erly displayed. Give him all he is en- 

 titled to and as much more as you can. 



It is too much to expect that many 

 distant firms will keep up their exhib- 

 its s^ter the convention year. Yet 

 some of the wide-awake and progress- 

 ive growers will undoubtedly be glad 

 to make use of our gardens permanent- 

 ly and thus exhibit their goods and 

 special novelties in different parts of 

 the country at the same time. In 

 most instances it will, therefore, be- 

 come desirable and necessary, after the 

 first year, to change the layout of the 

 garden and to devote the larger part 

 of the grounds to hardy material, and 

 a much smaller portion to the tender 

 annual bedding plants. 



This we have done at Minneapolis 

 and the new layout will be as beautiful 

 and instructive to our people from now 

 on as the real convention garden was 

 to us professionals two years ago. 



Under Society's Auspices. 



The convention garden must, in my 

 opinion, always be created and main- 

 tained under the auspices of the na- 

 tional society. The price for space 

 should, if at all possible, be the same 

 wherever the garden is, and should be 

 high enough to defray the expense of 

 maintenance. The chairman of the 

 local garden committee should be ap- 

 pointed a member of a similar commit- 

 tee of the S. A. F., and as such could 

 act as the executive officer of both" 

 committees. 



The garden should be located on pub- 

 lic land, in order to make its future ex- 

 istence possible, and I know of no good 

 reason why every city park administra- 

 tion should not be not only willing, 

 but really anxious, to cooperate with 

 us in the establishment of such trial 

 and exhibition grounds, which cannot 

 help being of educational value to the 

 people of their city. 



Our esteemed president, Patrick 

 Welch, has assigned to me the subject 

 herein presented, but I am not sure 

 that I have covered the ground to his 

 entire satisfaction. There are really 

 no great problems, no great obstacles, 

 that I can see, attending the establish- 

 ment of permanent convention gardens, 

 and I believe that if the old saying, 

 "Where there's a will, there's a way," 

 is applied at all times, there can never 

 be any doubt as to our ability to 

 establish such conventidn gardens wher- 

 ever we may go, and to make them 

 successful in every instance. 



ENTOMOLOGIST'S REPORT. 



[The following is the report of Dr. W. E. Brit- 

 ton, entomologist of the S. A. V., presented at 

 the San Francisco convention. August 17, 1915.] 



All who have been troubled by the 

 chrysanthemum leaf-miner, or marguer- 

 ite fly, Phytomyza chrysanthemi Ko- 

 warz., should obtain bulletin- No. 157 

 of the Massachusetts Agricultural Ex- 

 periment Station, Amherst, Mass., is- 

 sued recently. 



For the last twenty-five years this 

 insect has caused damage to composite 

 plants in the northern states. The 

 adult is a 2-winged fly which lays an 

 egg in an incision just under the epi- 

 dermis of the leaf. This egg hatches 

 * in five days, and the larva mines in 

 the parenchyma of the leaf for about 

 two weeks, when it transforms to the 

 pupa stage inside the leaf. Two weeks 

 later the adult emerges. There are ten 

 generations each year. 



Spraying the plants with nicotine so- 



lution is a remedy. If Black Leaf 40 

 is the kind used, it should be diluted 

 at the rate of about one part in 400 

 parts of water, or roughly two tea- 

 spoonfuls in a gallon. 



Another chrysanthemum pest new to 

 our continent is the chrysanthemum 

 midge, a European insect which has re- 

 cently caused much damage in some 

 large commercial greenhouses in Mich- 

 igan. The presence of this insect was 

 recorded by Dr. E. P. Felt, state en- 

 tomologist of New York, in the Flo- 

 rists ' Exchange, Vol. XXXIX, page 856, 

 April 10, 1915. It causes a swelling on 

 the main stem near the surface of the 

 ground, galls or enlargements on the 

 midribs of the leaves, and close, ill- 

 shaped heads, which ruin the plant for 

 commercial purposes. It will probably 

 be difficult to control this pest. 



Further injury to chrysanthemums 

 may be here recorded by a mite, Tar- 

 sonemus pallidus Banks, mentioned in 

 my report of last year. This time it 

 occurred in October in a commercial 

 greenhouse at Hartford, Conn., and 

 many of the petals had withered and 

 turned brown. 



New Pest on Pines. 



During the last year one of the de- 

 structive European sawflies, Diprion 

 (Lophyrus) simile Hartig, has been 

 found in this country, where it has 

 apparently become established. The in- 

 sect passes the winter in its cocoon 

 on or under leaves and rubbish near 

 the ground. There are apparently three 

 broods each year in Connecticut, the 

 cocoons of the first and second broods 

 often being formed on the twigs. The 

 larva; are about an inch long, green- 

 ish yellow with brown markings, and 

 have the appearance characteristic of 

 sawfly larvae. They feed upon the 

 needles of several species of ^ine, in- 

 cluding the white pine, Austrian pine, 

 Pinus densiflora, ,P. excelsa and P. 

 flexilis. It will doubtless be found to 

 attack other species as well. 



The eggs are laid in longitudinal in- 

 cisions in the needles and are placed 

 end to end. 



The cocoons are brown oval bodies 

 about three-eighths of an inch long and 

 of a tough, leathery texture. 



The adults have a wing-spread of 

 from about half an inch in the male to 

 three-fourths of an inch in the female. 

 The male is black, but the female has 

 yellow thorax and abdomen. 



Though this insect occurs in four 

 towns in Connecticut, it will probably 

 be found in other states. Just how it 

 was brought to this country is not 

 known, but probably cocoons came over 

 on nursery stock and either passed the 

 inspectors or perhaps came in before 

 the inspection system was established. 

 Parasites of this sawfly have been ob- 

 served in Connecticut. Spraying the 

 pine trees with lead arsenate, three 

 pounds in fifty gallons of water, is the 

 best remedy. 



A preliminary illustrated account of 

 this insect may be found in the Journal 

 of Economic Entomology, Vol. 8, page 

 379, June, 1915. 



Juniper Web Worm. 



Several samples have been received 

 by the writer of juniper twigs webbed 

 together by a juniper web worm. On 

 rearing the adult, it proved to be Dich- 

 romerus marginellus Fahr. Dr. E. P. 

 Felt has recorded this insect from (Long 

 Island and from the Hudson river val- 



ley in New York state. This is also a 

 £Juropean species which has appeared in 

 the United States during the last few 

 years. The real damage from it will 

 be in ornamental plantings in parks and 

 on private grounds, and doubtless may 

 be prevented by a thorough spraying of 

 lead arsenate early in spring and again 

 late in summer. 



REPORT ON SMITH MEMORIAL. 



[The following Is the report of Wm. F. Gude, 

 chairman of the committee on the Wm. R. Smith 

 memorial, presented at the San Francisco con- 

 vention, August 17, 1915.] 



On account of the general depression 

 in business all over the United States 

 and further on account of various other 

 disturbances throughout the world, 

 which affect us generally, the memorial 

 committee thought best not to push 

 the project during the last year.

Your committee feels hopeful of re- 

 ceiving some good sums from influen- 

 tial citizens and a liberal support from 

 the Congress of the United States. 



Your committee has not decided what 

 form of a memorial to suggest, as their 

 decision will no doubt be largely gov- 

 erned by the amount of subscriptions 

 collected and government influence that 

 they may be able to secure. 



Columbus, O. — H. C. Phelps is to erect 

 a range of greenhouses at his country 

 place near here. 



WUting, Ind. — Louis E. Klemm and 

 his wife, of the Klemm Greenhouses, 

 have returned from a most delightful 

 trip through Virginia. Mrs. Klemm, 

 who was recently quite ill, is now mak- 

 ing an uninterrupted recovery. 



Kenosha, Wis. — Louis Turner & Sons 

 have moved into their new location in 

 the Flatiron building. They now have 

 one of the most up-to-date stores in the 

 state. All decorations are in white. 

 The store was formally opened August 

 14, when, it is estimated, 5,000 people 

 passed through its doors, each lady re- 

 ceiving an American Beauty rose and 

 each gentleman a carnstio« as a sou- 

 venir.
