The famous “Spec- 
jacks,” three■ times 
reported lost, noio 
safe at home after 
16 months’ voyage 
jlround the world 
with the Speejacks' 
T HE 35,000-mile cruise of this little 98-foot motor yacht was a 
thrilling exploit, replete with courage, daring, hardship and 
adventure. 
Lonely tropical islands of the South Seas, off the routes of trade 
—the East Indies, the Red Sea, the Mediterranean—the empty 
miles of the Atlantic, were covered by Commodore Gowen and 
his wife in a wonderful voyage of more than a year. 
The log of this amazing cruise was written, from start to finish, 
by Mrs. Gowen, on a 
Remington Portable 
Typewriter 
Here is Mrs. Gowen’s own story of how this sturdy machine performed: 
“One of the most useful necessities of our equipment for the ‘Speejacks’ was 
the Remington Portable Typewriter we purchased before leaving America. It 
stood the inclement weather, the torrid heat of the tropics and the frequent 
douchings of salt water without loss of efficiency. 
“I don’t suppose that any typewriter in existence ever had harder wear or 
went through a more stormy period than did this typewriter. 
“It is in as good condition today as the day we bought it. I am still using 
my Remington with a great appreciation of its endurance and efficiency.” 
The Remington Portable has the Standard four-row Keyboard. Fits in a case 
only four inches high. For sale by over 2500 dealers and

and passing of gusts, to arrange to 
make the exposure in the dead calm in¬ 
tervals. It is even possible to make an 
exposure in sections, opening the shut¬ 
ter when the plant comes to rest and 
closing it at the onset of the next period 
of movement, until the full exposure 
has been given. This method is feasible 
only if no bending or twisting of any 
object included in the field has been 
done, as in the latter case the part so 
changed is not likely to come back to 
the required position again, and suc¬ 
cessive exposures will show double or 
tiple images. Usually there is less 
wind before ten o’clock. 
In order to eliminate the wind nui¬ 
sance entirely it is best to carry a little 
tent of white silk, five feet high and 
five feet in diameter. Such a tent will 
fold up into a small bundle which goes 
easily into the pocket and which weighs 
but a few ounces. In use the tent is set 
up on a tripod of sticks, with other 
sticks leaning against the tripod so as 
to keep the walls of the tent out, over 
the plant to be photographed. The 
door of the tent should be on the lee 
side, and the camera is set up outside 
the tent with the lens in the doorway. 
This tent enables one to work in quite 
a stiff breeze, and while a plant under 
the tent requires double the exposure 
that it would need in the open, this does 
not matter as the plant is perfectly mo¬ 
tionless. Some plants are of course too 
large to permit of their being photo¬ 
graphed in the tent, and in dealing with 
such plants the photographer has the 
option of waiting for a calm day or of 
using fast shutter speeds and a large 
stop, in the latter case sacrificing depth 
of field. 
A plant should never be photographed 
in bright, direct sunlight, because of 
the heavy cast shadows, and because 
the delicate tone-gradations are lost. 
Here again the tent is useful, as it acts 
as a diffuser. 
In plant photography an exposure 
meter, or an exposure calculator, is in¬ 
dispensable, and having ascertained the 
exposure it is necessary to remember to 
allow for the bellows extension, as this 
is a factor which nearly always comes 
into play in this work. The rule is—the 
square of the focal length of the lens is 
to the square of the bellows extension as 
the normal exposure is to the required 
exposure. Thus, if we have a lens of 5 
ins. focal length, and we use it at an 
extension of 10 ins., and if the exposure 
with the lens focussed for infinity is 3 
second, we have— 
5 x 5 is to 10 x 10 as 3 is to 12 
and the required exposure is 12 seconds. 
The best plan it to work out the 
factor for each extra inch of bellows 
extension, to mark the position of the 
lens at each inch of extension on the 
bed of the camera, or on the trunions, 
and to carry this data in the field.
