CINCHONA OULTn'ATION. 



To initiate a discussion on Coltivationof CinchoNjV 

 and the best mode of Harvesting Bark, the Cn.Mr.MAN 

 proposed the following resolution: — "That the best 

 mode of Harvestin;; Birk is to ehave the trees every 

 six mouths, between 3 and 5J years; but that, after 

 that age, iit is unwise to shave trees, unless they 

 have not, up till then, showed signs of seeding. 



Mr. Arthdr Campbell thought that no rule could 

 be laid down as to the age at which a tree can be 

 shaved with advantage, so much depended upon the 

 growth of the tree, consequent on quality of soil iiud 

 other cans -3. He had shaved trees 5 and 6 times, and 

 thought it quite possible a well-grown tree might be 

 shaved 50 times. He had tried varied experiments such 

 as fore-shortening the branches baring the roots iSro. 

 with various success, but had not yet been able to obtain 

 reliable information on the advantages of coveriug after 

 shaving. 



The Secretary gave the result of an experiment ia 

 covering, showing an analysis of .3'86 per cent for 

 covered bark, against analysis of 3-2G per cent for 

 uncovered bark. 



Mr. Jacksox stated that he had shaved trees in the 

 ordinary way from 3 to 5 years old, aud that it 

 had answered well, but that just now we were 

 trying what h« believed was a still better plan aud 

 re-shaving these trees • and leaving alt'sruate strips 

 (he always left one strip in shaving) and expected to 

 be able to fhave in this way every 3 mouths. Of 

 course this is Howard's plan. 



Mr. M-iKilN gave statistics of quantity of bai-k ob- 

 tained by coppicing trees in a clearing on Nanuoya 

 estate plauted in 1864, iu extfnt 'ij acres : — 



grds coppiced in 1874 yielding 7,0.57 lb. 



ird do. 1878 do. 6 457 lb. 



|rds recoppiced 1879 do. 13,000 lb. 



To date with Jrd standing 26,514 lb. 

 Experimental acre : — 



Trees, lb. S. Quin. 



18S1 shaved in May 1,742 = 705 showing 2'76 percent 



1882 do. do 1,610 = 516 do. 4-42 „ 



1883 do. in Feb. 1,600=600 do. 309 „ 

 Mr. P.tTBUsoN gave it as his opinion that it was 



not advisable to shave trees oftener tbau once in 

 12 months, his experience w.as chiefly derived from 

 officinalis aud he had obtained these results from trees 

 11 years old : — 



Origin.al shavings 1 'Oii per cent. Sulph. Qain. 

 1st renewal 5.76 ,, ,, ,, 



2nd do 7 05 ,, ,, ,, 



Other members gave their experience. 

 Mr. CAJirr.KLi. proposed, and Mr. J.\ckson seconded 

 the following rn.soluiion : — "That a Sub-Committee be 

 appointed to draw up a list of questions aud form a 

 report on cinchona culture iu Dimbuli." 



Mr. Ani<hksox propos»d, and Mr. Klphinstone 

 seconded: — '■ That the following,' gentlemen form the 

 Sub Committee : — The Chairman and Secretary and 

 Messrs. .'\. Canllay. W. Smith, A. Campbell, Jackson, 

 Martin, Symouds, Maitland and P«terson." — l^arried.
