A VISIT TO THE JARDIN DES PLANTES. 



and rapid, till at the end of ten or twelve 

 days the tree had apparently quite assumed 

 its natural or normal condition. On exa- 

 mination, however, it was found that the 

 young fruit had become injured, and had 

 remained nearly stationary in size, present- 

 ing much the appearance of the cast fruit 

 of the peach, of a lifeless texture and drab 

 colour. The tree, however, retained its fruit 

 during the season, though its growth was 

 scarcely perceptible from week to week 

 until after the middle of September, when 

 the stoning process had probably become 

 partially perfected ; after which period the 

 fruit swelled off somewhat rapidly until the 

 latter part of October, when it was checked 

 by the frost ; some few specimens became 

 slightly coloured, but all immature and 

 worthless. The tree, however, had made 

 a fair growth of wood for the season, ap- 

 pears well stocked with fruit buds, and re- 

 tained its foliage some weeks longer, and 

 in a fresher condition, than other peach 

 trees planted in the same grounds. 



I send you the foregoing facts, to be 

 made such use of as you may think proper. 

 Perhaps they may suggest a remedy for 

 the " yellows" in the peach tree — a malady 

 with which T am unacquainted, unless this 

 case has afforded an instance of it. Your 



large experience and more extensive know- 

 ledge on such subjects may be able to as- 

 certain the nature of the disease, and the 

 effect or action of the remedy applied. 



Yours, &c., T. A. S. 



Syracuse, N. Y., Dec. 6, 1847. 



[We are obliged to T. A. S. for the fore- 

 going account of his experiment. It is in- 

 teresting, as corroborating M. Gris' views 

 of the beneficial action of iron on the health 

 of diseased foliage. We have ourselves 

 repeated this season some of M. Gris' ex- 

 periments with sulphate of iron (copperas) 

 with excellent results ; and there is little 

 doubt that almost all diseases of the foliage 

 (including the " yellows" in the peach,) if 

 taken at an early stage, may be cured by 

 its use — following the proportions laid down 

 by that writer in our last volume, p. 471. 



Our correspondent administered a pretty 

 large dose of oxide of iron to his patient ; 

 though from its being kept in a small cir- 

 cle near the trunk it does not appear to 

 have produced, as yet, any bad effects. 

 The fruit was probably injured past reco- 

 very by the diseased state of the sap before 

 he made his application of iron. We shall 

 be glad to have any accounts from T. A. S. 

 or others of further experiments. Ed.] 



A VISIT TO THE JARDIN DES PLANTES AT PARIS — NO. II. 



BY S. D. PARSONS, FLUSHING, L. I. 



Warned by our failure at the previous visit 

 to obtain admission to the greenhouses and 

 conservatories of the garden, we took the 

 precaution to send a note to M. Mirbel, the 

 Professor of Culture, who politely sent us 

 a ticket of admission to every part of the 

 establishment. 



Our route now took us by the flower 



market, and numerous small shops, where 

 bouquets of varied beauty and price greet 

 the eye. Entering the garden, we first 

 visited the Orangerie, which was now most- 

 ly filled with large specimens of greenhouse 

 plants. The light was admitted only by 

 upright sashes in front, and by occasional 

 skylights in the roof. We noticed here a
