ACCESSIBILITY OF SHEDS.
367
The following are the records of actual dead-weight cargoes discharged at
Liverpool at the dates named : —
“ Georgie,” July, 1899. “ Cymric,” August, 1899. “Cymric,” October, 1900.
General cargo, . Bulk grain, . Fresh méat, Live stock, . Tons. Tons. 4,517 5,118 611 10,246 696 Tons. Tons. 5,084 4,665 612 10,361 575 Tons. Tons. 3,504 6,193 567 - 10,264 687
10,942 10,936 10,951
The diversity between weight and capacity is illustrated by the sample
cargoes given below :—
Name of Ship. Length. Gross Regis- tered Tonnage. Cargo. Area of Shed Occupied.
Tons Weight. Tons Measurement. Cubic Feet.
“ Horace,” Feet. 350 3,335 2,959 5,436 Sq. Yards.
“ Cymric,” 5854 12,647 9,749 13,390 535,600 18,647
£‘ Georgie,” 5584 10,077 9,209 11,112 444,480 18,647
“Celtic,” . . 6S1 20,880 6,102 15,644 625,760 18,647
One ton measurement is équivalent to 40 cubic feet of the ship’s hold occupied by
actual cargo. The ship’s gross registered tonnage is based on her total content, calculated
by certain rules and divided by 100.
The cargoes have been purposely chosen to exhibit a wide range and
contrast.
Accessibility of Sheds.—Under all these mutable conditions one thing,
at any rate, is perfectly clear—viz., that the means of access to a shed, and
the facilities for the transference and removal of its contents are points of
vital importance. It will be well then to briefly consider what steps may
be taken to achieve the ideal result.
Considérable divergency of opinion will be found to exist in regard to
this question at various ports, due mainly to conditions peculiarly local.
For there are no less than four ways in which oversea goods may be
despatched to their final destinations, and each of these obtains to a greater
extent than the others at some locality and demands special measures.
They are as follows : —
1. By direct transfer to coasting vessels, barges, lighters, and other
river and canal craft.
2. By direct transfer to railway trucks and waggons.
