log line w as one hundred and in length and was wound on a which turned very easily so that the resistance of the to the water would it the log line is divided into certain spaces called knots the length of each of which is the same part of a mile that a half minute is of an hour if there be sixty one hundred and twenty feet in a mile or the part of a degree of a great circle which is not far from accurate and the ship be going ten knots an hour she will run sixty one thousand two hundred feet in an hour if the were thrown overboard at eight o clock and the line were long enough the ship would have run out thousand two hundred feet or ten miles at nine o clock or in one hour in one minute she would run one of sixty one thousand two hundred feet which is ten hundred and twenty feet in half a minute five hundred and ten feet the half minute glass is the measure of time generally used in heaving the log while the sand is dropping through the line runs out five hundred and ten feet the ship going ten knots an hour being the basis of the calculation one knot therefore will be one feet if the line pays out five hundred and ten feet in thirty seconds by the glass the ship is going ten knots an hour if it pays out four hundred outward bound or and eight feet in half a minute or eight hundred and sixteen feet in a minute she will pay out a mile in as many minutes as eight hundred and sixteen feet is contained in sixty one hundred and twenty feet which is seven and a half minutes then the ship goes a mile in seven and a half minutes or eight miles an hour a knot on the log line is therefore invariably feet and the number of knots of the line run out in half a minute also the ship s speed per hour for fifty one feet is the same part of a mile that half a minute is of an hour the calculations are given without merely to show the principle and both the glass and the line are modified in practice on board the young america ten were allowed for stray line this length of line being permitted to run out before the measuring commenced in order to get the clear of the in the wake of the ship the ten were indicated by a white rag drawn through the line and when the officer paying out comes to this mark he orders the to turn the glass and the operation actually begins at every fifty one feet or and six making the there is a mark � a bit of leather or two or more knots the instant the sands have all run through the glass the says up and the officer notes the mark to which the line has run out half and quarter knots are indicated on the line now mind your eye when the officer of the deck says turn you repeat the word young america afloat after him to show that you are alive continued peaks ready said ready replied smith the lieutenant threw the into the water and when the stray line had run off he gave the word to turn the glass turn repeated smith off the log line so that nothing should prevent it from running easily up shouted smith and stopped the line very well added peaks what s the mark ten and a quarter replied the officer that sounds more like it i knew this ship was going more than seven knots you see young gentlemen you can t catch flies and tend the line at the same time now you may try it over again the experiment was repeated with the same suit other officers and were called to the quarter deck and the training in heaving the log continued until a reasonable degree of was attained land ho cried the on tlie top gallant at about eleven o clock in the where away called the officer of the deck dead ahead sir what is that land mr asked paul don t j ou know � i m sure i don t outward bound or then you should study your more look at the compass and tell me how she heads south east sir replied paul after looking into the now what land lies south cast of harbor asked tlie principal cape i think you are right then that must be cape is it really certainly it is laughed mr have you no faith in your map i didn t think we could be anywhere near cape i thought it was farther off added paul who seemed to be amazed to think they had actually crossed bay the land you see is race point which is about forty miles from the entrance to the bay at the head of which is we have been making about ten knots an hour and our calculations seem to be very accurate by one o clock we shall come to anchor in harbor this was fully and the young america was off the town those who had been recovered as soon as the motion of the ship ceased and when everything aloft and on deck had been made snug the crew were to dinner in tlie afternoon part of the students were permitted to go on shore the band played and several boat races took place very much to the delight of the people on shore as well as those on board at six o clock the ship was opened for the reception of visitors who came off in large numbers to inspect young america afloat the vessel after dark there was a brilliant display of and the young america
