 more widely extended. — Believe nie, very faithfully

[There can be uo question tbat the unequal size, often, 

 of the Liberiau beans renders the process of pulping 

 difficult. Messrs. W. Forbes Laurie, W. Leeohman 

 and others can aSord the information desiderated by 

 Mr. Morris, and we have uo doubt that ihe leading 

 pulper niauutactiirers of the world, Messrs. John 

 Walker & Co., will be able to meet and overcome 

 the dilBcuIties. — Ed ] 



THE CULTIVATION OF CINCHONA : 

 SCHROTTKY'S EXPERIMENTS. 



To the Editor of the " Cliemkt and Drugyist." 



Sir, — Referring to Dr. Cochran's letter to the Analy.it, 

 inserted in your last issue (p 249), the following in- 

 formation may be of some interest : — 



I have just completed the analysis ot two sets of 

 succirubras, each set consisting of 100 trees — one set 

 being treated according to Mr. Sohrottky's method, 

 the other not : — 



Quinine 

 Ciuchonidin 



Cinchonin ... 



Quinidin 

 Amorphous 



Total 5-40 ... .5-27 



Practically the two sets are identical, and are remark- 

 ably accordant for two sets of similar trees. Possibly 

 Mr. Cochran did not have the opportunity of analysing 

 such a large quantity ot trees ; and experience has 

 shown that two succirubras, identical as regards age, 

 appearance, growth, &e., differ very widely from one 

 another in the percentage of quinine, &c. 



At the Slime time it is possible thut this particular 

 set of trees were not under suitable or favourable con. 

 ditions for enjoying the benefit of Mr. .Schrottky's 

 no.'^trums, and that later on we shall find that he is 

 right in liis experiments. 



The I'oUowing analysis of some ''hybrids," &o. , for- 

 warded at the same time from Ceylon, may also be of 

 interest : — 



No. 1. — Six-year old tree, Pata de Galinazo tjpe. 



No. 2. — Dark shining leaf, succirubia shape, but not 

 wrinkled. 



No. 2e. — Hybrid, succirubra type. 



No. 3. — Hybrid, pendant branched, condamiiiea type 

 of leaf, rough bark. Seven years old. 



No. 3b. —Hybrid, a good deal of officinalis type. 



No. 6b. —Hybrids Nos. 1, 2, 3, and 4. Six to seveii 

 years old.

Indo-China Tea Associ.\tion.— Some short time since 

 we noticed the openiui; of the first four retail eslba- 

 lishments of this Company for .sale of tea to the 

 public. The Association now announces that it is pre- 

 pared to uiidertake the con-igumen' and s de upon the 

 home market of teas direct from the plantations, and 

 to enter into special arrangements with planters «ho"e 

 teas are suited to the requirements of their establish- 

 inents. — Overlaiul Mail.

 with diluted vinegar.— Indian World. 



The Sale op Valuable Seeds from .^onth America by 

 Mr. C. E. H. Symons, of Colombo, was, we are sorry to 

 lefiru, not a success owing t) the cinchona calisaya 

 Morada seed having come to hand in tlie husk instead of 

 "clean," as was expected. It was deemed advisable to 

 have the seed cleaned and it will be offered for sale again 

 next Saturday. The maize seed sold at R5 per ounce 

 and some of the coca at the same rate, There were 

 no bids for the other seeds. The Java ledger seed 

 sold at an average of 80 rupees per ouuce. 



The Lieerian Coffee Pulpeks made by Messrs. 

 J. Walker & Co., Mr. Morris will be glad to know, 

 it is confidently predicted, will do for Liberian whai 

 their other machines h,xve so successfully done for 

 Arabian coffee. Tlie following are a few advantages se- 

 cured by the Liberian cofite pulpers : — 1st.— They are 

 simple and all the working parts are ea.sily got at. 

 2ud. — They are substantial ; are not likely to get out 

 of Older, and can be driven either by hand or by 

 power. 3rd.— They do tlieir work thoroughly and 

 without damage to good coffee. These pulpers are 

 made in sizes to suit requirements from £18 to f 130 

 in price, and pulping from 10 to SO bushels per 

 hour. 



Enemie.s OF Tea in Japan.— Towards the latter end 

 of last Slay destructive green worms made their ap- 

 pearance in the tea plantations at Uji. They turned 

 into butterflies and spread rapidly by the middle of 

 June. Mr. Kitagaki, the governor, and some officials 

 of the ii.dnstrial Buieau, visited the plantations, and 

 by their advice and example induced the people to 

 engage in a general slaughter of the obnoxious insects. 

 At length it was thought they were all killed, and 

 then to make sure of extirpating them the governor 

 offered a reward of 4 rin for every worm or butterfly 

 produced at the Fueho. The whole neighbourhood 

 then turned out, and engaged in the cliase with such 

 vigour and success that in a short time over 120,000 of 

 these insects were brought in, and a bill of over 600 

 yen incurred. — Hiof/o News translation. 



Jc/TE Preparations.-- We believe that it is the 

 intention of the Bengal Government to procure at as 

 early a date as possible one of Messrs. Dennis and 

 Angell's machines, a short description of which we 

 reproduced in our columns on the 25th .Tuly. Should 

 the machine be equal to all that is claimed for it, it 

 will certainly effect a considerable change in jute 

 manufacture and filire manufacture generally as at 

 present practised. The Minister at Washington has as 

 yet been unable to procure Dennis and Angell's fibre 

 preparing machine, as it is still imperfect in many 

 details and consequently the inventors are not pre- 

 pared to offer their machines for sale. As soon, how- 

 ever, as the machines are in the market, one will 

 be procured, as we have said, by the Government.

Gums and Re,sin.s — In order to ascertain the free 

 commercial value of the gums and resins to be ob- 

 tained in the forests of this Presidency, a collection 

 made by the officers of the Forest Department, was 

 forw.ai lied by the officers of the Local Government to 

 Her lifajesty's Secretary of State for India for ex- 

 amhiation and report, by competent authoiities in 

 LondfMi. On an-ival in England, the samples were 

 handed over to Messrs. Burgoyne, Burbridge, Cyriax 

 and Ferries, of Coleman Street, London, liiid from 

 their report it appears that the gums of Acacia 

 leucophlea. (Salem) ; Ailantlius malabarica, Bassia 

 latifolia, Bombax malabarica, (Wynaad); Hardwickia 

 binata, (Salem); JSIoringa ptervgosperma, (Trichino- 

 poly); Buchanania latifolia, (C.ddapali); and some 

 others, were found to be of very low quality and 

 not worth importing. — Madras Mail.
