an old quarry gallery, tried the culture in it with great success. The 

 abundant crops soon went by his name, Charnbry mushrooms. 



This mode being followed by others, there are now sold in the 

 market three millions of small baskets ot mushrooms. The quarries 

 of Irry, of Grand and of Petit Montrouge, furnish the best and the 

 greatest quantity. These mushrooms are sent into the country in 

 large quantities. Mons. Noaillon distinguished himself at the late 

 Horticultural exhibition by bringing to it daily fresh baskets of very 

 fine mushrooms. 



At the late exhibition there were exhibited almost seventeen hun- 

 dred choice vegetables, and fruits and flowers of different kinds. 



METHOD OF PRESERVING APPLE TREES FROM IN- 

 JURIOUS INSECTS. 



From the Revue Horticole of Paris. 



Having devoted myself for three consecutive years to searching for 

 the causes vrhich destroy so large a number of our Elms and cider 

 apples-trees — and after having operated by a process of my own, 

 upon more than twelve hundred of these afflicted trees, of all ages 

 and sizes, I believe that I have attained results so satisfactory that 

 the Academy of Sciences should permit me to communicate the follow- 

 ing observations: (I am engaged in a more extensive memoir on this 

 subject.) 



The diseased trees in question, owe their deplorable condition to 

 the interception of the descending sap by the larva of the insect, 

 Scolytus destructor, sub armatus et multistriatus, accompanied with 

 the cossus ligniperda foi the Elms, and those of the Scolytus pruiniy 

 accompanied with the Calidiura for the. cider apple-trees. Of those 

 of the Hylesinus crenatus for the Ash-tree, Fraxinus Excelsior, &c., 

 all tending to disorganize completely the inner barks of the trees, 

 until death takes places. 



The Scolytus and Cossus attack the Elms in large towns and cities 

 where we readily believe their are causes predisposing to this injury. 

 But they also attack the Elms in the country, where they are in the 

 very best condition to flourish. This disease which has struck so 

 many Elms and which threatens almost to exterminate them from our
