ra ON PLANTING ORCHARDS. 



Defection of I shall make it an object to destroy the coccus, an insect 

 which is at present damaging all our orchards. I know the 

 application of spirits of turpentine will do it, without in- 

 juring the trees ; it is by fur the most easy and expeditious 

 method for that purpose. 



I am, Sir, your obedient Servant, 



SAMUEL CURTIS. 



T-siimon'ies. Certificates from M. P. Carter, D. D. Rector of Brad- 

 well, and Mr. Thomas Fairhead, Churchwarden, confirmed, 

 that Mr. S. Curtis had planted about four thousand standard 

 fruit trees on about forty-eight acres of land, and that the 

 same were, on the 7th of April, 1808, in a thriving condition. 



SIR, 



THE certificate I sent you relative to my orchard stated 

 the number of trees to be about four thousand, but the real 

 Disease in pear number is 4620 trees. I am sorry to have occasion to notice 

 ****• to you a disease in pear trees, almost as destructive, although* 



not so frequent as that I mentioned to be produced from the 

 insect on apple trees. This upon pear trees appears as a dry 

 rotten scab, which keeps increasing until it penetrates even 

 the hard wood, and as it proceeds, surrounds the limb eu* 

 tirely. The following spring the limb dies from the diseased 

 part upwards. I have not found any insect to be concerned 

 in this disease, which frequently takes place upon the trees 

 of most luxurious growth. Its commencement seems to be 

 from the thick rind of the tree becoming spongy; it then 

 begins to crack and look scabby, the inner bark becomes 

 dark coloured, and the disease proceeds until the destruction 

 of the limb takes place. Some particular sorts of pear 

 trees are with me much more liable to this disease than 

 others: Windsor, autumn, bergamots, Catharine pears, &c. 

 I suspect the disease to arise in a great measure from the soil. 

 My new orchard is situate at Glazen Wood, near Cogge- 

 shall, in Essex. I think myself highly honoured by the in- 

 quiries of her Serene Highness the Margravine of Anspach 

 JUrcedy for concerning it. As her Highness has attended to the prun- 

 this, and that ing of fruit trees both in England and on the Continent, 

 ® f a ??P* lre * doubtless she is aware of the existing diseases in apple and 

 * Ml ,ns " pear
