tions on the spread of this disease in your 

 country. (Signed) Prof. Dr. K. Schil- 

 berszky.' " In reference to the foregoing. 

 Mr. A. S. Horne wrote: "It is interesting 

 to find that Professor Scliilberszky lias iden- 

 tified the disease which was recorded by Dr. 

 Giissow, of Newfoundland, as that described 

 by himself in potatoes derived from Upper 

 Hungary. Tliere are two points at issue in 

 Britain, concerned both with the disease and 

 the organism : (l^ Professor Schilherszky 

 stated in his published description that 

 crater-like depressions were formed in some 

 tubers. Symptoms of this kind were not 

 found in potato tumour in this country. (2) 

 At first spores of only one kind were found 

 in this country. It is a well-known fact that 

 tumours of a similar form may be caused by 

 different organisms. Tliere was confusion 

 between the tumour in heetroot, caused bv 

 Urophlyctes leproides, and potato tumour. 

 It was possible, therefore, that the tumour 

 in the British disease might have been due 

 to a different organism, or perhaps to more 

 than one organism, For these reasons in- 

 vestigators in England desired the personal 

 assurance of Professor Schilberszkv that 

 potato tumour was due to his Chrysophlyctis 

 endobiotica.'"

Present: Mr. E. A. Bowles. M.A., F.L.S. 

 (in the chair); Sir John Llewelyn, Sir 

 Everard im ITiurn, Dr. Rendle, Messrs. J. 

 O'Brien, W. Hales, C. Shea, G. Massee, G. 

 Goi'don, W. Cuthbertson, and F. J. Chitten- 

 den (hon. secretary). 



OBEROXIA SP.— Mr. J. O'Brien showed a 



species of oberonia from Uganda. It was 

 referred to Dr. Rendle for examinat^'on. 



ONCOBA ROUTLEDGEL— Mr. Shea re- 

 marked with reference to seedlings of this 

 plant, that of 17 raised by him from one fruit 

 15 M^ere spiny and two quite without spines. 



CCELOGYNE VENUSTA.— Sir Frederick 

 Moore sent an inflorescence of this interest- 

 ing species from Glasnevin. It is a native of 

 Yunnan. On the motion of Mr. O'Brien, 

 seconded by Mi'. Sliea. it was unanimously 

 resolved to recaiiimeiid the award of a Botani- 

 cal Certificate. 

 VIOLETS WITH BRANCHED PEDUN- 



Miss Dalton sent from Sway, Hants, 

 a number of violets bearing branched pe- 

 duncles, and apparently more or less fas- 

 ciated. They had been cultivated in the 

 ordinary way, but in some two or three 

 double flowers were produced at the apex of 

 the common peduncle; in others the peduncles 

 separated lower down. Several examples of 

 a similar nature have been sent to the com- 

 mittee during the present >eason from widely- 

 separated localities^ otherwise it apjiears that 

 violets are but rarely fascia ted. 



NEW ORANGE.— Mr. H. S. Rivers sent a 

 variety of orange newly introduced, known as 

 " Oousliiu." " Satsuma," and " Kii Seed- 

 hvss."" It is a Japanese variety somewhat 

 like a Mandarin. The somewhat flat /ruits 

 shown were from maidens, and tlie variety 

 's said to he almost hardy, ripening it.> fruit 

 very early. 'V]w skin is thin and de<'p \<

 A<Tf) (;AS. -Mr. Hale.-, referzed t*' >anie re- 



sults obtained at Chelsea Physic Garden lately 

 in fumigating with hydrocy-anic acid g-as. The 

 fumigation had been done on a very dull day, 

 and the house had not been damped down 

 for two days previous to the operation. Hie 

 fumigation was with material of ordinary 

 strength, but it had failed to destroy all the 

 mealy bug, and had caused considerable in- 

 jury to many plants, especially those with 

 somewhat succulent leaves, such as clivias. 



North of Scotland Horticultural 

 and Arboricultural Society. 



"Sweet Pea Cultivation" was the subject 

 of a most instructive lecture delivered to the 

 members of this association in the Botany 

 Classroom, Marischal College, Aberdeen, on 

 Wednesday evening, 21st inst., by Mr. John 

 G rigor, head gardener. Seapark, Forres, 

 Elginshire. There was an exceedingly large 

 attendance, and Mr. John McKinnon, Haddo 

 House, president, occupied the chair. In 

 introducing the lecturer, the Chairman re- 

 ferred to the very prominent place Mr. 

 Grigor had occupied in 8weet pea culture 

 during last season, he having carried off the 

 chief prizes at the leading horticultural ex- 

 hibitions in Scotland. 



Grigor, having thanked the meeting 

 for his kind reception, said his own experi- 

 ence was that a great deal of success in 

 sweet pea cultivation lay in the preparation 

 of the trenches, because if the soil were not 

 properly prepared, one need never expect 

 good exhibition blooms. Light, sandy soil 

 suited the sweet pea very well, although 

 it might remain longer in bloom in a heavy 

 soil. It was essential to secure fresh soil or 

 turf eaeh vear to fill' the trenches, the turf 



_ 



lieing stacked for a month or two before n^e. 

 Some growers dug out their trenches to a 

 depth of five or six feet, and others to a 

 depth of three fee-t. For his own part, he 

 did not think anything was to be gained by 

 deep trenching. He spoke from experience.- 

 and he favoured eighteen inches deop and 

 eighteen inches wide. The lecturer then re- 

 ferred to the preparation of the soil use-I 

 in filling the trenches, and said the composi- 

 tion he most favoured, and which he had 

 found highly successful, was two part; 

 filn'(uis soil, one part eaeh of sand and old 

 manure from mushroom beds, with a few 

 handfuls of charcoal. The best time for 

 sowing ee-ed for exhibition purposes was early 

 spring. They could either sow in pots or 

 boxes, but he favoured the latter method, as 

 "n his experience lie always r.bta'ned st^-onTC^^ 

 plants from seeds sown in boxes. By the 

 second week in ]\lar(di he liad his ]:eas trans- 

 ferred to a cold frame. The first week in 

 April he found wa> tlie most favourable ti?ne 



to start planting. 



Mr. Grigor then pro:'eeded to deal with 

 planting, staking, and feeding and wate' ing. 

 putting emphasis on tire la-t t\v;> as punts 

 of great ini]iortance if real sneeess wtne to 

 ])e ""atdiieved. ^ir. (h'igor eom^luded h*s 

 oreatly a]i])recia1 ed lecture by stating that, 

 under' the m-thod of cultivation he had de- 

 .crilxxl. his plant,, had always been healthy 

 and free fi^uu disease. 



AVarm eneomnims on the lecture were 

 passed bv :\lr. Alexander Robson. vice-presi- 

 dent, Mr. C. S. France, and others, aiid Mr. 

 Grigor was heartily thanked for hl^ very 

 interesting and educative lecture. 



Thereafter, the secretary, Mr. William 

 Reid. read a paper by Mr. Clark, King's 

 ('olleo-e Observatory, Aberdeen, entitled. 

 Meteorological Notes for the Year, and 

 ,^-^u> from the Drought of 1911." Mr. 

 ark tr.'ated his subject in a nmnner which 

 indicated how thoroughly e(tnv(M>ant lu^ wa- 

 with it. and characterised last -uonn-r a> 

 one of tlie brightest, wal■me^-t, and diie-st 

 seasons on record, tlie mean temi)eratMre ex- 

 eeeding the usual average. The hearty
