MANUAL OF VEGFTABLF GARDEN INSECTS 
Manual of Vegetable-Garden Insects is the title of a 
book just published by the MacMillan Co., 66 Fifth Ave., 
New York, by Cyrus Richard Crosby and Mortimer Dem- 
arest Leonard of the New York State College of Agricul¬ 
ture at Cornell University. This is one of the rural 
manuals edited by Prof. L. 11. Bailey. 
The contents are arranged in a very practical and easy- 
to-get-at-way, the insects being grouped under the vege¬ 
tables they attack, for instance, those injurious to the- 
cabbage and related crops, pea and bean insects, those 
that attack the cueumber, squash and melon, potato in¬ 
sects, etc. 
This arrangement makes it possible to very readily 
identify the pest that is causing the damage and give the 
necessary treatment to control it. 
There are also chapters on cut worms, and army 
worms, blister beetle, flea beetle, and unclassified pests. 
The work should prove of immense value to the vege¬ 
table gardener. It is veiy thorough and its use should 
prove a valuable insurance against failure and loss of 
Cl ops on account of insect pests. 
The chapter on insecticides gives an account of the 
more important materials now employed, the directions 
for their preparation and use. The price of the book is 
$2.50. 
MANUAL OF TREE DISEASES 
Tliere have been a good many books and papers pub¬ 
lished on the subject of diseases of trees and plants. 
Many of them, however, are such as it is not easy for the 
layman or even the professonal to refer to, and readily 
obtain the specific information he desires. 
We are just in receipt of a copy of Manual of Tree 
Diseases by W. Howard Rankin, A. B. Ph. D., one of the 
rural manuals edited by Prof. L. 11. Bailey, and published 
by the MacMillan Co., 66 5th Ave., New York, price 
$2.50. 
The book is so arranged that it is easy to find what the 
student is looking for, as the diseases are arranged under 
the trees they attack. Ash diseases. Chestnut diseases, 
Birch diseases, etc. In other words, if you have a dis¬ 
eased tree and know the common name of it you can 
readily refer to the diseases which attack it and by the 
help of this book, identify it and learn the treatment ne¬ 
cessary to combat it. 
There is a chapter on tree surgery, which we thor¬ 
oughly endorse, as there has been a tendency of late 
years to give this work rather more importance than it 
is justly entitled to in the care and health of trees. 
It is a splendid work for the student, and in fact, for 
anyone interested in arboriculture. 
CAPITAL AND LABOR 
A convention was recently held at Atlantic City under 
the direction of the Chamber of Commerce of the United 
States made up of 400 War Service Committees which 
will act in the future as the spokesman for industry be¬ 
fore the government on the subject of industrial rela¬ 
tions. 
The convention heartily endorsed in letter and spirit 
the principles of the industrial creed so clearly and for¬ 
cibly stated in the paper read to it by 
Mr. John D. Rockefeller, Jr., and urges upon all units 
of industry,—where they may not now be employed,— 
the application of such principlees. Without approving 
or rejecting his particular plan or machinery, the prin¬ 
ciples advaneed by Mr. Rockefeller are as follows: 
1. Labor and capital are partners, not enemies; their 
interests are common interests, not opposed, and neither 
can attain the fullest measure of prosperity at the ex¬ 
pense of the other, hut only in association with the other. 
2. The purpose of industry is quite as much to ad¬ 
vance social well-being as material well-being and in 
the pursuit of that purpose the interests of the commun¬ 
ity should he carefully considered, the well-being of 
the employes as respects living and working conditions 
should be fully guarded, management should be ade¬ 
quately recognized and capital should be justly compen¬ 
sated, and failure in any of these parteulars means loss 
to all, 
3. Every man is entitled to an opportunity to earn a 
living, to fair wages, to reasonable hours of work and 
proper working conditions, to a decent home, to the op¬ 
portunity to play, to learn, to worship, and to love, as 
well as to toil and the responsibility rests as heavily upon 
industry as upon government or society to see that these 
conditions and opportunities prevail. 
4. Industry, efiieiency, and initiative, wherever found, 
should be encouraged and adequately rewarded and in¬ 
dolence, indifference, and restriction of production 
should he discountenanced. 
5. The provision of adequate means for uncovering 
grievances, and promptly adjusting them, is of fun¬ 
damental importance to the successful conduct of in¬ 
dustry. 
6. The most potent measure in bringing about indus¬ 
trial harmony and prosperity is adequate representation 
of the parties in interest; existing forms of representa¬ 
tion should be carefully studied and availed of in so far 
as they may be found to have merit and are adaptable to 
the peculiar conditions in the various industries. 
7. The application of right principles never fails to 
effect right relations; the letter killeth and the spirit 
maketh alive; forms are wholly secondary while at¬ 
titude and spirit are all important, and only as the par¬ 
ties in industry are animated by the spirit of fair play, 
justiee to all, and brotherhood, will any plans which they 
may mutually work out succeed. 
8. That man renders the greatest social service who 
so cooperates in the organization of industry as to afford 
to the largest number of men the greatest opportunity for 
self-development and the enjoyment by every man of
