CHAPTER VI.

DEVELOPMENT.

DEVELOPMENT.

The development of the child within the uterus of the mother

represents a chapter in the life history of every individual so

important in its relations to maternity and paternity that every young

man should be acquainted with at least its general features.

As stated in the chapter on Reproduction, every living organism begins

life as a single cell, or globule of protoplasm. In the case of the

human subject, the cell from which each child begins its development

is formed by the fusion of two cells or globules of protoplasm, one

furnished by the mother, and called the ovum, or egg; the other

furnished by the father, and called the spermatozoon. The egg is very

much larger than the spermatozoon, and contains enough yolk material

to afford nourishment for the embryo for a number of days.

When the ovum reaches the finished state, which is called "maturity,"

it leaves the ovary, and is carried along the fallopian tube (see

accompanying figure) into the uterus, where it usually finds a

lodgment in the upper part, as shown in Figure I. Once the minute ovum

has been caught in the projections of the velvety inner surface of the

uterus, this thick velvety lining of the uterus in the neighborhood of

the ovum begins a rapid growth, gradually enveloping the rapidly

expanding ovum, as shown in Figures I and II of the accompanying

plate.

Within the ovum there are taking place some of the most marvelous

changes in the whole life history of the individual. The nucleus of

the fertilized egg, and the protoplasm which surrounds it, divide into

two cells, then into four, eight, sixteen, etc. These divisions follow

each other in such rapid succession that there are many hundreds of

cells by the end of the first twenty-four hours. These cells soon

begin to arrange themselves into layers and groups, which, step by

step, develop the different tissues and organs of the body.

By the end of thirty days the little embryo, about as large as one

inch of the end of a lead pencil, would be recognized as the embryo of

some mammalian animal, but it would be quite impossible to say whether

it would develop into a human being or some other animal, if it were

seen quite apart from its immediate surroundings. By the end of

another thirty days, however, the little embryo has multiplied its

size several times, and has reached a form instantly recognizable as

the young of the human kind, as shown in Figure IV. It still, however,

retains the vestige of a little tail, which within the next thirty

days will have been completely absorbed.

[Illustration: THE FEMALE ORGANS OF GENERATION]

Note that the little two months embryo has projecting from its abdomen

a large structure which is labeled "cord." This cord is a part of what

is called the umbilical cord, and it is this that joins the embryo

to the mother. Note in Figure III the large stalk of this cord passing

upward from the body of the embryo and merging into the structures in

the top of the uterus. Note further that there are little branching

structures passing from the base of this stalk up into the base of the

uterus. These branching structures are loops of blood-vessels, and

they form part of the placenta, or "afterbirth." Through this cord the

embryo receives its nourishment from the mother. The blood of the

mother bathes these loops of blood-vessels, and the embryo absorbs

from the mother's blood the nourishment which builds its bones,

muscles, brain, spinal-cord, and glands. From the same source the

embryo receives the oxygen necessary for the maintenance of its life.

From the third month on to the end of the nine months, the amount of

material which the mother must provide for the development of the

child within her womb amounts to no small draft on her physical

resources. It is not at all uncommon for a mother in the later months

of pregnancy to become quite pale, her blood having been impoverished

to provide material for the development of her child.

MATERNITY.

What has been said above regarding the contributions which the

maternal organism must make toward the development of the offspring

must have impressed on the mind of the reader that _maternity means,

first of all, sacrifice_.

This sacrifice begins when the girl first enters upon womanhood.

With the expulsion of the ripened ovum comes, each month, a week of

special physical drain, when work must be lightened and vigorous

exercise curtailed, when exposure to cold or dampness may mean loss of

health.

Under these circumstances a woman should at this time deny herself the

pleasure of dancing; of skating or swimming; of sleigh-rides or

cross-country walks and the young man should make it less difficult

for her by acquiescing without question or demur in her request to be

excused from such recreation.

It is a fact that more sacrifice is involved in maternity among the

more highly cultivated nations of the human race than is true of

aboriginal peoples, or among the lower animals. Conditions of modern

life, and particularly urban life, leave the female organism less able

to endure the drafts made upon the system by maternity, so that to

bear a child may mean not only the sacrifice of comfort, but even the

sacrifice of health.

The highly sensitive, delicately adjusted nervous system of the woman

is perhaps more profoundly influenced than any other part of her

being. This manifests itself particularly in a heightened degree of

sensitiveness. It goes without saying that the pregnant woman

deserves at the hands of all who come in contact with her, and

particularly at the hands of her husband, most considerate and

sympathetic treatment. Her little whims and vagaries, however

unreasonable, must always be treated seriously, and with delicate and

tactful consideration. The members of her family, particularly the

husband, owe it to her and to her child to keep her in as happy a

frame of mind as possible.

When we consider the real significance of maternity to the race, to

society, and to the family, we must feel that, of all human relations,

maternity is the most sacred, and that no condition should be allowed

to mar it, and no consideration to take precedence of it.

PATERNITY.

After the husband had contributed the male sexual cells, or

spermatozoa, in this wonderful process above outlined, it might seem

that there is little he can do, except to wait, while nature carries

on the process. The reader will remember, however, from the chapter on

Reproduction, that the contribution of the spermatozoa only initiates

the sacrifices that the paternal organism must make in this process.

Are there any demands on paternity between the time of conception of

the new life and its birth?

As already mentioned under the preceding topic, the pregnant mother

needs gentle and loving care. She needs to have her little whims and

foibles overlooked. She needs to be protected, so far as possible,

from every influence that might depress or make her unhappy. She needs

to be guarded against any unusual physical exertion, and above all,

she needs at this time more than at any other time, the manifested

affection and sympathy of her husband.

There is another sacrifice, if it may be so called, which the husband

is called upon to make during the pregnancy of his wife, namely, _to

abstain absolutely from sexual intercourse during the period of

pregnancy and for two or three months following_. This means

practically one year of continent living. All other animals observe

this period of continence. Nature demands that man observe it in

common with other animals. Man is the only animal that has

transgressed this fundamental law of nature. The retribution which

nature metes out to the transgression of this law is various.

Sometimes, but rarely, the sexual excitement on the part of the woman

may cause an abortion, or a miscarriage. The more usual result makes

itself manifest in the drain on the nervous energy of the woman. When

we consider that maternity in the human race involves greater

sacrifice than in any other animal, it would seem that the addition of

this last demand, namely, of satisfying the sexual desires of the

husband during the period of pregnancy, might prove "the straw that

breaks the camel's back," and result in the more or less complete

nervous breakdown of the woman. The author submits this question to

all fair-minded men: Is it not due to the wife that she be not asked

to satisfy the recurring sexual desires of the husband during the

period when her life and its energies are so sacred to the race, to

society, and to the family?

The author submits this question because some men are known to

transgress this law of nature. Fortunately the proportion of men who

thus transgress is not large.

Let us stand for these things: (1) _An equal standard of purity for

men and women_, (2) _A strenuous, virile, continent manhood_, (3)

_Sexual temperance in wedlock_.

APPENDIX

APPENDIX.

Personal conferences and correspondence with young men regarding the

solution of their problems have brought out several questions that are

so frequently repeated as to make it evident that the answering of

them would serve the purpose of clearing up certain questions or

doubts, more or less important in the minds of many young men. It has

been decided to group these answers in an appendix rather than to

incorporate them in the body of the book, as many of them seem not

quite relevant to the topics outlined under the several chapters.

1. _How do we know that during the nocturnal emission the products of

the testes are not present?_

The spermatozoa found in the nocturnal emission, if present at all,

are found to be very much less active than the spermatozoa of semen

secreted during sexual excitement. The seminal vesicles are not

receptacles for the testicular secretion. The ampullæ seem to serve

that purpose in a limited degree.

Considering all these facts, it seems to be a tenable conclusion that

the few and sluggish spermatozoa seen in the product of the nocturnal

emission are those that have, from time to time, collected in the

ampullæ, and that during the time immediately preceding the nocturnal

emission the testes are not actively releasing nascent spermatozoa.

This function of the testes seems to be reserved for periods of

conscious sexual stimulation.

2. _How may one control too frequent emissions?_

If emissions are too frequent for the individual case, they are

followed by depletion and malaise. Even if they occur as infrequently

as once in two weeks and are followed by the above symptoms, they must

be considered as too frequent, or abnormal in that case. On the other

hand, they may occur as frequently as twice a week in plethoric robust

individuals, and especially in men who have had frequent sexual

intercourse, and who have for some reason discontinued it. And even

though they occur as frequently as twice a week, if they are followed

by a feeling of relief and wellbeing, they must not be considered as

too frequent for that individual under the conditions.

So the frequency limit of nocturnal emissions is more or less

independent of the time and quite dependent upon the reaction of the

individual to the emission. If, following the criterion above

outlined, one finds that his emissions are too frequent, because of

accompanying depletion and malaise, this frequency may be modified

either by changes of the diet or by changes of hygiene.

For a more extended discussion, see text above on nocturnal emissions.

3. _Do the organs of reproduction actually develop after the age of

seventeen or nineteen or even to the twenty-fifth year as is the

case with the physical and mental powers?_

The brain of an individual adds no nerve cells after a very early age.

The brain increases only very slightly in size and weight after the

age of puberty, and then only under special conditions and this

increase in weight and size is not due to the addition of any new

cells, but simply to a slight increase in the bulk of those cells

already present. In a similar way the sexual apparatus undergoes,

during the period of puberty (fifteen to seventeen) a very rapid

growth, reaching by the end of the period of puberty (seventeenth or

nineteenth year) their full size.

4. _Are enlarged veins in the scrotum dangerous?_

Enlarged veins of the scrotum represent dilatation of the veins of the

epididymis. These are thin walled vessels that respond to any

increased internal blood pressure, perhaps showing a special tendency

in this direction during that period of rapid growth of the sexual

apparatus in the early part of the adolescent period. If the

enlargement is only moderate, it may disappear, or at least become

spontaneously arrested in its growth, in which case it need cause no

concern. If these veins, however, dilate until they form a

considerable mass, known as VARICOCELE, they may affect the sexual

apparatus deleteriously in two ways: (1) The increased weight in the

scrotal sac may cause the sac to become elongated and to annoy the

subject by its traction on the spermatic cord. This lengthened scrotum

with its contents may also be exposed to mechanical pressure or even

to injury from the clothing, etc., which would not occur if the

scrotal sac were short, holding the testes close to the body. (2) Of

far more importance is the danger of the varicocele gradually

encroaching by pressure upon the testis, perhaps to cause a partial

atrophy of that gland. This condition is a comparatively rare one, and

inasmuch as it seldom occurs in both testes, the possibility of

causing sterility on the part of a man is remote.

The extension of the scrotum and the "bearing-down" sensation may be

relieved through the wearing of a suspensory bandage. Such a bandage

may be obtained at any drug store or surgical instrument house, and if

properly fitted, will usually relieve any such discomfort as described

above. If the varicocele is quite large, the subject will do well to

consult a competent surgeon and to take his advice.

5. _Is the emptying of the seminal vesicles thru nocturnal emission a

universal phenomenon among continent men?_

The nocturnal emission is not a universal method of emptying the

seminal vesicles. Some continent men never have nocturnal emissions.

The reason may be sought in one of two directions: (1) The usual cause

of absence of nocturnal emissions is to be found in the fact that in

the man in question the seminal vesicles are periodically drained by

_involuntary diurnal emissions_, occurring usually when the

individual is at stool. These emissions are likely to occur once in

two to four weeks and take the place of the nocturnal emission. (2)

Rarely we find virile, continent men whose vesicular secretion is so

scanty that they are never conscious of its emission.

6. (a) _Should a man who for three to six years of his boyhood

practiced masturbation think of wedlock?_

(b) _If one has not lived a pure life but has reformed, may he ask a

pure woman to be his wife?_

Such questions as these are very frequently asked and with most

serious motives. A vast majority of boys and young men who practice

self-abuse, do so either wholly ignorant of the fact that it is wrong

or cognizant only in a vague way of the evil of the practice.

To consign a man to the Hades of homelessness and the sorrow of

childlessness because through ignorance he lapsed from purity during a

few months or years of his life, would be meting out a retribution far

in excess of the sin. If nature intended such a retribution to be

meted out she would have led the way by causing an atrophy or some

other form of disease in the subject who had abused his sexual organs.

But nature does not do that. If the young man who, from his twelfth to

his eighteenth year, has practiced masturbation, is shown the error of

his way and breaks the habit absolutely, nature quickly comes to his

rescue and rehabilitates his virility completely, unless he has been

guilty of extreme excess in the habit. This rehabilitation of virility

after self-abuse is usually experienced in from one to three years,

according to the case and the extent of the practice.

The complete mastery of a habit after it has through years been

forging its chains about the youth, is in itself no small victory and

should go a long way towards extenuating his lapse. The young man who

can conquer himself and learn to lead a pure life, free from his early

habit and above reproach not only in his acts toward womankind but

also in all his thoughts of woman deserves his well-earned reward. He

deserves the respect of all pure women and should be able to win the

love of one whom he may with clear conscience ask to be his wife, and

with whom he may confidently expect to build a typical home.

7. _Should a man have intercourse for any purpose other than for

procreation?_

In the normal course of events, if intercourse is indulged in for

procreation only, it would come as often as once, perhaps twice in a

month; that is, either just before the menstrual period of the woman

or just after, the woman being most easily impregnated at these two

periods.

A man who has led a continent life before marriage should have no

difficulty in controlling his sexual appetite to that extent. If the

sexual intercourse occurs as infrequently as once or twice in a month,

the man, by living thus continently, will find it much more easy to

maintain his continence during the twelve-month period after his wife

becomes pregnant before he can properly have intercourse with her

again, than would be the case if he had had sexual relations much more

frequently.

That the man desires intercourse much more frequently than as above

outlined and that the woman, in the vast majority of cases, does not

desire intercourse except for procreation and about as frequently as

above indicated is, without any reasonable doubt, due to hereditary

tendencies. Under primeval conditions, and in fact, until

comparatively recent times, the vast majority of mankind were

polygamous, the strong men of the race--those who procreated their

kind--having as many wives as they could support and protect, the weak

men of the race being crowded aside, sometimes castrated, to become

the burden bearers for the strong.

Under conditions of polygamy the woman is rarely subjected to sexual

intercourse for other than procreative purposes, and even granting

that the man has intercourse for procreation only, if he had twelve

wives, he would be having it twelve times as frequently as any one of

them. That these experiences on the part of a long line of maternal

ancestors should lead the women of today to desire sexual intercourse

for procreation only, is easy to understand; that the impulses

transmitted along the paternal line of ancestors should lead the men

of today to desire intercourse far more frequently than this can,

under monogamous conditions be indulged, is also easy to understand.

8. _How frequently may sexual intercourse be indulged, in the marriage

state?_

If one is to overstep the bounds mentioned above, i.e., to indulge in

sexual intercourse once or twice in a month for procreation only and

not at all during the period of pregnancy and childbed period, the

limit is then set, not by strictly normal and anthropological

considerations, but by the health of the individuals. The author has

seen young married couples who had carried their sexual intercourse to

such extremes as seriously to deplete the physical vigor and menace

the health of both parties. Just how frequent indulgence will have

this effect in any particular case is impossible to say. In some cases

twice a week may have this effect; in other cases once in twenty-four

hours might be borne for a considerable time. In any case the

condition is an unnatural one and is certain to bring a natural

retribution in some form--either broken health, or sterility of the

wife, and depleted powers of the husband, or weak and sickly children,

separated by long intervals.

9. _How long is it possible for a young man to waste his vital fluid

and yet be able to raise healthy children?_

This question cannot be answered in other than most general terms. The

author has known one case of a young man who, for several years,

practiced masturbation several times a day, so far depleting his

powers that he could not walk erect, his muscles were flabby, his

testes were very soft and small, his eyes shifty, his hands clammy and

his mind incoherent in its working. He seemed to be a candidate for

the asylum and would probably have gone there if radical means had not

been adopted to break him of the habit. He was broken, however,

absolutely, and never performed the act after his nineteenth birthday.

Within three years he had completely recovered his virility. He had

nearly doubled in weight and in lung capacity and a large part of his

increased weight was in great bulk of muscle of high tonicity--muscle

which he had gained by heavy physical work upon a ranch. His sexual

organs had completely regained their tonicity and without doubt, their

virility. He had so far recovered mentally that he finished a course

of professional study and entered with great success upon the practice

of his chosen profession.

On the other hand, a middle-aged man consulted the author regarding

the sterility of his wife. After examination, it was found that the

husband had practiced masturbation about twice a week from the age of

puberty to his twenty-fourth year, when he was married. He assured the

author that at the time of his marriage his testicles were, as far as

he had known, similar to the testicles of other young men, and that

during his married life he had never had intercourse with his wife

more frequently than once in a month, but that during that time he had

noticed a gradual atrophy of the testes. At the time of the

examination only small atrophied remains of these testes could be

discovered. The sterility of the wife was due, without any question,

to the absolute impotence of the husband, and so far as the history of

the case would suggest, there was no other assignable cause of this

impotence than the eight years of masturbation.

From these two cases, it must be evident that no rules can be laid

down. In one case the subject recovered fully from a case of extreme

masturbation; in the other-case, a habit that would not be called

extreme resulted in impotence. It must be evident that the practice is

a dangerous one after puberty, as no individual can tell to which of

the above cases his may be similar.

10. _Granting that masturbation is harmful through loss of semen, is

there any compensation for this loss of semen in case of intercourse

with a woman?_

There is no doubt that an emission of semen following sexual

excitement is a draught upon the virile powers of the male animal. If

this sexual excitement is the artificial one cultivated by the

masturbator, the depletion seems to be more marked than is the case

with the normal, natural stimulation incident to sexual intercourse.

Some have suggested that the reciprocal influence of the woman can in

some way compensate for the vital fluid contributed by the male. It

is hardly likely that such a reciprocal influence is other than

psychical, but that is certainly sufficient to account for any

difference in these two forms of sexual gratification.

Nature calls upon the male animal to make a contribution for

procreation, which contribution is, always has been, and, in the very

nature of the case, always must be a certain tax upon the powers of

the male animal. When the intercourse is indulged for procreation

only, the male animal can well afford to make the contribution. Even

with that, the contribution which the male makes to procreation is

incomparably less depleting for him than are the contributions which

the female makes for her.

11. _Will vital fluid flow with every sexual intercourse?_

If vital fluid is present, and if the sexual intercourse is carried to

the point of causing an orgasm, there would, in all normal conditions,

be an emission of semen or "vital fluid."

12. _Is there any way to regulate intercourse so as to control the sex

of the offspring?_

While there are many theories upon this subject no one of them is

generally accepted by medical men.

13. _Will an intense and continuous desire on the part of a young man

for sexual intercourse cause a loss of seminal fluid?_

An intense and continuous desire for sexual intercourse will, without

question, cause an active secretion on the part of the testes, an

increased secretion on the part of the seminal vesicles and an active

secretion on the part of the prostate gland and of Cowper's glands.

The secretion from Cowper's glands will make its way along the urethra

and appear at the opening of that duct, probably soiling the linen of

the subject. The accumulated semen from the other glands will tend

rather to aggravate than allay the sexual desires. Such a condition of

the sexual apparatus is likely to cause a nocturnal emission,

relieving this tension and emptying the gorged gland ducts. If the

nocturnal emission does not occur, the sexual desires are certain to

return to occupy the waking hours more or less completely. If the

nocturnal emission does occur, it will carry away not alone the

vesicular secretion, but also more or less of the nascent spermatozoa

and other constituents of the vital fluid. Seasons of intense and

prolonged sexual excitement are in a high degree inimical to

continence, and even though the subject does not fully submit to his

inclination, his nocturnal emissions, which are likely to come

frequently, carry away the product of the testicular secretion,

thereby depleting to a certain extent, his virility. It is hardly

necessary to urge the importance of resisting these onslaughts of

sexual passion in their very incipiency.

14. _How may the habit of masturbation best be brought under

control?_

The first thing to accomplish is the purification of the thoughts. The

most effective way to purify the thoughts is to divert them to a pure

and strictly non-sexual subject--e.g., _pure mathematics_. The young

man who is trying to break this habit will do well to follow very

closely the rather strenuous regime outlined under hygiene in the body

of the book. If his condition is complicated because of the presence

of a very long loose foreskin, he will be wise to have this removed by

the simple operation of _circumcision_. If he should awake in the

night and feel the temptation to resort to his old habit, he should

resist the temptation in its first stage and instantly put his mind on

some subject quite foreign to his sexual apparatus. If he does not

succeed by force of will in diverting his mind from himself, the best

thing to do is to arise, dress and walk. If walking will not do it let

him run, and keep moving in the open air, under God's blue sky until

he is so tired he can hardly put one foot before the other. Then if he

will retire to his room, he will probably have no further difficulty

at that time.

15. _What influence has dancing upon the young man's solution of his

sexual problems?_

It hardly seems possible that a virile, husky young man, in his early

twenties, could be subjected for several hours to the conditions of

the modern dance hall, where he is brought into very close physical

contact with young women, dressed to expose their secondary sexual

features, perfumed to excite in a man his hereditary sexual

instincts; held so close to his partner in the round dance that he is

conscious of every movement of her limbs, and all of these under the

influence of artificial light and music--I say, it is hardly possible

for a virile young man to be subjected to all these conditions without

experiencing an extreme sexual excitement. That such an experience

often repeated not only does not simplify the young man's problem, but

seriously complicates it is not a matter of doubt on the part of

anyone who has studied these problems. All specialists in this field,

without a single exception, concur in the belief that the dance is a

device of the devil so far as the young man is concerned. That the

young women are, for the most part, quite innocent of the effect of

all these conditions upon their young men friends is also believed by

those who have studied the problem. If they were conscious of it, a

large majority of them would not longer consent to be the party to

such unfortunate conditions. The Square Dance, the Virginia Reel and

similar dances of the times of our grandparents are not remotely to be

compared in this matter with the modern Round Dance.

16. _May lost Virility be regained by use of "Remedies" or medicines

of any kind?_

No. Positively and absolutely, _No_. Many such nostrums are advertised

in the public prints. Many are sold by charlatans and quacks. No

reputable physician would hold out to his patient the hope that any

drug could bring back lost manhood.

_Lost manhood or lost virility may be regained by right living only._

The prescription for right living is as follows: _Live a continent

life_ and follow _a strenuous and sane regime of personal hygiene_,

such as outlined in chapter V above.

17. _Is the production of semen modified by nutrition?_

The production of semen is greatly modified by the state of nutrition.

Remember in this connection that semen is partly from the testes

(Spermatozoa) and partly from the vesicles and prostate. The formation

and release of spermatozoa is only slightly modified by the condition

of nutrition; while the rate of secretion from the vesicles is greatly

modified in quantity. This accounts for the fact that well nourished

men who eat heavily are very likely to experience frequent nocturnal

emissions, when living continently.

To Whom it May Concern:

It is with great pleasure that I pay a tribute of appreciation

to the excellent service of Dr. Winfield S. Hall, in his

presentation to audiences of young men of the vital problems of

sexual hygiene.

With the intelligence of a trained and experienced physician,

with the thoroughness and frankness of an expert teacher and

with the delicacy and motive of a Christian gentleman, he

presents the "Young Man's Problem" in such a way as to make him,

in my judgment, one of the most helpful counselors of young men

on the American platform today.

Sincerely,

My Dear Dr. Hall:

In your lecture on "The Young Man's Problem" and in your book on

"Sexual Hygiene" you are doing a great service for the rising

generation. I am convinced that one great source of vice is

ignorance about the matters touched upon in your lecture and

book. Priests are constantly giving instruction on these same

points, but it is a distinct advantage to have their teaching

reinforced by a distinguished physician, expressing himself with

the plainness of the laity and speaking always in a most

reverential spirit. For students seventeen years of age or more

your presentation of this difficult subject will be a God-send,

for it abates curiosity, dissipates ignorance, warns of perils

and arouses a manly desire for a clean life.

Very sincerely yours,

My Dear Dr. Hall:

Our committee wants to know if we cannot arrange a date with you

this year to deliver your lecture on "The Young Man's Problem."

I also want some more of your books on Reproduction and Sexual

Hygiene.

I cannot forbear to express my very hearty appreciation of the

splendid service you have done and are doing to the young

manhood of our country in this lecture and this book. I have

never heard a presentation of the subject which takes hold so

deeply upon thoughtful men, and your book is by all odds the

best thing in print on this subject. Your scientific, yet

popular method and the absence of vague moralizing are

convincing and inspiring in their effects. I trust we may hear

you this year.

Very truly yours,

I want to express my appreciation of your talk to boys on Sexual

presentation before the Boys' Conference at Lake Geneva the past

summer and it seemed to me that both in substance and in form of

presentation you hit the nail on the head in a way I had never

before seen it done. I believe that your contribution to boys in

this direction is to be even greater than that which you have

been making to young men.

Dear Doctor:

I wish to testify to the value of your lecture to boys from 12

to 16 years of age. You have touched a vital subject in a most

original way that impresses every boy that hears you. You lead

up to your "Secret of Manhood" in a manner that holds the

attention, impresses the truth you want to teach, so that it is

sure to be of lasting good.

This lecture I regard as the very best of its kind, which I have

ever heard.

I am more than glad to speak a word in commendation of your

lecture to boys on the "Secret of Manhood." To me it is the most

sane, safe and logical presentation of a much avoided subject

that I have ever heard. The boys at the Lake Geneva Conference

were strongly impressed without the undue excitement and morbid

curiosity that so often accompany the presentation of the

subject of "Personal Purity." And not only were the boys

benefited, but all the fifty boy workers present, representing

the entire Central West, had nothing but words of highest praise

for the way you handled the subject before two hundred older

boys.

I am glad that you are getting out material for a booklet on the

"Secret of Manhood," and shall be pleased to see the manuscript.

We are much in need of such a thing and believe the

International Committee can aid you in getting it out if

necessary. Yours cordially,

F.A. CROSBY,

Boys' Work Secy., International Committee. Y.M.C.A.
