ake courage to tell you the rest。〃
〃Indeed；〃 she said； 〃you make me quite ashamed； but confidence for confidence； I will tell you this； that I have never thought of any one but you in my life。 I looked upon you as one of those men to whom a woman might be proud to belong； and I did not dare to hope so great a thing for myself； a penniless working girl with no prospects。〃
〃That is enough； that is enough；〃 he answered； sitting down on the bar by the weir； for they had gone to and fro like mad creatures over the same length of pathway。
〃What is the matter？〃 she asked； her voice expressing for the first time a woman's sweet anxiety for one who belongs to her。
〃Nothing but good；〃 he answered。 〃It is the sight of a whole lifetime of happiness that dazzles me； as it were； it is overwhelming。 Why am I happier than you？〃 he asked； with a touch of sadness。 〃For I know that I am happier。〃
Eve looked at David with mischievous； doubtful eyes that asked an explanation。
〃Dear Eve； I am taking more than I give。 So I shall always love you more than you love me； because I have more reason to love。 You are an angel； I am a man。〃
〃I am not so learned；〃 Eve said； smiling。 〃I love you〃
〃As much as you love Lucien？〃 he broke in。
〃Enough to be your wife； enough to devote myself to you； to try not to add anything to your burdens； for we shall have some struggles； it will not be quite easy at first。〃
〃Dear Eve； have you known that I loved you since the first day I saw you？〃
〃Where is the woman who does not feel that she is loved？〃
〃Now let me get rid of your scruples as to my imaginary riches。 I am a poor man； dear。 Yes； it pleased my father to ruin me； he made a speculation of me； as a good many so…called benefactors do。 If I make a fortune； it will be entirely through you。 That is not a lover's speech； but sober； serious earnest。 I ought to tell you about my faults； for they are exceedingly bad ones in a man who has his way to make。 My character and habits and favorite occupations all unfit me for business and money…getting； and yet we can only make money by some kind of industry； if I have some faculty for the discovery of gold… mines； I am singularly ill…adapted for getting the gold out of them。 But you who； for your brother's sake； went into the smallest details； with a talent for thrift； and the patient watchfulness of the born man of business； you will reap the harvest that I shall sow。 The present state of things； for I have been like one of the family for a long time； weighs so heavily upon me； that I have spent days and nights in search of some way of making a fortune。 I know something of chemistry； and a knowledge of commercial requirements has put me on the scent of a discovery that is likely to pay。 I can say nothing as yet about it； there will be a long while to wait； perhaps for some years we may have a hard time of it； but I shall find out how to make a commercial article at last。 Others are busy making the same researches； and if I am first in the field； we shall have a large fortune。 I have said nothing to Lucien； his enthusiastic nature would spoil everything； he would convert my hopes into realities； and begin to live like a lord； and perhaps get into debt。 So keep my secret for me。 Your sweet and dear companionship will be consolation in itself during the long time of experiment； and the desire to gain wealth for you and Lucien will give me persistence and tenacity〃
〃I had guessed this too；〃 Eve said； interrupting him； 〃I knew that you were one of those inventors； like my poor father； who must have a woman to take care of them。〃
〃Then you love me！ Ah！ say so without fear to me； who saw a symbol of my love for you in your name。 Eve was the one woman in the world； if it was true in the outward world for Adam； it is true again in the inner world of my heart for me。 My God！ do you love me？〃
〃Yes；〃 said she； lengthening out the word as if to make it cover the extent of feeling expressed by a single syllable。
〃Well； let us sit here；〃 he said； and taking Eve's hand； he went to a great baulk of timber lying below the wheels of a paper…mill。 〃Let me breathe the evening air； and hear the frogs croak； and watch the moonlight quivering upon the river； let me take all this world about us into my soul； for it seems to me that my happiness is written large over it all； I am seeing it for the first time in all its splendor； lighted up by love； grown fair through you。 Eve； dearest； this is the first moment of pure and unmixed joy that fate has given to me！ I do not think that Lucien can be as happy as I am。〃
David felt Eve's hand； damp and quivering in his own； and a tear fell upon it。
〃May I not know the secret？〃 she pleaded coaxingly。
〃You have a right to know it； for your father was interested in the matter； and to…day it is a pressing question； and for this reason。 Since the downfall of the Empire； calico has come more and more into use； because it is so much cheaper than linen。 At the present moment； paper is made of a mixture of hemp and linen rags； but the raw material is dear； and the expense naturally retards the great advance which the French press is bound to make。 Now you cannot increase the output of linen rags； a given population gives a pretty constant result； and it only increases with the birth…rate。 To make any perceptible difference in the population for this purpose； it would take a quarter of a century and a great revolution in habits of life； trade； and agriculture。 And if the supply of linen rags is not enough to meet one…half nor one…third of the demand； some cheaper material than linen rags must be found for cheap paper。 This deduction is based on facts that came under my knowledge here。 The Angouleme paper… makers； the last to use pure linen rags； say that the proportion of cotton in the pulp has increased to a frightful extent of late years。〃
In answer to a question from Eve； who did not know what 〃pulp〃 meant； David gave an account of paper…making； which will not be out of place in a volume which owes its existence in book form to the paper industry no less than to the printing…press； but the long digression； doubtless； had best be condensed at first。
Paper； an invention not less marvelous than the other dependent invention of printing； was known in ancient times in China。 Thence by the unrecognized channels of commerce the art reached Asia Minor； where paper was made of cotton reduced to pulp and boiled。 Parchment had become so extremely dear that a cheap substitute was discovered in an imitation of the cotton paper known in the East as Charta bombycina。 The imitation； made from rags； was first made at Basel； in 1170； by a colony of Greek refugees； according to some authorities； or at Padua； in 1301； by an Italian named Pax； according to others。 In these ways the manufacture of paper was perfected slowly and in obscurity； but this much is certain； that so early as the reign of Charles VI。； paper pulp for playing…cards was made in Paris。
When those immortals； Faust； Coster； and Gutenberg； invented the Book； craftsmen as obscure as many a great artist of those times appropriated paper to the uses of typography。 In the fifteenth century； that naive and vigorous age； names were given to the various formats as well as to the different sizes of type； names that bear the impress of the naivete of the times； and the various sheets came to be known by the different watermarks on their centres； the grapes； the figure of our Saviour； the crown； the shield； or the flower…pot； just as at a later day； the eagle of Napoleon's time gave the name to the 〃double…eagle〃 size。 And in the same way the types were called Cicero； Saint…Augustine； and Canon type； because they were first used to print the treatises of Cicero and theological and liturgical works。 Italics are so called because they were invented in Italy by Aldus of Venice。
Before the invention of machine…made paper； which can be woven in any length； the largest sized sheets were the grand jesus and the double columbier （this last being scarcely used now except for atlases or engravings）； and the size of paper for printers' use was determined by the dimensions of the impression…stone。 When David explained these things to Eve； web…paper was almost undreamed of in France； although； about 1799； Denis Robert d'Essonne had invented a machine for turning out a ribbon of paper； and Didot…Saint…Leger had since tried to perfect it。 The vellum paper invented by Ambroise Didot only dates back as far as 1780。
This bird's eye view of the history of the invention shows incontestably that great industrial and intellectual advances are made exceedingly slowly； and little by little； even as Nature herself proceeds。 Perhaps articulate speech and the art of writing were gradually developed in the same groping way as typography and paper… making。
〃Rag…pickers collect all the rags and old linen of Europe；〃 the printer concluded； 〃and buy any kind of tissue。 The rags are sorted and warehoused by the wholesale rag merchants； who supply the paper… mills。 To give you some idea of the extent of the trade； you must know； mademoiselle； that in 1814 Cardon the banker； owner of the pulping troughs of Bruges and Langlee （where Leorier de l'Isle ende
