of conflict。



His gaze has penetrated even the most hidden dwellings; those in which the

Halictus 〃varnishes her cells and makes the round loaf which is to receive

the egg〃; in which; under the cover of cocoons; murderous grubs devour

slumbering nymphs; even the depths of the soil are not hidden from him; for


there; thanks to his artifices; he has surprised the astonishing secret of

the Minotaur。



He sifts all doubtful stories; anecdotes; statements of supposed habits;

all that is incoherent; or ill observed; or misinterpreted; all the cliches

which the makers of books pass from hand to hand。



In place of repetition he gives us laws; constant facts; fixed rules。



With incomparable skill; he repeats and tests the ancient experiments of

Réaumur。



He is not content to show us that Erasmus Darwin is mistaken; he points out

how it is that he has fallen into error。 (7/33。)



He sets himself to decipher the meaning of old tales; skilfully disengaging

the little parcel of truth which usually lies beneath a mass of incorrect

or even false statements。 He criticises La Fontaine; and questions the

statements of Horus Apollo and Pliny。 From a mass of undigested knowledge

he has created the living science of entomology; which had received from

Réaumur a first breath of vitality; in such wise that each individual

creature is presented in his work with its precise expression and the

absolute truth of its character and attitudes; the inhabitants of the woods

and fields; whether those which feed upon the crops or those which live in

the crevices of the rocks; or the obscure workers that crawl upon the

earth; all those which have a secret to tell or something to teach us; the

Cigale; so different from the insect of the Fable; and above all that

beetle whose name had hitherto been encountered arrayed in the most

fantastic legends; the famous Scarabaeus sacer of the tombs; which Fabre

preferred to place at the head of his epic as an agreeable prologue;

although the inquiry relative to his amazing feats belongs chronologically

to a comparatively recent period of his career。



How moderate he is in such suppositions as he ventures; how cautious when

his persistent patience has at last struck against 〃the inaccessible wall

of the Unknowable〃! Then; with admirable frankness; tranquil and sincere;

he simply owns that 〃he does not know;〃 unlike so many others; whose

uncritical minds are contented with a fragmentary vision; and run so far

ahead of the facts that they can only promote indefinite illusion and

error。



One is surprised indeed to remark how few even of the most learned and

well…informed of men have a real aptitude for observation; and a highly

instructive book might be written concerning the discrepancies and the weak

points in our knowledge。 If they were subjected to a sufficiently severe

test; how threadbare would appear many of those problems which nature and

the world present; and which are regarded as resolved!



How long; for instance; was needed to destroy the legend of the cuckoo;

incessantly repeated down to the days of Xavier Raspail; and to us so

familiar; to elucidate its history; and to set it in its true light!

(7/34。)



It is by means of such data as these that a science is founded; for

theories decay; and only well…observed facts remain irrefragable。 With

stones such as these; which are hewn by the great artisan; the structures

of the future will be built; and our own science; perhaps; will one day be

refashioned。



For this reason Fabre's books are an education for all those who wish to

devote themselves to observation; a manual of mental discipline; a true

〃essay upon method;〃 which should be read by every naturalist; and the most

interesting; instructive; familiar and delightful course of training that

has ever been known。



On the other hand; it is impossible to conceive what labour this delicate

work demands; what perseverance Fabre has required painfully to extract one

grain of gold; to glean and unite the definite factors; the positive

documents; which served as foundations for each of his essays; lucid;

limpid; and captivating as the most delightful of fairy…tales。 We are

charmed; fascinated; and astonished; we see nothing of the groping advance;

the checks; and all the toil and the patience demanded。 We do not suspect

the long waiting; the hesitation; the desperate length of the inquiries。

For example; to establish the curious relations which exist between the

wasps and the Volucellae; what long and repeated experiments were needful!

His notebooks; in which he records; from day to day; all that he sees; are

evidence of this。 What watches in the alley of lilacs; year after year; to

decipher the mechanism and the mode of construction of the hunting…net of

the Epe?ra! Some of these histories; like that of the hyper…metamorphosis

of the Melo?; were only completed as the result of twenty…five years of

assiduous inquiry; while forty years were required to complete that of the

Scarabaeus sacer; for his observation of it was always partial; it is

almost always impossible to divine what one cannot see from the little that

one does see; and as a rule one must return to the same point over and over

again in order to fill up lacunae。



The majority of the insects which Fabre has studied are solitary; and are

only to be encountered singly; scattered over wide areas of country。 Some

live only in determined spots; and not elsewhere; such as the famous

Cerceris; or the yellow…winged Sphex; of which no trace is to be found

beyond the limits of the Carpentras countryside。



The proper season must be watched for; one must be ready at any moment to

profit by a lucky chance; and resign oneself to interminable watches at the

bottom of a ravine; or keep on the alert for hours under a fiery sun。 Often

the chance goes by; or the trail followed proves false; but the season is

over; and one must wait for the return of another spring。 The trade of

observer in many cases resembles the exhausting labours of the Sisyphus

beetle; painfully pushing his pellet up a rough and stony path; so that the

team halts and staggers at every moment; the load spills over and rolls

away; and all has to be commenced over again。



We can now cast back; in order to consider at leisure the immortal study

which marked the beginning of his fame; with the greater interest and

profit in that Fabre has been able; during his retirement; to generalize

and extend his discovery。 (7/35。)



Let us first of all note how the observation which Dufour had made of the

nest of the Cerceris was transformed in his hands; and what developments he

was able to evolve therefrom。



Since they have been definitely established by Fabre these curious facts

have been well…known。 They form perhaps the greatest prodigy presented by

entomology; that science so full of marvels。



These wasps nourish themselves only on the nectar of flowers; but their

larvae; which they will never behold; must have fresh and succulent flesh

still palpitating with life。



The insect digs a tunnel in the soil; in which she places her eggs; and

having provisioned the cell with selected gamecricket; spider;

caterpillar; or beetleshe finally closes the entrance; which she does not

again cross。



Like nearly all insects; the young wasp is born in the larval state; and

from the moment of its hatching to the end of its growththat is to say;

for a period of many daysthe grub enclosed in its cell can look for no

help from without。



Here then is a fascinating problem: either the victims deposited by the

mother are dead; and desiccation or putrefaction attacks them promptly; or

else they are living; as indeed the larvae require; but then 〃what will

become of this fragile creature; which a mere nothing will destroy; shut in

the narrow chamber of the burrow among vigorous beetles; for weeks on end

working their long spurred legs; or a
