The Nature Lover for April begins hs follows : — ‘ It was towards the 
end of March that the Earth had, so to speak, turned herself broadside 
on to the Sun, whose vitalizing rays flooded the face of her from Pole 
to Pole. Everywhere day and night were of equal length, with the 
former gaining steadily, and now for six months the balance will be in 
favour of daylight. And to the warm, outpourings of the sun the whole 
world of living things is responding with outpourings of living green, 
of beauteous bloom, of bird song, and those varied manifestations of the 
emotions characteristic of that season of the year.’ There are notes 
also on the Wood Anemone ; Scent in Nature, I. — In the Plant World ; 
Swallow Birds ; and the Moon, all of which are illustrated.
