clematis is well suited to a trellis, so also is 

 the tropjBolutn and nasturtiun; the honey- 

 suckle to the wire or rustic archway; the 

 jasmine and climbingroses to pillars, wliere^ 

 after attaining a certain height, if allowed 

 to hang down without constraint, they 

 present a graceful and truly ornamental 

 appearance. Tlie passion-flower will climb 

 a wire trellis, and show off its graceful pen- 

 dulous habit to advantage. Ivy, bigaonias, 

 and Virginian creepers are all adapted to 

 climbing the side of a house, covering a 

 wall, or the rugged bark of a tree. Grape 

 vines being grown for the fruit more than 

 f jr ornament, are usually trained to a wall 

 out of doors, and a wire trellis in-doors. 



Both are suitable, because there is a large 

 amount of stopping and pruning to induce 

 them to bear, and the object is to give them 

 that position in which they get the greatest 

 amount of heat. 



Trailers differ from climbers inasmuch 

 as they root into the ground at every joint, 

 and are ill suited to sticks, trellis, or wall. 

 To this class belong the vegetable marrow, 

 which many are in the habit of training 

 against a wall, or of laying sticks for it 

 to run over. This ought not to be done, for 

 if allowed to run along the ground, it will 

 root at every joint and bear in far greater 

 abundance.

EED, EOSE, AND BLUE FLOWERS. 



All agree that these owe their colour to 

 the same principle, becoming bine in 

 flowe/s when the liquids are neutral, and 

 red or rose colour when they are acid. 

 This principle h.is been called by a num- 

 ber of names; Fremy and Cloez call it 

 ci/anin. It is an uncrystallizable solid, 

 analogous to extractive — soluble in water 

 and alcohol, but insoluble in ether. Alka- 

 lies give it a greenish tint. According to 

 Morot, it contains nitrogen; but according 

 to my investigation, cyanin becomes blue, 

 and not green, under the influence of alka- 

 lies, and the green colour, which is observed 

 on treating a red or blue flower with a salt 

 of alkaline reaction, depends on the fact 

 that the xanthogen, which accompanies the 

 cyanine in almost all flowers, becomes 

 yellow at the same time the cyanine be- 

 comes blue. The mixture of the blue and 

 yellow constitute the green. Cyanin is 

 also nou-nitrogenous, as Morot supposed, 

 but is identical with the substance which 



Glenard calls oenoci/anin, and which he ex- 

 tracts from wine. Certain red flowers do 

 not contain xanthogen, and they become a 

 pure blue or a beautiful violet in contact 

 with ammonia. The poppy may be cited 

 as an illustration. Cyanin exists in the 

 young shoots of plants, and is sometimes 

 accompanied with substances that are more 

 especially found in flowers. This is the 

 case with the young shoots of the Bengal 

 rose, which are coloui-ed red, are odori- 

 ferous and sweet as the flowers. The sugar 

 and rose odour disappear pari passu with 

 the cyanin in the progress of the vegetation, 

 just a3 is the case with the flowers them- 

 selves. Some plants with red or rose 

 coloured flowers contain no cyanin. This is 

 the case with the aloe, whose flowers contain 

 a colouring substance analogous with ca>-- 

 thamin, and probably identical. — Filhol, in

A PHISON MADE PLEASANT. 



Leiqh Hunt, speaking of his two-years' 

 imprisonment, says : *' I papered the walls 

 with a trellis of roses, I had the ceiling 

 coloured with clouds and sky, the barred 

 windows were screened with Venetian 

 blinds, and when my bookcases were set 

 up with their busts and flowers, and a 

 pianoforte made its appearance, perhaps 

 there was not a handsomer room on that 

 side of the water. I took a pleasure, when 

 a stranger knocked at the door, to see him 

 come in and stare about him. The surprise 



on issuing from the Borough, and passing 

 through the avenues of the jail, was dra- 

 matic. Charles Lamb declared there was 

 no other such room except in a fairy tale. 

 But I had another surprise, which was a 

 garden. There was a little yard outside, 

 railed off from another belonging to the 

 neighbouring yard. This yard I shut in 

 with green pailings, adorned it with a 

 trellis, bordered it with a thick bed of earth 

 from a nursery, and even contrived to have 

 a grass plat. The earth I filled with
