THE NATIONAL NURSERYMAN. 
what strength of hydrocyanic acid gas can be used on nursery 
stock without producing injury. Low grade and June budded 
peach trees are injured by gas stronger than 16 grains per cubic 
foot, while well-matured, dormant peach will stand four times 
this strength—25 grains are used in all regular nursery fumi¬ 
gation. Apples resisted six times this amount under an expo¬ 
sure of one hour. Still, all work should be done by accurate 
measurements of the fumigating enclosures and bv the weigh¬ 
ing of fumigating materials, for no guesswork can be allowed. 
The system has been adopted by the Province of Ontario, Prof. 
William Lockhead having visited Maryland to observe its 
workings and learn its details, and putting it into operation by 
starting 60 houses witnin 30 days after his return; and he re¬ 
ports recently that it is working nearly to perfection.

The twelfth annual report of the Maryland Experiment Station con¬ 
tains a report by Prof. Willis G. Johnson, entomologist, on the San 
Jose scale in Maryland, and remedies for its suppression and control. 
The report is illustrated with engravings of peach orchards in which 
thousands of trees have been killed by the scale. Fumigation is recom¬ 
mended and the process is described with illustrations. The distribu¬ 
tion of the scale in the counties is noted. A list of 41 nurserymen of 
Maryland is given. 
The Florists’ Manual, b} r William Scott, a reference book for 
commercial florists, has considerable interest for nurserymen. It 
gives, as its name implies, cultural directions, adaptability of purpose, 
choice of varieties, etc., regarding the leading plants handled by the 
florist. It is based upon thirty years’ experience in nearly every 
branch of the business, from selling a bunch of violets over the coun¬ 
ter to planting a tree, seeding a lawn or building a greenhouse, and the 
author has therefore touched on several features of the business besides 
the growing. The volume is profusely illustrated with photo-engrav-' 
ings which form ap attractive and valuable feature. The book is 
firmly bound and is printed on heavy paper with wide margins. 
Greenhouse building, store management, fertilizers, floral arrange 
ments, fungicide and packing plants and flowers are among the sub¬ 
jects treated. These and the cultural directions for each plant are 
alphabetically arranged. A photo-engraving of the author is the 
frontispiece. Half leather, 4to. pp. 235. $5.00. Chicago, Florists’

The proceedings of the eleventh annual meeting of the Association 
of Economic Entomologists have been officially published by the U. S. 
Department of Agriculture. At the outset is given in full the annual 
address of the president. Prof. C. L. Marlatt, first assistant entomo¬ 
logist of the U. S. Division of Entomology. Prof. Marlatt’s subject 
is: “ The Laisser-faire Philosophy Applied to the Insect Problem.” 
This is the address wffiich caused animated discussion at the conven¬ 
tion, reference to which has been made in the National Nurseryman. 
It occupies 14 pages of the report and is an able discussion of an 
important subject. I he views expressed in the discussion which fol 
lowed, as recorded by the secretary and subsequently revised by the 
participants, are given. They occupy 44 pages. Members of the 
association feared that the term laisser-faire might be misunderstood. 
Chief Entomologist Howard thought that on the whole the San Jose 
scale alarm had been productive of great good. A. D Llopkins con¬ 
gratulated the president upon his most interesting and suggestive 
address. He fully agreed that many of these national problems were
