THE GARDENERS' CHRONICLE. 



[March 2, 1912. 



Gardeners 1 Royal Benevolent Institu- 

 tion.— Sir Jeremiah Colman, Bart., will preside 

 at the 73rd anniversary festival dinner in aid of 



paraded, and the great amphitheatre, where the 

 Durbar was held." Truly a good share in this 

 great epoch-making festival. The Guild mourns 



the funds of the Gardeners' Royal Benevolent the loss of one of its most distinguished mem- 



Institution on June 25, at the Grocers' Hall, 

 City, kindly lent by the Guild. Ladies will be 

 welcomed. 



Royal Gardeners* Orphan Fund. — Sir 



Edwin Durning-Lawrence, Bart., will preside 

 at the 24th annual dinner in aid of this fund, 

 which has been arranged to take place at the 

 Hotel Cecil on Wednesday, May 8 next. 



National Dahlia Society, — A Dahlia Con- 

 ference will be held by this society at Carr's 

 Restaurant, Strand, on Friday, March 8, at 6.30 



p.m 



Mr. George Davidson will read a paper on 

 " The Cultivation of the Dahlia in Suburban 

 Gardens," and Mr. J. B. Riding one on 

 11 Collarette, Pseony-flowered, and Decorative 

 Dahlias." Members of the society and others 

 interested in the Dahlia are invited to send ques- 

 tions before the conference to the Hon. Secre- 

 tary, Mr. E. F. Hawes, Ulysses, Fortune Green, 

 Hampstead. The questions will be answered at 

 the meeting after the papers have been read.

 built Kew gardens on foundations laid by his 

 father, Sir William Hooker. 



L.C.C. Parks. — The Education Committee 

 of the London County Council recently agreed 

 to co-operate with the Parks Committee by 

 selecting annually four boys from the public 

 elementary schools for employment in the London 

 parks. The head teacher of each provided and 

 non-provided school in London will be invited 

 to nominate one boy ; the final selection being 



Vegetable Growing in Canada.— A corre- 

 spondent in The Canadian Horticulturist states 

 that the culture of vegetables in Canada is 

 entirely different to the method practised in 

 Great Britain, " the climatic, customs of the 

 country, manner of growing, and marketing are 

 all different." He recommends newcomers to 

 learn the business for a year or two with some 

 grower in the colony. After gaining experience, 

 a capital of from 500 to 1,000 dollars is necessary 

 to carry on a market garden in the colony for 

 vegetable growing.

Compulsory Spraying. — The State of Ohio, 

 U.S.A., has passed a law, which comes into force 

 in May, requiring all orchards in which there 

 are 10 or more trees to be sprayed at least once 

 between November 1 and April 30. The pre- 



variety of publications through which results are 

 scattered, it is becoming more and more difficult 

 for any one individual to keep abreast of recent 

 work, or to appraise, at its true value, any par- 

 ticular paper not in his own branch. The 

 Syndics of the Cambridge University Press are 

 about to issue a series of monographs, to be 

 called the Farm Institute Series, each of which 

 is to contain a summary of the present 



The Phosphate Nutrition of Plants. 



Cultures of Oats and Peas provided with phos- 

 phates of different kinds, namely, ferric phos- 

 phate, aluminium phosphate, and calcium 

 phosphate, appear to show that the two former 

 compounds are far more effective phosphatic 

 fertilisers than is calcium phosphate. The ex- 

 periments were made by Mr. Allan Baguley, 

 and the results, which are published in the 

 Journal of Agricultural Science (January 3, 

 1912) show that, whereas pot plants of Oats 

 and Peas grown with ferric or aluminium phos- 



made good growth, those supplied 



paration used must be such as will destroy San agricultural science by an expert of acknow- P . . , , . .- ■ - .., ^;« ft *^ h*A\v

It should be observed, however, that in the case 

 of Peas, super-phosphate gave better results than

Kew Guild "Journal." — Although this 

 Journal is concerned only with the doings of 

 Kew men, it will be read with interest by 

 every gardener. The frontispiece of the issue 

 for 1911-1912 is a portrait of Mr. E. A. 

 Eolfe, accompanied by a biographical note 

 of this well-known orchidist. The family 

 affairs of the guild include accounts of the annual 

 meeting and dinner, also the records of the 

 Mutual Improvement Society and sports clubs. 

 Kew has a more cosmopolitan character 

 than any other garden in the world, and 

 the notes from old Kewites contributed from 

 remote quarters of the globe are always 

 interesting. It is not surprising to find that 

 Kew was well represented at the recent 

 Coronation festivities in India. [Mr. A. E. P. 

 Griessen, writing from Durbar Gardens, Delhi, 

 states : "Johnson came up from Calcutta, 900 

 miles, to lay out the Government of India and 

 Bengal camps ; Little from Bombay, 950 miles, 

 to attend to the Government of Bombay camp ; 

 Krcmbiegel from Mysore, 1,500 miles, 

 Cavanagh from Baroda, 800 miles, to carry out

Sulphur for Use with Copper-contain- 

 ing Spray Fluids.— Sulphur suspended in water 

 to which soft soap is added has the drawback, 

 when used for mixing with copper sulphate or 

 Bordeaux mixture, of not being wettable by the 

 metallic salts. Messrs. Vermorel and Danbury 

 (C. R. Ac. Sc, Paris, cliii., p. 194) recommend 

 instead of soap the use of a solution of oleic 

 acid — the oleine of commerce — made by dis- 

 solving 200 cc. (about ^ pint) in two litres 

 (3J? pints) of methylated spirits. This solution 

 serves to wet about 200 lbs. of sulphur. 



Chesterfield Chrysanthemum Society. 



— At the annual meeting, held on the 20th ult., it 

 was unanimously decided to wind up this society. 

 W. F. Hewitt, Esq., the hon. treasurer, pre- 

 sented the audited accounts, which were adopted, 

 showing a balance in hand of £21 6s. 3d. On the 

 proposal of W. T. G. Btjrr, Esq., it was decided 

 to distribute this amount as follows : — £10 to the 

 Eoyal Gardeners' Orphan Fund, £5 5s. to the 

 Gardeners' Royal Benevolent Institution, and the 



their respective camps; Mustoe, from Lahore, remainder to the Chesterfield Hospital. The f ol- 

 500 miles, to bring the Punjab camp to its beauty lowing sums have been given to charities since 



ful setting. Leslie from Nagpore also turned 



up for the Central Provinces camp, and Head 

 from Allahabad. Locke, who is resident here, 



the formation of the society in 1893 : — Royal 

 Gardeners' Orphan Fund, £231 lis. 6d. ; Gar- 

 deners' Royal .Benevolent Institution, £184 16s. ; 



had his share of the work to attend to, that Chesterfield Hospital, £85 ; and for placing seats 



which appertained to the local authorities. As 

 to myself . . . our biggest undertakings were 

 the laying out of three polo grounds, review 

 ground, where fully 2,000,000 men could be 



in Queen's Park, Chesterfield, &c, £25 15s. 3d. 

 Many regrets were expressed by the members that 

 it was no longer possible to successfully continue 

 the show. 



latter fertilisers proved the better in the case 

 of Oats. It would seem worth while experi- 

 menting with these phosphates on lawns which 

 are deficient in phosphatic compounds. 



Tomato-leaf Rust.— An illustrated account 

 of this disease is given in the current number of 

 the Journal of the Board of Agriculture. This 

 troublesome pest is well known in this country to 

 growers of Tomatos under glass, and it is pre- 

 valent also in other countries of Europe and in 

 the United States. The disease is due to the 

 fungus Cladosporium fulvum (see Gard. Chron., 

 October 29, 1887, figs. 106, 107). It attacks the 

 leaves, stem, and fruit of the Tomato plant, the 

 leaves being particularly liable to injury. The 

 fungus first appears on the leaves in the form o 

 spots, which increase in size and become darker 

 in colour. The spores are produced in enormous 

 numbers on the under-surface of the leaves, to 

 which they give a rust-coloured appearance. l n€ 

 disease spreads with great rapidity. Spra\ 

 should be done in the earliest stages of attack, or 

 it will be of little use. The need of covering the 

 entire surfaces of the plants with the fungicide is 

 emphasised, and, consequently, repeated applica- 

 tions of the spraying fluid are advised. Growers 

 are recommended to use Bordeaux Mixture 

 half-strength when the plants are young, an 

 liver of sulphur, 1 ounce in 4 gallons of wat<? /^ 

 when flowers and fruit are present. - It ma} 

 noted that, although this disease is kno\v» 

 amongst growers as Tomato " rust," the fung 

 causing it is not related to rust fungi proper.
