124 THE FLORAL WORLD AND GARDEN GUIDE. 



frames are required for other purposes ; if not, draw off the lights, 

 except during frosts. Herbs, tomatoes, vegetable marrows, etc., 

 must receive lull exposure to the external air, to enable them to go 

 out sturdy and strong. Prepare the frames for growiog summer 

 cucumbers, melons, and chilies. Plants requiring to be grown on 

 briskly should be shut up earh', and have a skiff with the syringe 

 before the lights are shut down for the nisht. 



JS^EW BOOKS. 



NE of the most important books relating to plants that has 

 been published for many a mouth past is the Treasury 

 of Botany, in part prepared by the late Dr. Lindley, and 

 completed and brought down to the present time by 

 Mr. Thomas Moore, the well-known curator of the 

 Chelsea Botanic Garden. The new and revised edition of this 

 work, in two compact and beautifully-printed volumes, is as genuine 

 a " treasury '' as anything of the kind in our language, and in 

 respect of fulness, comprehensiveness, accuracy, and convenience of 

 arrangement it stands alone, for in plain truth there is no other 

 such book iu the market. The matter is arranged iu dictionary 

 form, and the entries include all known orders and all known genera, 

 inclusive of cryptogamia ; one proper consequence being that in- 

 formation desired is easily found, and the information is always 

 copious enough for general purposes. lucidentally horticultural as 

 well as botanical subjects obtain attention, and the plants known to 

 commerce for their products, such as foods, spices, etc., etc., are 

 treated with a view to furnish both trader and consumer with useful 

 information. The work is illustrated with ornamental plates and 

 explanatory woodcuts, and is in every way worthy of the respectable 



house of Longmans and Co. Dr. Hartwir/s Polar World is a fine 



addition to his handsome octavo series of works on physical geography 

 and natural history. It presents in a most agreeable form an im- 

 mense body of information on arctic and antarctic exploration and 

 discovery, and recounts the histories of the races of men that inhabit 

 the polar lands, as well as the animals and plants, the mountains, 

 lakes, rivers, and scenic curiosities of those remote regions of the 

 globe. Eor the family library we have no such books as Dr. 



Hartwig's. The new illustrated paper. The Fictorial World, has 



made a grand beginning, and we wish it a great and continued 

 success. A first-class picture newspaper, at half the price hitherto 

 charged for such a work, is a bold venture that cannot fail to find 

 an appreciative public. In spirit the paper is generous and broad, 

 free from party politics, and its nevrs so carefully selected, that it 

 may safely be left on the table for the young people. Ito pictures are, 

 of course, its main attraction, and they are such as are required in a 

 publication competing with two of the most successful ventures of 



modern times. A new edition of the Rose Booh is now at the 



service of the public. It has been in great part rewritten, in order
