A. _Vapour_ is a conductor, and therefore, may determine the shock; especially when connected with so many living bodies. Q. _Why is a THEATRE dangerous, during a thunder-storm?_ A. Because the _crowd assembled_ there, and the _great vapour_ arising from so many living bodies, render a theatre an _excellent conductor of lightning_. Q. _Why is a_ FLOCK _of sheep in greater danger than a smaller number?_ A. Because _each_ sheep is a _conductor_ of lightning, and the _greater the number_, the _better its conducting power_; besides, the _vapour_ arising from a flock of sheep _increases its conducting power_, and its danger. Q. _Why is a HERD of cattle in danger during a storm?_ A. 1st--The _number_ of living bodies increases the conducting power of the _animal fluids_: and 2ndly--The _vapour_ arising from a herd is also a good conductor. Q. _If a person be ABROAD in a thunder-storm, what place is the SAFEST?_ A. Any spot about 20 or 30 feet from some tall tree or building; unless that spot be near to running water. Q. _Why would it be safe to stand 20 or 30 feet from some tall tree, in a thunder-storm?_ A. Because the lightning would always choose the _tall tree_ as a conductor, rather than the _shorter man_; and he would not be sufficiently near the tree, to be injured by the electric current passing down it. Q. _If a person be in A CARRIAGE in a thunder-storm, in what way can he travel most SAFELY?_ A. He should not lean _against_ the carriage; but sit upright, without touching any of the four sides. Q. _Why should not a person lean AGAINST the carriage in a storm?_ A. Because the electric fluid might run down the sides of the carriage; and (if a person were leaning against the sides), would make choice of _him_ for a conductor, and perhaps destroy life. Q. _If a person be in A HOUSE during a thunder storm, what place is SAFEST?_ A. Any room in the _middle story_. The _middle_ of the room is best; especially if you place yourself on a mattrass, bed, or hearth-rug. Q. _Why is the MIDDLE STORY of a house SAFEST in a thunder-storm?_ A. Because (even if the fluid _struck_ the house), its strength would be exhausted before it reached the middle story. Q. _Why is the MIDDLE of the ROOM more SAFE, than any other part of it, in a thunder-storm?_ A. Because, if the lightning came into the room at all, it would come down the _chimney_ or _walls_ of the room; and therefore, the further distant from these, the better. Q. _Why is a MATTRASS BED, or HEARTH-RUG a good security against injury from lightning?_ A. Because they are all _non-conductors_; and, as lightning always takes in its course the _best_ conductors, it would not select such things as these. Q. _Is it better to be WET or dry during a storm?_ A. To be _wet_: if a person be in the open field, the best thing he can do, is to stand about 20 feet from some tree, and get _completely drenched to the skin_. Q. _Why is it better to be WET than dry?_
