proved a great source of attraction to the visitors. It comprises a splendid display of 

 hyacinths, tulips, narcissus, and forced shrubs. According to the present arrange-

Amebican Sundem-s. — Mrs. Mary Treat publishes in the American Naturalist 

 for December, 1873, a remarkable contribution to our knowledge of the seusitive- 

 ness of the leaves of the Sundew, her experiments being chiefly made on the large 

 American species, Uroserafiliformis, the leaves of which capture and kill moths 

 and butterflies two inches across. Her observations are in accordance with those 

 already recorded on English species, that the motion of the glands is excited only 

 by organic substances, or if for a very short time by mineral substances, that the 

 excitement passes off almost immediately. The most astonishing of her observa- 

 tions is, however, that when living flies are pinned at a distance of half an inch 

 from the apex of the leaf, the Uaf actually bends towards the insect until the 

 glands reach it and suck its juices. Tlie American Naturalist for January contains 

 an account of Roth's observations on the irritability of the Sundew, made nearly a 

 century ago. 



TO CORRESPONDENTS. 



Caterpillars on Geranium Leaves. — J. Mancaster. — The only way to get 

 rid of the caterpillars which do so much injury to the leaves of your geraniums, is 

 to examine the underside of the leaves occasionally, and search for the caterpillars 

 and destroy them when found. It is of necessity tedious work, but with a mode- 

 rate amount of perseverance is sure to succeed. Any leaf showing signs of injury 

 should be examined at once, for the marauder can generally be found underneath. 



C. N. Lvxmore. — The Amaiew's Greenhovse will afford all the information 

 that could be desired, on the cultivation of greenhouse and conservatory plants, 

 and the Amateur's Flou-er Oarden contains similar information on the cultivation 

 of garden flowers and bedding plants, so that it is quite unnecessary to do as you 

 suggest. The price of the first mentioned is six shillings, and of the latter five 

 shillings. 



Worms in Lawns. — J. M. — The best preparation for destroying the worms is 

 prepared as follows: Corrosive sublimate one ounce, common salt one tablespoon- 

 ful, boiling water one pint, stir till dissolved. Pour this mixture into nine gallons 

 of rain water, and with it water the lawn. The best time to use it is immediately 

 after a shower, as the worms are then near the surface, and more quickly affected 

 by the mixture. The corrosive sublimate is, as many of our readers are aware 

 poisonous. 



Interior OF Fern-house. — M. A. D., Northampton. — Pieces of rock or broken 

 bricks, formed into large rough lumps with the aid of cement and sand, and washed 

 over with a solution of Portland cement, may be employed instead of the " burrs," 

 and iu precisely the same manner. If you cannot obtain stone or bricks, you will 

 of necessity have to construct a wooden stage and grow the plants in pots. 



Clematis Montana. — Oabrielle. — This Clematis would do very -well for train- 

 ing on the wall referred to, but we should prefer Clematis Jachnanni or one of the 

 varieties of the same type, of which Star of India and Ruhro-violacea may be 

 mentioned ; strong well-established plants, which may be procured for 2s. 6d., 

 would flower this year. A clematis grown in a tub will last any number provided 

 it is properly attended to and top-dressed or repotted annually. Clematis grown in 

 pots may be planted out at any season of the year. Gymnogrammas, or as they 

 are more generally termed, gold and silver ferns, cannot be recommended for closed 

 cases. Adiantums will succeed admirably, and may be grown in pots. 



Clianthus Dampieri. — W, A. — The plants may be put in pots ten inches in 

 diameter. Repot the plants at once and they will probably flower in the course of 

 the summer. It will depend upon their size now and the progress they make when 

 shifted. 



Names or Plants. — X. — No. 3, Bur Parsley, Anthriscm vulgaris ; Hares'-ear 

 Erysimum, Erysimum, orientate ; Willow Lettuce, Lactuca saligmi. 



Ornamental-leaved Plants for Indoor Apartments. — Mrs. M. C, Tenhy. 

 —The under-mentioned are most suitable lor indoor apartments, as they can be 

 kept in good health with but little difficulty : — Aralia Steboldi, Dracana auatralis,
