PREFACE. 



The Tenth Volume of the Magazine, will be found equal in 

 interest, to any which have preceded it. Notwithstanding the 

 great amount of information which has been written upon almost 

 every branch of gardening, there are yet numerous subjects 

 w'hich have scarcely been noticed, but which will continue to 

 receive attention in future volumes. 



The Tenth Volume will close what may be called the First 

 Series of the Magazine, For the greater facility of commencing 

 subscriptions, the next volume will begin a New Series, or the 

 Eleventh Volume of the entire work. Two title pages will be 

 given, in order that the enumeration of the volumes may be 

 continued. 



In the present volume, we have commenced the publication 

 of a series of articles on the Insects which infest trees and 

 plants, by that excellent entomologist, Dr. Harris. Two have 

 already appeared, on insects which have but recently made their 

 appearance, but which, should they be allowed to increase, will 

 be highly injurious. These papers will be continued in our next, 

 and future volumes, and will, we hope, be the means of aiding, 

 by a knowledge of their habits, in the discovery of more effec- 

 tual means for their destruction'. An article on the ripening of 

 the Pear, (p. 22,) by Mr. Walker, is deserving of attention: 

 since the introduction of the numerous varieties of this fruit, 

 which ripen from November to May, it is quite important that 

 the best mode of preserving them should be known. Mr. Tes- 

 chemacher's articles on the growth of plants in charcoal and 

 guano, are subjects which will interest every cultivator. Mr. 

 Carmichael's papers on jjruning, and a continuation of our de- 

 scriptions and engravings of pears, will be found valuable to 

 the pomologist. The Reviews and Miscellaneous Intelligence 

 in this volume, are unusually interesting.
