.He hang the chandelier, containing many 51_________

Thus he warned passing ship from the danger 52________
along the coast.
Candles soon became the common fuel for signal lights.
They were later replaced by oil lamps,
that could burn longer and brighter. Kerosene and 53_________
gas lamps also tried .These are still in use now in 54_________
some smaller lighthouses. But today most lighthouses
sent electric light blazing out over the sea. 55_________

Keep off !”But the modern lighthouse also
identifies it in a code known to all shipping .Most of 56_________
the great lights have their own special signals. The
light may be one that blinks—as a giant firefly in the 57_________
night .Or it may be a revolved light that is red and 58_________
then green. Or it may be only white .But however 59__________

range is never at a loss to know which lighthouse it
is , and where it is being located . 60__________
