Thus we can easily raise plenty of corn and rape-seed, &c., in our fields, because the seeds are in great excess compared with the number of birds which feed on them; nor can the birds, though having a superabundance of food at this one season, increase in number proportionally to the supply of seed, as their numbers are checked during winter: but any one who has tried, knows how troublesome it is to get seed from a few wheat or other such plants in a garden; I have in this case lost every single seed.
If then, as appears probable, species first become rare and then extinct -- if the too rapid increase of every species, even the most favoured, is steadily checked, as we must admit, though how and when it is hard to say -- and if we see, without the smallest surprise, though unable to assign the precise reason, one species abundant and another closely allied species rare in the same district -- why should we feel such great astonishment at the rarity being carried one step further to extinction?
Wilson was busy in the kitchen, but the room was not empty; and I scarcely checked an involuntary recoil as I entered it; for there sat Miss Wilson chattering with Eliza Millward.
