THE NURSERYMAN’S LITERATURE. 
In these busy days of competition and progressive activity 
the nurseryman can hardly find time to peruse all that is pub¬ 
lished upon the subject of horticulture. If he were to read all 
the periodicals that come to his desk he would have little time 
to attend to the details of his business. The large number of 
farm papers upon which ten years ago he was obliged to 
depend for information regarding his business now are found 
to contain so little of a practical bearing on his trade that if he 
esteems his time and opportunity he will dismiss them with a 
glance at the most, if he retains them at all, and will 
devote his attention to the condensation of trade topics per¬ 
taining to his business that appears in his trade journal. The 
comment of many of the readers of the National Nursery¬ 
man that this is the only horticultural journal which they read 
through shows that the progressive nurserymen are learning 
the truth of the argument that we have repeatedly made, viz: 
The official trade journal is a business publication for the 
business men of that industry, and is not a matter of enter¬ 
tainment or pleasure, except in that it affords pleasure to be 
posted on what is going on in the trade, and to be numbered 
among the supporters of a publication devoted all the time ex¬ 
clusively to the particular business in hand. 
TWO INSECTS THAT COST $4,000. 
Attention has been called in the National Nurseryman to 
the fact that C. L. Marlatt, assistant entomologist of the U. S. 
Department of Agriculture, had sent to the department head¬ 
quarters in Washington seventeen ladybirds found in China 
and believed to be a parasite of the San Jose scale. These 
insects arrived last fall and were carefully tended, but before 
egg-laying time this spring all died with the exception of two 
females. These have laid many eggs which have hatched and 
the larvse have been feeding on scale insects provided for them. 
It is expected that the ladybirds will have increased largely in 
numbers by next fall. A test in orchards affected by the San 
Jose scale will be made with the ladybirds and it is hoped that 
the latter will be as destructive of the scale insects in this 
country as they have been in China. 
The two female ladybirds which survived have cost the 
government $ 2,000 each, it is said. If the brood which they 
have started should be the forerunner of an effective enemy of 
the San Jose scale, the cost will be very small compared with 
the benefit. Nurserymen as well as orchardists will await 
results with interest. 
A THREE DAYS SESSION. 
The prospect is that when President Robert C. Berckmans 
drops the gavel at 11 o’clock on the morning of June nth in 
the assembly hall of the Plankinton hotel at Milwaukee, one 
of the most successful and most largely attended conventions 
of the American Association of Nurserymen will have opened. 
The indications are that there will be a large representation of 
the membership of the Association. Milwaukee is a favorable 
place for the convention, with ample accommodations and but 
a short distance from the central city, Chicago. 
It is the desire of the president and of those who have the 
matter directly in hand to have a three days convention. It is 
probable that the programme will be arranged in accordance 
with that plan. It has been proposed to hold the sessions of 
the convention in the forenoons only, with perhaps the excep¬ 
tion of the first day. With morning and afternoon sessions on 
Wednesday, a morning session on Thursday and another on 
Friday, it is thought that more can be gotten out of the pro¬ 
gramme and more also out of the time spent in the convention 
city. Thursday and Friday afternoons can be devoted to 
entertainment which, it is understood, will be provided in 
some way by the enterprising citizens of Milwaukee through 
its very active and efficient Citizens Business League of which 
R. B. Watrous, whom many of the nurserymen met at the 
Niagara Falls convention last year, is the secretary. The 
evenings also will afford time for the renewal of acquaintances 
and business and social discussion. 
Secretary Seager has secured the promise of addresses on 
practical topics by Professor L. H. Bailey, of Cornell Uni¬ 
versity, Ithaca, N. Y.; Hon. N. H. Albaugh, Phoneton, O. 
Hon. A. L. Brooke, North Topeka, Kans.; and Professor
