ADDITIONAL REPORT OF THE COMMITTEE ON LIGHTS.

WASHINGTON, December 12, 1889. To Rear-Admiral S. R. FRANKLIN, U. S. Navy,

President of the International Marine Conference, etc.: SIR: In accordance with the resolution passed by the Conference on the 9th instant, your committee have again considered the question whether it would be advisable to assign a certain position to the side lights, as has been done by extra amendment No. 41 to Article 3, which has led to the rule adopted by the Conference, viz:

“The said green and red side lights to be placed in steam.vessels not forward of the mast-head light and in sailing vessels as near abreast the foremast as practicable."

Doubts have been raised by the Collocation Committee on the advis. ability of this rule on the ground that it involves a radical change and leads to great expense by compelling a very material alteration of the present construction of many ships, consequences which are said to outweigh the slight advantage of the introduction of the rule in question.

Your committee, after having most carefully considered the subject, are unanimous in reporting that in their opinion the rule passed by the Conference ought to be maintained.

In the report dated November 4, 1889, the reasons have been given why in principle it would be advisable to have the side lights of all steam. vessels so placed that a vertical plane through the line drawn from them to the mast-head light would form a certain kuown angle with the keel. It has at the same time been acknowledged to be practically impossible to give the side lights a certain fixed position in regard to the foremast light, but it has been thought practicable and therefore bas been recommended to introduce a rule by which steamers are compelled to carry the side lights abaft the foremast light, the counecting line forming an angle of six points with the keel, or as nearly so as possible.

The considerations which have led to this recommendation appear to your committee to be sound, and whilst confirming what has been said in the former report we beg to add the following remarks:

The rule as adopted by the Conference does not, it is true, go quite so far in assigning to the side lights a certain fixed position with regard to the mast-head lights as the recommendation contained in our report

[ocr errors][ocr errors]

of the 4th of November. Nevertheless, by preventing steam-vessels from carrying the side lights forward of the mast-head light, it will serve to give more certainty to the respective position of the regulation lights, and thus, in our opinion, will mark a decided improvement of the means of ascertaining the course of an approaching steamer, which improvement will gradually be increased when experience shows the advantages of the system.

On the other hand, the difficulties connected with the introduction of the rule appear to be not at all insurmountable. Many ships are even now constructed so as not to require any changes in consequence of the adoption of this rule. Others might easily comply with the rule by changing the position of the mast-bead light in placing it more forward of the foremast. And even if the position of the sidle lights should have to be altered, this could in most cases be done without incurring too heavy expense.

We therefore recommend to let the rule stand as it is, provided, however, that the rule be adopted universally. Having regard to the difficulties which some ship-owners may justly feel if they had to comply with the new rule at once, your committee think that sufficient time should be allowed for the effecting of the changes necessitated by the rule, so as to enable ship-owners to carry out these changes under the most convenient conditions. Vessels now in course of construction will, of course, be able to adopt the new principle at once.

As regards sailing vessels, the committee do not consider it necessary to adopt the above-mentioned rule. We have the honor to be, sir, your most obedient servants,
