followed by obedient response at the second whistle, 
caused a shiver of real amazement among the spectators. 
John Hays Hammond, Jr., has 600 patents on orig- 
inal inventions that he has perfected since he began his 
experimental work at Gloucester a few years ago. For 
sone time his experiments have been thought important 
enough for the government to watch closely and army 
electrical experts are among the regular workers at the 
Hammond laboratory. With these, as an aid, is a ser- 
geant in the regular army, and from time to time the 
Navy Board sends other officials to investigate different 
experiments undertaken by Mr. Hammond. Apparatus 
is also loaned from Washington and little by little the 
work has grown of such interest to the war board that 
today the daily work within the walls of the laboratory 
is as much a secret as would be maintained at one of the 
different naval experiment stations. 
However, Mr. Hammond still has the direction of 
all undertakings that go on here and is regarded by the 
war officials as an authority in electrical work. 
Just now the wireless house-boat is the chief object 
of interest to both Mr. Hammond and the government 
aids. Imagine a fifty-foot craft a little wider than the 
ordinary small yacht, one that bulks up too much for any- 
thing like high speed, but an altogether safe and sane 
boat, equipped with wireless antennae, strung fore and 
aft to receive the radio pulsations which emenate from 
the station on shore. Below in the cabin of this little 
craft there is a small case, say the size of the cedar chest 
in the attic at home, where the winter furs are packed. 
This contains the machinery—this case with its tiny 
switchboard at one end and its coils, batteries and me- 
chanis™s connected with the antennae overhead. 
This, the steering gear and the motor that whines 
and hums when the boat begins to move, constitute the 
directing and motive power of the houseboat. A similar 
equipment would give life to a torpedo sent at a 33-mile 
clip just under the surface of the water toward a hostile 
NORTH SHORE BREE Z Band “Reminder 
battleship. ; 
There are two classifications under which the opera- 
tion of such a wireless wave driven boat or torpedo comes: 
the “polypulse” method, that is, a number of differing 
impulses each of which operate a particular impulse at 
the receiving apparatus, and the “monopulse” method, 
whereby a single kind of an impulse sent out operates and 
controls any single’mechanism, or all of them. Mr. Ham- 
mond’s method of operating a wireless boat falls into the 
last class. It is as if a clock were fitted with a hand 
which, if operated from a distance, could be made to stop 
on any hour or minute, the hand needing to pause, say 
two seconds before the energy would be exerted. 
Before Mr. Hammond invented a method of effect- — 
ually preventing the antagonistic wireless waves from in- — 
terfering with a from-the-land driven boat or torpedo, it 
was believed by government officials that his success in — 
giving high speed to such a craft would go a long way 
toward solving the problem of coast defence. 
For with a torpedo driving at a rate of 33 miles an 
hour through the water, even though a battleship should 
see such a weapon of destruction approaching, there would 
not be time to get inside the torpedo’s control before it — 
had reached its mark, since it would require nearly thirty 
minutes to find the right wave length to stop the torpedo. 
Recently Mr. Hammond has been carrying on tests to 
aid in rendering invisible to an enemy the part of a tor- 
pedo out of water when the projectile is speeding toward 
it’s mark. 
Very soon he is to take up work with a hydro-aero- 
plane, that is, an air ship which starts from the water 
and flies in the air. 
a water craft from a fixed station will be applied to the 
operation of an aeroplane which will start, rise and go 
through air manoeuvers directed by the operations of the 
wireless wizard at his keyboard in the laboratory as 
smoothly as if guided by the hand and brain of a steers- 
man on board. 
N AVALANCHE of trot experts and sympathizers 
descended on Magnolia last Friday afternoon for 
the last message of the summer in professional varieties 
of the walk-trot-and-canter gaits that have been success- 
fully put to ragtime. Rosita Mantilla and her partner, 
Mr. Floyd, have figuratively taken the blue ribbon in the 
walk trot and tango classes, but—the metamorphosis of 
the dance is by no means a professional attainment only —- 
pot at all! Many a debutante and college man have 
eequired skill enough for the boards. The assemblage 
last Friday was fascinating and smart enough to have 
done credit to the wost important North Shore hostess. 
Those entertaining were Mrs, Henry W. Estabrook, four 
euests; Mrs. E. M. Binney of Boston entertained Mrs. 
William Appleton; Mrs. Godfrey Ryder of Malden, four 
suests; Mrs, W. C. White, of Lowell, eight; Miss Cara- 
line Merral of New York, four; Miss Margaret Riker, 
two; Mrs. C. H. Callery of Pittsburg, five; Mrs. A. B. 
Dewey of Chicago, six; Mrs. J. K. Shaw of Baltimore, 
four; Miss Marie Dallet of Philadelphia, two; Mrs. W. 
F. Williamson of Quincy, Ill, seven; Mrs. W. F. Gam- 
ase of Gloucester. four; Miss Julia Culbert of New 
Vork, three; Mrs. Drake Mandeville of New York, four; 
Mrs, Charles Gately of Atlanta, five; Mrs. Somerset R. 
Waters of Washington, five; Mrs. Alfred Potter of Chi- 
cago, three; Mrs. George Wallace of Beverly Farms, six; 
Mrs..E. B. Richardson of Magnolia, four; Mrs. Phil- 
ly Longlev. nine; Mrs. Leonard C. Hanna of Manches- 
ter, six; Mrs. Samuel Culbertson of Manchester, six; 
Mrs. George FE. Carter of Brookline, eight; Mrs. Albert 
Bierstadt of New York, six; Mrs. H. M. Ranney of 
Brookline, four; Miss Charlotte Lane of New York, six; 
Miss M. FE, Patterson of Boston, six; Miss Marion Jones 
of Philadelphia, six; Mrs. J. A. Lee of Philadelphia, 
four; Mrs. David Loring of Boston, four; Miss Elsie 
Martin of Plainfield, N. J., four; Mrs. M. R. Wendell, 
Jr., of Jamaica Plain, who entertained eight.

A misguided maple leaf or two’has no influence at~ 
the Swimming Pool. When society wants to be enter- 
tained it pays no attention to the call of the calendar or 
to the omens of the season. The tennis tournament is 
one of the reasons for the balcony crowds and the pool 
is the other important reason. Not to mention the bridge 
tables that have found their way into the open, and the 
prevalent dansant mode for Saturday afternoons. It has 
been a truly great summer in Magnolia. Someone was 
heard to say, “There has been everything but a bull 
fight.”

“To succeed in life and in politics,” explains a writer 
in the Gaulois, ‘fone néeds to be dull, fat-mitted, without 
charm, ungrateful, and a monomaniac on the subject of 
one’s own prosperity.” However there are exceptions to 
all rules. Some get along in spite of everything. Look 
for y° “ROSE TREE” sign, Old Ipswich Village, near 
y° Rowley line. One often finds small parties of ex- 
ceptions lunching, having tea or supper. Tel. Rowley 1-6, 
if y° be more than four in number.
