of the project. The concrete will be one 
part Portland cement, three parts of fine 
sand and five parts of broken stone and 
gravel that will pass through a one-half- 
inch mesh. To prevent the separation 
of the different parts of the concrete and 
to add to its uniform flow it is proposed 
to add to the mixture colloids of electro¬ 
lytes in small quantity. Color may be 
added to the concrete, but the cost of 
this was not estimated in the original 
cost of the structure; but either that or 
the application of color on the exterior 
would be demanded. It is plain that to 
overcome the law of gravity in the settle¬ 
ment of the heavier particles of the con¬ 
crete is an important matter. Perhaps 
the use of compressed air, which is used 
to the amount of loo pounds per square 
inch, and which is used in the applica¬ 
tion of cement grouting in repairing 
dilapidated masonry and in filling the 
cracks of walls in England, might be 
successful. 
The concrete is carried to the top of 
the building by means of a bucket 
elevator. It will require the discharge 
of eighteen buckets of a capacity of one- 
half cubic foot each to carry up 200 
cubic yards per ten hours. The public 
await more information on this matter 
before deciding as to the merits of Mr. 
Edison’s project .—The Western Archi¬ 
tect and Builder. 
THE VERY NEWEST IDEA IN LIFE 
INSURANCE 
ERE is something really “ dif¬ 
ferent.” Just think of a life 
insurance policy which enables you to 
leave to your wife a monthly income—a 
guaranteed sum which nothing can 
disturb, not affected by hard times, bad 
judgment in investments—which cannot 
be lost, depreciated or stolen, but which 
will come to her regularly every month 
for twenty years or for her lifetime if you 
want it so. Enabling her to adjust and 
meet the family expenditures, relieving 
her from all worry and putting poverty 
out of reach. 
This is exactly what is accomplished 
by the new monthly income policy just 
issued by The Prudential Insurance 
Company, the very latest development of 
modern life insurance. 
The demand for a policy of this kind 
must needs be great for it relieves the 
wife and mother of the responsibilities of 
securing a safe and profitable investment
