What reading level is The Northern Barrage And Other Mining Activities book?
To quickly assess the difficulty of the text, read a short excerpt:
He was recognized to be a German by the type of the life preserver he wore. Since no engagements with the enemy had occurred within miles of this position, it is extremely probable that an enemy sub- marine had been destroyed by one of the mines which had been laid on September 7.
The reduction of premature explosions on this excursion was a marked improvement, being between 5 and 6 per cent, as compared with 13 per cent on the previous operation. The firing devices had been adjusted to operate... between 30 and 45 millivolts, and this regulation could not readily be increased on account of the construc- tion of the mechanism. It was perhaps as well that it should not be further raised as the mine might be possibly made too insensitive to operate when a poor contact was made by the antennae.
After completing the ninth excursion, work was resumed in Area "A. " On September 27, 5, 450 mines were laid, slightly over 4 per cent of which exploded prematurely. Only nine of the mine layers took part in this operation.
