an entry must be made in tbe receiver’s office, who is authorized to extend the same, if he sees 
reasonable grounds for so doing-.

amount of which is determined by the regular tonnage of the boat. Any brick, stones, or sand, 
remaining on the quays more than one day, will be charged double quayage. No lime is permitted 
to be discharged on the quays, but must be put into carts out of the boat, and drawn away. 
Port Dues —By the authority of the 30th George the 3d, c. 31, the corporation collected 
the following port dues, which are only one-half of what they are entitled to by the act:— 
per ton. 
Coasters, ..... l-i d. ) 
Colliers, . . . . . 1 > Irish currency. 
British vessels from foreign parts, . . I-J. ^ 
Steamers are charged at a rate ^ lower, with tbe view of encouraging them. 
Patent Slip Dock .—Until about 5 years ago there was no accommodation for repairing vessels, 
except by laying them on the bank of the river, or excavating for them shallow docks or cuts in 
the sandy slob, a system, which, in spite of its difficulties, with so small a fall of tide, is still some¬ 
times followed : most vessels, however, were sent to Liverpool, or the Clyde, when in need of 
repair. In 1 830, Messrs. Pitt Skipton, and Co. undertook to construct a patent slip dock, where 
vessels of 300 tons register can now be hove out of the water, and repaired. The expense was 
£4000. 
In 1834 31 'vessels of all sizes were repaired at the slip, and it is found to answer all the 
purposes of a dry dock. 
Mr. Skipton’s partner is Mr. Henderson—an experienced lieutenant in tbe navy: a first-rate 
foreman, and a gang of good shipwrights, are employed in the general yard attached to the esta¬ 
blishment, from which a vessel of 180 tons register has recently been launched. It is a 
handsome vessel, built of Irish oak, and calculated to carry 259 tons. 
For masts American pine is most approved, for spars Baltic, but American is generally used. 
Irish timber, chiefly oak, is procured from Walworth wood, Killymoon, Beach Hill, Learmont, &c. 
Irish timber is more used than English. 
Miscellaneous Observations .—The port is well supplied with naval stores from Belfast; but 
sails, &c. are manufactured on the spot. 
Small vessels, when outward bound, water at the wharfs, but large vessels at Moville, to 
ensure a light draft in crossing the flats which lie between Derry and that place. 
The people of the neighbourhood engage readily in maritime pursuits. 
Internal Trade .—The first impulse of the growth of a seaport must be given by the neces¬ 
sity of providing external markets for the increasing produce of well cultivated rural districts, or of 
extensive manufactories. Without the advantage of such sources of supply, the most favourable 
natural position must prove insufficient to advance a port to eminence ; and the neglect of this 
consideration has often led to projects, which have only resulted in wasteful expenditure and useless 
establishments. 
In Derry many of these advantages are found to exist in a very high degree; it is, in short, 
the natural port of export for the rural productions of a large space of fertile country, which 
extends far into the counties of Donegal and Tyrone, and is still the market for a considerable 
quantity of linen. Nor can there be a doubt, that from the future improvement of internal com¬ 
munications, a new extension of external trade may be expected, and a general enlargement of all 
the commercial relations of the port.
