FLORAL OPERATIONS FOR THE MONTH. 327 



done blooming to remain longer, or suckei-s wiil spindle up. Camellias 

 must not be allowed to become dry, or the flower-buds will drop, let 

 them be kept moist. Where there are clusters of flower-buds thin 

 them, so as to leave onlj^ one at a place. Cinerarias are liable to be 

 attacked by green fly; if they become so, place them in a frame closed, 

 and fumigate with tobacco. Pelargoniums for exhibitions next season 

 must not be forced forward, but kept stiff". Such as fill the pots with 

 roots, should be put into a size larger. About the end of the month, 

 stop the leads of longest shoots to make them throw out laterals. 

 Do not crowd the plants. (See Articles on culture of, in previous Num- 

 bers.) Calceolarias must not have much water ; shoots will often have 

 roots protruded underneath, such should be potted off". Verbenas in 

 frames must be kept near the glass, have plenty of air, and be cai'eful 

 not to over-water them. Ericas, Epacris, Azaleas, &c., require au 

 airy situation, only protect from cold east or north winds. Plants that 

 have extended as far as desirable should have the leading shoots stopped. 

 The greenhouse should be ornamented with Chinese Primroses, Cine- 

 rarias, &c. Do nut allow the surface of the soil to be crusted, or 

 covered with moss, &c., but let it occasionally be stirred ; this very 

 miich promotes the health of the plants. Pots that become green are 

 injurious, excluding air from the roots. Only have just as much fire 

 as will keep out frost, and dry up damps. 



REVIEW.

 our own Land, their history and cultivation. By George Lawson, 

 F.R.S., Edinburgh. James Hogg, Groombridge and Sons, London. 

 12mo. 108 pages. 



The contents of this very neat, handsomely got up book are interesting. 

 Introductory Observations on the family of Water Lilies, 23 pages. 

 The Royal Water Lily, Victoria Regia, 55 pages. The Great Wiiite 

 Water Lily, Nymphsea alba, 16 pages. The Common Yellow Water 

 Lily, NympJJEea lutea, 8 pages. 



The Author has given a complete history of these noble plants, as 

 well as a minute description of each, with judicious observations on their 

 successful cultivation. 



These particulars are detailed in a very pleasing and interesting 

 manner, being interspersed with many striking relative subjects. The 

 whole is very creditable to the Author, and will be interesting to every 

 reader. 



There are two coloured plates of the Royal Water Lily. 



On the Construction of Locks and Keys. By John Chubb, Assoc. 

 Inst. C. E. 12mo. 36 pages. 



This is a neat little treatise on a subject which interests all who have 

 property to protect, and to sucii we recommend its perusal. And from 

 the practical benefit ourselves have derived from Mr. Chubb's locks 

 and iron safe, we advise all who desire security for their valuables to 

 avail themselves of these unequalled articles.
