A large number of eggs is of some importance to those species, which depend on a rapidly fluctuating amount of food, for it allows them rapidly to increase in number.
In looking at Nature, it is most necessary to keep the foregoing considerations always in mind--never to forget that every single organic being around us may be said to be striving to the utmost to increase in numbers; that each lives by a struggle at some period of its life; that heavy destruction inevitably falls either on the young or old, during each generation or at recurrent intervals.
What checks the natural tendency of each species to increase in number is most obscure.
But this is a very false view: we forget that each species, even where it most abounds, is constantly suffering enormous destruction at some period of its life, from enemies or from competitors for the same place and food; and if these enemies or competitors be in the least degree favoured by any slight change of climate, they will increase in numbers, and, as each area is already fully stocked with inhabitants, the other species will decrease.
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.
Hence, if certain insectivorous birds (whose numbers are probably regulated by hawks or beasts of prey) were to increase in Paraguay, the flies would decrease--then cattle and horses would become feral, and this would certainly greatly alter (as indeed I have observed in parts of South America) the vegetation: this again would largely affect the insects; and this, as we just have seen in Staffordshire, the insectivorous birds, and so onwards in ever-increasing circles of complexity.
The East-Indian and Chinese markets, the colonisation of America, trade with the colonies, the increase in
the means of exchange and in commodities generally, gave to commerce, to navigation, to industry, an impulse
But now, thanks to the machine-civilization, China's means of subsistence had been enormously extended, and there were no famines; her population followed on the heels of the increase in the means of subsistence.
At 5,000,000 a year increase, her total increase in the intervening seventy years must be 350,000,000.
As blind Nalasu slowly plodded away, with one hand tapping the path before him and with the other carrying Jerry head-downward suspended by his tied legs, Jerry heard a sudden increase in
the wild howling of the dogs as the killing began and they realized that death was upon them.
numbers is obviously impossible, and must be checked by some means.
But a wise ordinance of Nature has decreed that, in proportion as the working-classes increase in
intelligence, knowledge, and all virtue, in that same proportion their acute angle (which makes them physically terrible) shall increase also and approximate to the comparatively harmless angle of the Equilateral Triangle.
I will consent to share this dreadful secret with you, but I will not allow shame and remorse to grow and increase in
my conscience, as crime and misery will in your house.
The increase in
the younger generation of children who could not read nor write was perilous.
If the chumo is pleased with the treat and present, he will give him a declaration or writing to witness that his ground, which afforded five or six sacks of corn, did you yield so many bushels, and even of this it is the custom to abate something; so that our revenue did not increase in
proportion to our lands; and we found ourselves often obliged to buy corn, which, indeed, is not dear, for in fruitful years forty or fifty measures, weighing each about twenty-two pounds, may be purchased for a crown.
