DISCUSSION. 



The discussion was opened by Mr. A. \\. 

 Sutton V.M.H., who had contributed to the 

 renort presented to the conference a va-luaible 

 ISenient embodying the information ^- 

 avdved by his firm in the course of their ex 

 Sort trade relating to the regulations affect- 

 ts the importation of seeds. and nursery 

 fitw;k that are imposed in various parts ot 

 the world M.T. Sutton said he considered 

 that some restrictions on imports are re- 

 nuired but he felt that, in many cases, they 

 are imposed far beyond what was necessary 

 or desirable. The great diversity in the 

 restrictive measures rendered it extremely 

 difi&cult for those who were not in a position 

 to obtain the fullest information to become 

 acquainted with them. In many cases, the 

 restrictions were probably for the purpose of 

 rorotecting the growers from competition 

 rather than their crops from insect enemies 

 or disease. In New Zealand nothing was 

 required beyond a certificate from the coun- 

 try of export. He considered it, however, a 



actments bearing on plant diseases. Tlie 

 lotion was seconded by Sir Daniel Morris, 

 and carried unanimously. 



The Chairman proposed votes of thanks to 

 the Chelsea pensioners for vacating their 

 Recreation Hall for the two days over which 

 the conferences had extended, to the readers 

 of papers, and to Mr. J F. Chittenden for 

 the splendid work he had accomplished as 

 hon. secretary of the Science and Education 

 Committee. These, on being put to the 

 meeting, were passed with acclamation. On 

 the motion of Professor I. Bayley Balfour, a 

 hearty vote of thanks was accorded the 

 Chairman. 



SCIENCE AND EDUCATIONAL 



EXHIBITS* 



An interesting exhibit from the Horticul- 

 tural Department, Reading University Col- 

 lege (Mr. Drew), showed suitable stocks for 

 various fruit trees; best methods of train- 



Veitch and Sons, Chelsea, show^ how 

 fairly wide is the effective range of stocks 

 upon which scions may be grafted ;photinia 

 on eotoneaster,lycopsisonhamamelis, arthro- 

 taxis on cryptomeria, pyrus on cotoneaster, 

 Crataegus on cotoneaster, and hippophae on 

 eleagnus, were a few very interesting and 

 successful graft experiments. 



From the Royal Botanic Gardens, -txlin- 

 burgh came a wonderful series of unusual 

 examples of successful plant propagation; 

 the formation of bulbils in bulbs, rooted 

 sterculia cuttings, acanthus leaf cuttings, 

 stem cuttings in endless variety, runners, etc 

 etc. Dr. Winifred Brenchley, of Eothamstead, 

 showed water cultures; and experiments re- 

 presenting the results of sterilisation of sick 

 soils also came from Rothamstead, and 

 created a great deal of interest. Numerous 

 exhibits from Reading and elsewhere showed 

 tiie progress of silver leaf disease, but, so far 

 as we could gather, little progress in the 

 prevention of the disease has yet been made. 

 The Board of Agriculture sent maps and

AN 



FECTIVE ROCK GARDEN. 



Designed and formed by Messrs. Pulham and Son 



serious matter that when a consignment of 

 potatoes, for example, was certificated after 

 careful examination free from disease, that it 

 should not be allowed to land because some 

 portion thereof was found to be infected 

 owing to the development of the disease dur- 

 ing the voyage. 



Sir F. Moore said there had -been much 

 difference of (>pi nion w ith regard to the 

 value of certificates, and it was contended by 

 some that many were worthless. He was 

 gratified to find* that there was some change 

 of opinion on the question, and was also glad 

 to find that growers were beginning to re- 

 cognise the fact that it was to their interest 

 to stamp out disease. 



Mr, W. J. Lobjoit, Professor Potter, Pro- 

 fessor E. G. Salmon, and Mr. C. E. Pearson, 

 also spoke, and at the close of the discussion 

 Professor Keeible proposed a resolution to the 

 effect that the Science and Education Com- 

 ttiittee be requested to remain in beijig, and 

 to confer with the Board of Agriculture with 

 a view to officially summoning an interna- 

 tional conference to consider tlie means of 

 simplifying and consolidating legislative en- 



tive 



ill?- the difference between disbudded and 

 undisbudded peaches, etc. ; inarching and 

 other methods of vine propagation, etc. Mr. 

 George Masse^'s paintings of vanoxis fungus 

 dSafes proved most interesting and mstruc- 



while the series of dried plant specimens 

 showing fungus infestations, frojnjil. H. 

 Eicke Frankfort, would have raised the hair 

 of a plant diseases inspector. An ingenious 

 2t of'^ nstruments for recording the rate of 

 plant growth, the amount of water lost by 

 l %nt by evaporation, etc., was vastly m- 



''Mr.'l^ Cheesman, the b^Jler at East Burn 

 ham Park showed a quamt exhibit ot a % ast 

 raTee of seedlings, largely oi trees, grown in 

 water ^n receptlcles of all kinds and sizes ; 

 besides these there were carrot, beet, and 

 pax4nip tops in water, and -en potatoes in 

 water all giving suggestions that scnooi

 From the Agricultural CoUege, Wye came 

 a most instructive exhibit of insect a^d allied

 Enocic and Prof. Newstead showed series of 



fns^ts that prey on i-j-i--, 



tropical scale injects respectively. A set ot 



the "Eeichenbachia" exhibited by Mr. F 

 Sander St. Albans, together with some of 

 ttriate Mr. H. G. Moon's original pamt- 



of orchids figured in that wonderful 

 work made book-lovers envious and covetous. 



rseries of berberis seedlings, showing the 

 effects of careful working on Mendelian

 and new types of vegetables, staged by 



Sutton and Sons, Beading, gave 

 demonstrations of the advances made 

 during recent years. Tlie wild cabbage, old
