A. Because the higher regions of the air are _laden with vapour_, on the very _point of condensation_, which the rising sun cannot disperse. Hence our Lord's observation, "In the morning (ye say) it will be foul weather to-day, for the sky is red and lowering." (Matt. xvi. 3.) Q. _Why is a GREY MORNING an indication of a FINE DAY?_ A. Because _that_ air alone _contiguous to the earth_ is damp and full of vapour. There are no vapours in the _higher_ regions of the air _to reflect red rays_; and hence the morning-light looks grey. Q. _What difference (in the state of the air) is required, to make a GREY and RED SUNRISE?_ A. In a _grey_ sunrise, only that portion of air _contiguous to the earth is filled with vapour_; all the rest is clear and dry. But in a _red_ sunrise the air in the _upper regions_ is so full of vapour that the rising sun cannot disperse it. Q. _Why is a GREY SUNSET an indication of WET?_ A. If the air on the _surface of the earth_ be very _damp at sunset_, it is a proof that the air is _saturated with vapour_, and wet may be expected: hence the proverb-- "Evening red and morning grey Will set the traveller on his way; But evening grey and morning red Will bring down rain upon his head." Q. _The proverb says, "A RAINBOW in the MORNING is the shepherd's WARNING:" why is it so?_ A. A rainbow can only be formed _when the clouds_ (containing or dropping rain) _are opposite the sun_: a _morning_ rainbow, therefore, is _always in the west_, and indicates that bad weather is _on the road to us_. Q. _Why does a RAINBOW in the WEST indicate that BAD WEATHER is on the road to us?_ A. Because our heavy rains are usually _brought by west or south-west winds_; and, therefore, clouds which reflect the colour of the rainbow _in the west_, are coming up _with the wind_, bringing rain with them. Q. _The proverb says, "A RAINBOW at NIGHT, is the shepherd's DELIGHT;" why is it so?_ A. As a rainbow is always _opposite to the sun_, therefore a rainbow at _night_ is in the _east_, and indicates that bad weather is _leaving us_. Q. _Why does a RAINBOW in the EAST indicate that bad weather is LEAVING us?_ A. As _west_ and _south-west_ winds bring _rain_, if the clouds have been driven _from the west to the east_, they have passed _over us_, and are going _away from us_. Q. _What is meant by an AURORA BOREA'LIS, or northern light?_ A. A _luminous white cloud_ in the _north of the sky_ at night-time. Sometimes streaks of blue, purple, and red,--and sometimes flashes of light, are seen also. In our island this phenomenon generally rises from a dark cloud (running from the north to the east and west) elevated about 10 or 20 degrees above the horizon: above this dark bed of clouds the luminous white light appears. Q. _What is the CAUSE of the AURORA BOREALIS, or northern light?_ A. _Electricity_ in the clouds. Q. _Why is the AURORA BOREALIS generally a WHITE light?_
