GUARANTEE LABELS 
Guarantee labels on enameled ironware are various and are variously 
translated in practice. 
Careful architects have come to understand that it is the spirit 
behind the guarantee that counts for most after all. 
The liberal, 
unquestioning, make-good policy behind every Wolff guarantee is 
responsible for unvarying Wolff specification as often as is the 
leadership of Wolff design.

a book of descriptions, but a discussion of 
the architectural treatment of exteriors. The 
limitation is an important one, since it would 
obviously have been impossible to describe in 
detail the entire contents of a hundred houses 
within any reasonable compass, and the ex- 
igencies of book-making have again necessi- 
tated a definite limitation. This limitation 
need not, however, be regretted, for the out- 
side of the house is, in many respects, its most 
important part, and the same sympathetic dis- 
cussion of these exteriors is the best kind of 
architectural criticism, presented with the 
friendly appreciation of the man who knows 
his own mind and who himself is a master 
of the craft of which he writes so delightfully. 
For Mr. Embury’s book is delightful in 
every way. His photographs are charming 
and admirably selected, and his text con- 
fessedly critical, yet always appreciative— 
since he concerns himself only with houses 
meriting commendation—is charmingly writ- 
ten. It is a book that must distinctly help the 
cause of good architecture in America, and it 
deserves, and no doubt will have, a cordial 
welcome from the readers to whom it espe- 
cially appeals. It is easily the most interesting 
and most helpful book of its kind that has 
appeared for some years. 
Forest TREES OF THE PaciFic SLOPE. By 
George Sudworth, Forest Service, U. S. 
Department of Agriculture. Washing- 
ton: Government Office. Pp. 441. 
This important book is the first of four 
which are to deal with all the native forest 
trees of North America north of the Mexican 
boundary. The region treated includes 
Alaska, British Columbia, Washington, Ore- 
gon and California. It thus contains an 
account of the tree species known to inhabit 
the Pacific region, numbering a hundred and 
fifty in all. An extended subject is thus com- 
pressed within very reasonable compass. The 
descriptions and information concerning the 
trees are concisely given, and the value of the 
book is enhanced with numerous illustrations. 
STRUCTURAL DETAILS, OR ELEMENTS OF 
DersicN IN HEAvy FRAMING. By 
Henry S. Jacoby. New York: John 
Wiley & Sons. Pp. 9+368. Price, 
$2.25 net. 
The title of this volume corresponds to a 
course of instruction conducted by the author 
in the College of Civil Engineering in Cornell 
University during the past nineteen years. In 
this course the students receive their first in- 
struction in the application of the principles 
of mechanics to the design of the details of 
structures. Experience has shown that in 
many respects problems involving timber con- 
struction are better adapted for this purpose 
than if confined to structural steel. 
If it may appear at first as if too much at- 
tention to details is given in the examples on 
the design of joints, beams and trusses, the 
author believes that the importance of careful 
study of every detail can only thus be properly 
emphasized. In practise it seems to be the 
exception rather than the rule to give the 
same attention to details of timber structures 
as to those of steel. In the interest of sound 
engineering practise it is essential that all 
connections and details have the same degree 
of security as the framed members. 
In several articles the order of design is 
given in full, with a view of economizing the 
time of the student, and of promoting system- 
atic habits in making the computations re- 
quired, these objects being mnegarded as 
important elements in efficient engineering 
education and practise. 
The volume is published in handsome form, 
and is amply illustrated with diagrams, 
sketches and views.
