Starting the Garden 
in Early March 
YOU know the possibilities of hotbeds — a chance to start growing un- 
der glass, even while the snow is on the ground. To transplant 
later and have blooming flowers and luscious vegetables, on your table 
or ready for the markets, many weeks in advance of those gardens 
which wait for the “safe” period of planting in the open. 
Easy-to-Buy 
Or you can start a little later with 
glass covered coldframes — elim- 
inating the heat generating 
sub-bed of manure which is 
needed when the start is made 
in late February or early March. 
In either case, you'll be most suc- 
cessful if you use DUO GLAZED 
SASH — the sash with two layers 
of glass and insulating air space 
between — the sash that, being 
frost-proof, needs no night cover- 
ings — the sash of greatest service 
because built to last and designed 
for easy glazing. 
With a LITTLE 
GEM GREENHOUSE 
— the luxury, heated garden frame — you 
can have produce and posies, the whole 
year through. This Duo Glazed F rame 
giving forty square feet of growing space, 
is furnished complete with heater and sub- 
frame at a cost of only £49.50 
A WORD ABOUT 
DUO GLAZED SASH 
Constructed from Louisiana Red Cypress — 
a wood that longest defies decay. The 
members, joining, design, and method of 
utting together are the utmost effort of a 
ig sash factory backed by the resolution 
to build as well as is humanly possible 
The improved method of glazing is so sim- 
ple. so free from complications, that you 
would not be satisfied with any othertype, 
once you know Duo Glazed. 
They need no night coverings or shutters. 
The dead air space between the closely fit- 
ing glass gives not only frost-proof protec- 
tion but allows the warmth from the sun to 
enter and be retained. 
In 3ft. by 6ft. size they cost less than $1.84 
each — in lots of two dozens (slightly less 
or more for other quantities). Also sold 
with Hotbeds and Coldframe Outfits, in 
Garden frames and in 
Greenhouses. 
DUO GLAZED GREENHOUSES 
are built and shipped in section- 
al units painted and with glass 
furnished for as low as $138 in 
the sunken path, 10ft. by 12ft. 
size. Lean-to types at $90 and 
up according to size and style 
(beating systems not included 
at prices quoted). 
Duo Glazed Greenhouses, in a 
wide choice of models and sizes, 
are splendid in appearance, 
strong, low in cost, easy to erect, 
and because of the perfect insu- 
lation afforded by the Duo Glazed Sash 
and by the wall construction are econom- 
ical to heat and maintain.

T HERE is no flower that is so easijy grown and blooms so readily as 
THE GLADIOLUS, and by repeated plantings, a continued bloom 
may be had all summer long. The long spikes are graceful and fas- 
cinating in their great array of colors; cut as first flower opens and placed 
in water, the flowers develop for a week, even to the last bud. 
GLADIOLI require no nursing, spraying or other special attention. 
Once planted the bulbs take care of themselves asking no favors and 
making no demands, but adapt themselves to the best conditions avail- 
able. Commence planting in April and repeat at io day intervals until 
the end of June, and you will have flowers until late autumn.

How much land would I need and what kind of 
a house for the raising of lettuce, flowers, etc.? 
Wouldn’t it be best to buy about three acres of 
land not very far from a city, with perhaps a 
house and barn, and build my own greenhouse? 
—A. W„ Ohio. 
— The greenhouse business may prove a very 
profitable one when well managed, although it 
involves various business risks and the need of 
training and knowledge the same as any other 
branch of farming or, for that matter, any 
other business. If you like plants and flowers 
and feel sure that you are fitted for the business 
and could put into it the energy and en- 
thusiasm that any one must put in any voca- 
tion in which he is to succeed, it would be a 
good one for you to take up. Your plan of 
buying land and building a greenhouse is all 
right for any one that has had practical ex- 
perience and who has enough money to keep 
going until he is established and returns begin 
to come in; but for any one situated as you 
appear to be, it would be far better to look for 
work in some already successful greenhouse 
where the practical details of the business can 
be learned gradually and thoroughly. Prob- 
ably one of the best things you can do is to go 
to your Agricultural College and talk to the 
Professor of Horticulture there. He can un- 
doubtedly give you valuable advice and sug- 
gestions. Prof. White’s book “Principles of 
Floriculture” is a book you should read care- 
fully before proceeding further. Its price is 
$1.7$. 
To Correctly Set a Sundial 
** What is the correct way to set a sundial? — 
C. H. M., N. Y. 
— A sundial is useless as a time keeper unless 
the gnomon is properly pointed. This cannot 
be done properly by the variable compass. The 
best way to get the gnomon properly pointed is 
to obtain from an almanac the date at which 
the pole star .will be at the meridian, and point 
the gnomon that night. To do this, adjust 
the poles in a line with the star, and sight along 
the north-south line of the dial and these two 
poles. The twelve o’clock point should be due 
north. The disk of the horizontal dial must 
always be exactly level and the gnomon per- 
pendicular to it. 
What to Use to Make a Fertilizer 
What is the proper proportion of wood 
ashes, hydrated lime, sheep (or any other) 
manure, phosphate, bone meal, to use in order 
to have a first class fertilizer and worm de- 
stroyer for use on lawn, flower beds, and potted 
plants? Is powdered sulphur good? — N. C. 
P., Mo. 
— It would be extremely unwise to make a 
fertilizer mixture of lime or wood ashes and 
any form of organic manure such as sheep 
manure, since such a mixture results in the 
wasting of much of the nitrogen. Your best 
plan will be to use the lime and wood ashes by 
themselves at the rate of perhaps 1, 000 pounds 
per acre, working it well into the newly dug or 
plowed soil. Then you can add a dressing of 
the sheep manure, as much as 1,000 pounds 
per acre being safe, this to be well harrowed 
in. Acid phosphate, if desired, can also be 
applied at the same time, 500 or 600 pounds 
being a great plenty. Bone meal is an excel- 
lent potash and phosphoric acid fertilizer, and 
can be used generously in any soil or compost 
for indoor or outdoor work. Sulphur is not 
a fertilizer but is useful in fighting rusts, mil- 
dews and other fungous diseases.
