A given species of plant may owe its existence to the selective adaptation of its flowers to insect fertilisers; but the character of its leaves may be the result of variations of an indifferent character. It is the origin of variations of this kind to which Darwin refers in his frequent reference to what he calls "laws of correlation of growth" or "correlated variation."
The growing of the same crops year after year upon the same fields, the neglect of precaution against the washing away of the soil surface, and the failure to use fertilisers, have made the profits of tillage disappointingly small. Billions of dollars have been lost by these communities through persistent soil exhaustion and erosion.
With regard to the other crops, rye is good; beets look good, but are believed to be deficient in sugar owing to the absence of South American fertilisers; wheat is fairly good; oats extremely good, and barley also excellent. The Germans have boasted to the neutral visitor that their artificial nitrates are just as good fertilisers as those imported from South America.
To come up to the standard of scientific and successful agriculture in England, it is deemed requisite that a tenant farmer, on renting an occupation, should have capital sufficient to invest 10 pounds, or $50, per acre in stocking it with cattle, sheep, horses, farming implements, fertilisers, etc. Mr. Jonas, beyond a doubt, invests capital after this ratio upon the estate he tills.
Their facile yielding to the argument that this great arsenal was principally of peace significance, owing to the fertilisers which it would eventually make, and the feeble backing provided for inspecting missions, were reflected in the semi-resistant attitude of the I.G. personnel.

Thanks largely to untiring work by Sir Leslie Scott who gave up the chairmanship of the society on his recent appointment as Solicitor-General the country is now fairly covered by societies for purchasing requirements co-operatively principally fertilisers, feeding-stuffs, and seeds.
If it was a mental consolation to fish fertilisers on the sea, have goruki for Russian literature, or to pose a favorite geisha beneath pine tree, it would be quite as much a mental consolation to eat dempura noodle and swallow dango. Instead of dwelling on such sham consolations, he would find his time better spent by washing his red shirts.
When the banks have been cleared of brambles to such a distance up the sides of the hollow as the ground suggests, and all poor or ill-grown trees have been cut away to let in the only two "fertilisers" needed air and sun the dimensions of the first pool or "reach" in the brook garden are decided upon. This must depend partly on the size and flow of the stream.
We have a better and richer soil, requiring far less expensive artificial fertilisers to maintain its fertility, and at a very much lower price. We can grow equally as good fruit; in fact, it is questionable if Florida ever produced a citrus fruit equal in quality to the Beauty of Glen Retreat Mandarin, a Queensland production.
Hence the character of the flowers on this beeless belt of mountain side is entirely determined by the character of the butterfly fertilisers. Only those plants which laid themselves out from time immemorial to suit the butterflies, in other words, have succeeded in the long run in the struggle for existence.
