots 

 off when the buds begin to appear, or by rubbing off all the rudiments of shoots of 

 every kiud early in the spring. A secontl croji is in consequence produced, which will 

 not be in a state to blossom before the autumn. A great number ol insects seem to 

 delight in the flowers of Roses, from the earwig to the golden-green Rose-chafer. There 

 seems to be no remedy for insects on plants in the open air so simple and effectual as 

 gathering them by hand, or removing the leaf or part of the shoot affected by them. 

 Under cover, tobacco smoke will often destroy the little aphides or "green-fly," but is 

 perfectly harmless to many other insects. The j)retty ladybird is one of the gardener's 

 best friends, as in its larva state it greedily devours the aphides, which may be seen 

 (especially in dry seasons) smothering the young shoots and buds of Roses, sucking their 

 juices, and so preventing the flowers from attaining their full development : the lace-wing 

 fly is another useful auxiliary. The beauty of the Rose is often impaired by the froth of 

 Cicada spiDiiaria (cuckoo-spit, as it is commonly called) ; but the singular transformations 

 of this little insect are an interesting entomological study. The leaf-cutter bee cairie
