5.30 P. M.—Messages were received from both H. M. S. battle-cruisers
_Tiger_ and _Renown_, which had been previously sent by the Admiralty
out into the Atlantic to assist us with weather-reports and general
observation. They reported respectively as follows:
H. M. S. _Tiger_.—“Position 36 degrees 50 minutes north, 36 degrees 50
minutes west, 1,027 millibars, falling slowly, thick fog.”
H. M. S. _Renown_.—“Position 60 degrees north, 25 west, 1,027
millibars, falling slowly, cloudy, visibility four miles.”
Harris’s deductions from these reports were to the effect that there
was no steep gradient, and that therefore there was no likelihood of
any strong wind in that part of the Atlantic.
SET CLOCK BACK HALF-HOUR
6 P. M.—Scott increases height to 2,000 feet, and at this height we
find ourselves well over the clouds and with a bright-blue sky above
us. The view is an enchanting one—as far as one can see a vast ocean
of white fleecy clouds, ending in the most perfect cloud horizons.
Two particularly fine specimens of windy cirrus clouds, of which
Pritchard promptly obtained photographs, appear on our port beam, also
some “cirrus ventosus” clouds (little curly clouds like a blackcock’s
tail-feathers), all of which Harris interprets as a first indication
and infallible sign of a depression coming up from the south.
We hope that this depression, when it comes, may help us, provided we
have crossed its path before it reaches us. If we can do this we may
be helped along by the easterly wind on the northwesterly side of the
depression.
It is interesting to note that as yet we have received no notice of
this depression coming up from the south in any weather-reports.
6.40 P. M.—Put back clock one-half an hour to correct Greenwich mean
time. Time now 6.10 P. M. Position: Latitude 53 degrees 50 minutes
north; longitude 20 degrees west.
We have covered 610 sea-miles, measured in a direct line, in 17 hours,
at an average speed of 36 knots, or 40 miles per hour. Depth of
Atlantic at this point, 1,500 fathoms. At this rate, if all goes well
and if that depression from the south doesn’t interfere, we should see
St. John’s—if visible and not covered in fog as it usually is—about
midnight to-morrow, July 3.
6.55 P. M.—Wireless message from Air Ministry via Clifden states:
“Conditions unchanged in British Isles. Anti-cyclone persistent in
Eastern Atlantic—a new depression entering Atlantic from south.”
This confirms Harris’s forecast and is an admirable proof of the value
of cloud forecasting.
SEA AND SKY INVISIBLE
7 P. M.—The clouds have risen to our height and we are now driving
away through them with no signs of the sky above or the sea underneath.
Scott reckons the wind is northeast by east and helping us slightly.
Airship now very heavy owing to change in temperature and 12 degrees
down by the stern. Running on all five engines at 1,600 revolutions,
height 3,000 feet.
