and direction of the Board of Trade. The Board of Trade will confine themselves strictly to the function of giving such advice and direction as may be necessary for procuring the proper execution of the works required by the Colonial Authorities, but they will not open a *} account, or make themselves responsible for any payments whatever. In giving instructions to the Agent, it must be understood by the Colonial Authorities, that as it will be necessary for the Board of Trade to employ an engineer and oth r professional men, their expenses are to be included with those of the works, and paid by the Agent accordingly. If it is the desire of the Colonial Authorities that the material should be shippe ! or forwarded by any particular vessel, special directions are to be given to the Agent, who should also be directed to effect jhe necessary insurances, should they be determined upon. As considerable care in the management of Lighthouses and Light Vessels, and in the economy of the oil antl wicks, the cleanliness of the reflectors, burners, glasses. &c., is requisite, the directions which the Trinity House have issued for the guidance of their own Light Keepers are herewith annexed, that Colonial Authorities may have the advantage of their long experience, and adopt them in the management of the Colonial Lighthouses, if they should think fit; and as the Colonial Authorities may have occasion to construct Light Vessels, there are annexed to this Memorandum the dimensions of the Light Vessels used in this country, and all other particulars necessary for the building of such vessels, and for tendering for contracts to build them, and for their equipment and maintainance. Should it be necessary to apply to England for the lanterns and lighting apparatus, the dimensions given in the annexed paper will be strictly adhered to, so that the construction and fitting of the vessel may all go forward in the Colony, and the vessel be ready to receive the lanterns by the time they arrive.
