REPORT OF THE RESIDENT VICE-PRESIDENT FOR THE YEAR i886-'87.

J. A. HOLMES.

The Society has now completed the fourth year of its existence. And the result of its work during the past year, and of the three years preceding, afford the assurance that it may be now regarded as a permanent institution. Kind words of encouragement have come in from eminent sources; applications for the Journals of the Society have increased in number; the society has now on its exchange list Journals of many of the more prominent societies of the United States, and of several foreign societies; and there has been a steady improvement in the extent and character of the original in- vestigations being carried on by members of the Society.

It is worthy of mention, too, that the system of public lec- tures which was inaugurated at the State University by this Society has been adopted by other institutions in this and adjacent States. And the Secretary of this Society has been in correspondence with gentlemen connected with other Southern institutions who intend organizing similar Societies. We may believe, then, that this humble beginning made here less than four years ago, is doing something to awaken a new activity in scientific work not only in our own State but also in other Southern States.

The following summary will exhibit in a general way the

work of the Society during the past four years of its existence :

Public Lectures, — 4 — 3 7

Papers presented 67 43 60 53 223

Papers published 98 100 148 150* 500

The above table shows a decrease in the number of papers presented; but there has been a decided improvement in the length and value of the papers, that has more than counter- balanced the falling off in number. The Journal for 1886 and 1887, which is to be published in two parts, will proba- bly contain more papers than is indicated above. A detailed statement would show more clearly the growth of the Society; but this can not be given here.

But while the Society is making real advancement it is doing so under disadvantages. Its membership has not been increased as was hoped it would. The students and graduates of the University and odier institutions have not associated themselves with it, nor have taken part in its work as it was expected they might, and as it is hoped they will do in the future. Nor has the Society received the liberal finan- cial support which it needs to increase the publication of its Journals. The Society needs in every way a more generous support; and for this it must appeal to its members and all others interested in scientific work in the State.

Among the present and pressing needs of the Society I may mention the following :

(i) The hearty co-operation of a much larger number of persons in the State engaged in, or interested in, scientific work. All such should become members of the Society and co-operate with it in its work.

(2) A more liberal financial support. During the past year for want of funds the Society was unable to publish several papers presented for publication in the Journal. Among the members of other Societies are often to be found men of wealth and liberality who contribute largely to the financial support of the Societies to which they belong, and have won the title of "patrons' of the Society A few mem- bers of the Mitchell Society have contributed liberally to its

financial support during the past year; and it is earnestly hoped that this membership will increase.

{3) Contributions to the Library of the Society. During the past few months an encouraging beginning has been made in this direction, and it is hoped that much more will be accomplished during the coming year. The Society de- sires to collect together for preservation and reference, all books, pamphlets, manuscripts, maps, &c., that have any bearing upon the history, natural history, or resources of North Carolina, and any books, pamphlets, maps, &c., writ- ten by members of the Society, or workers in North Caro- lina. Already there has been collected together upwards of 400 such books, pamphlets and journals of other Societies.

A system of public lectures was organized again during this year, and three lectures have been given. These will be continued during the next year under the* direction of the council.

The Journal of the Society for i885-'86, published during the past year, was a pamphlet of 148 pages. The Journal for i886-'87 will be published in two parts of probably 76 pages each. Part I will be printed during the early summer. Part II will appear later in the year.

As a continuation of the series of biographical sketches Part I of the Journal will contain a short sketch of Prof. Mar- cellus Hentz. Part II will contain a sketch of the late Prof. W. C. Kerr.

The President of the Society, on account of ill health, has been unable to meet with the Society during the year; but in various ways he has given assistance and encouragement.

During the year one death has occurred among the Life Members of the Society: Right Rev. Wm, M. Green, Bishop of Mississippi, and one among the regular members. Col. J. B. Wheeler.

BUSINESS MEETINGS.

August 28, 1886.

Prof. Holmes in the chair. The date of the pubHc meet- ings was changed to the second Tuesday in each month. The condition of the Treasury was discussed and the Treas- urer was directed to advertise and place on sale the new Journals.

October 15, 1886.

Prof Holmes presided. It was directed that papers pre- sented before the Society be, as far as possible, on uniform paper, as to size at least, and that the Publication Committee take charge of the papers immediately after each meeting, deciding which are to be published and which placed on file, finally placing them in the hands of the Secretary.

Arrangements were directed to be made for storing the books and pamphlets belonging to the Society where they would be convenient for reference.

A Committee was appointed to take steps towards effect- ing an interchange of publications with other bodies having a like aim with this Society.

May 7, 1887.

Prof Holmes in the chair. The Secretary and Treasurer presented his reports.

It was ordered that the monthly bulletins containing ab- stracts of papers read at the public meetings be issued also during the coming year.

In view of this increase of the Secretary's duties and of the rapidly growing library of the Society the office of Record- ing Secretary and Librarian was created,

It is evident from the above table that the estimated expenses run con- siderably beyond the probable income, and yet these expenses are placed at a much lower figure than for last year. It is therefore essential that special contributions reach the society's treasury in order that the work be maintained as heretofore.

A SKETCH AND BIOGRAPHY OF NICHOLAS

MARCELLUS HENTZ.

N. M. Hentz was born in Versailles, July 25, 1797. To this place his flither, who was active in political affairs, had been obliged to flee from Paris, and conceal himself under an assumed name (Arnold). His son showed a remarkable talent for miniature painting while quite young, and attained considerable proficiency in this art. In 18 13 he entered the Hospital Val de Grace as a student in medicine, where he rem lined busied with his studies and duties as hospital as- sistant until the fall of Napoleon. At this time his %ther was proscribed and obliged to flee to America.

The family, after their arrival in this country, spent a few weeks in New York City and Elizabeth Town, when they removed to Wilkesburg, Pa., the latter part of April, 1816.

For some years Hentz was engaged in Philadelphia and Boston as teacher of French and miniature drawing. Fol- lowing this, for a short time he was tutor in the family of a weathy planter (Mr. Marshall) on Sullivan's Island, near Charleston, S. C.

While engaged as a teacher in a school for boys at Round Hill, Northampton, Mass., he was married to Miss Caroline Lee Whiting, the daughter of Gen. John Whiting, of Lan- caster. His wife afterwards became well known as a poet and novelist.

Soon after his marriage, in 1824, he moved to Chapel Hill, N. C, where he had charge of Modern Languages in the State University until 1830. From this time up to 1849, he was in charge of various female seminaries and academies in the South; at Covington, Ky., Cincinnati, O., Florence, Tuscaloosa, and Tuskegee, Ala., and Columbus, Ga. His health having failed, he moved to the residence of his son Charles, at Mariana, Florida; where he died Nov. 4, 1856.

It is a remarkable fact that during his long life as a teacher he was one of the pioneers in American Entomology, and became during his time the highest authority on American Spiders. His life and work then are of special interest to the members of the Mitchell Society because of his connec- tion with the University of North Carolina. All of his leis-

14 JOURNAL OF THE

ure hours, during his Hfe as a teacher, were devoted to these studies.

He was an intimate friend and co-worker with the well known entomologist, Harris, as the publications of the Bos- ton Society of Natural History will testify.

He was very fortunate in selecting the spiders as his special field of study, for little or nothing at that time had been pub- lished on North American Spiders. His time was given to the observation of their habits, and to the collection, descrip- tion and representation of the various species. He published a few papers in Silliman's Journal, and in the Journal of the Philadelphia Academy of Arts and Sciences, and then brought together his extensive series of notes and paintings, and offered them to the Boston Society of Natural History for publication in its Journal. The publication of these ex- tended over a number of years, A few years ago, as many of the publications were out of print, the Council of the So- ciety determined to republish, in a connected form, all of Hentz's arachnological writings. When this was done, a considerable number of notes and descriptions were added by Mr. J. H. Emerton, who has paid much attention to our na- tive spiders. A few notes were also added by Mr. Wm. E. Holden of Marietta, O.

After Hentz's death, his collection of spiders went into the hands of the Boston Society, but has since been nearly de- stroyed.^ G. F. Atkinson.

i6 JOURNAL OF THE

A NEW TRAP-DOOR SPIDER.

BY GEORGE F. ATKINSON.

In his excellent work on trap-door spiders, Mr. Mog- gride says, " There would doubtless be a just feeling of pride and satisfaction in the heart of a naturalist, who could say that he had made himself thoroughly acquainted with all the species of a particular group of animals, had learned their most secret habits, and mastered their several relations to the objects, animate and inanimate, vvhich surrounded them. But perhaps a still keener pleasure is enjoyed by one who carries about with him some problem of the kind but par- tially solved ; and who, holding in his hand the clue which shall guide him onwards sees in each new place that he vis- its fresh opportunities of discovery. The latter is certainly the condition of those who take an interest in searching out the habits and characters of trap-door spiders.'"

While many interesting facts, in the life history, and arch- itecture of trap-door spiders were observed and collected by Mr. Moggridge, he very modestly says that many remain yet to be gathered in ; that we are only on the threshold of discoveries of these creatures who have lain quiet in the earth century after century ; and that he will be satisfied to have been able to " hold the door sufficiently ajar to permit those who love nature and her ways to catch a glimpse of the wonders and beauties of the untrodden land that lies beyond."'

A favorable circumstance afforded me an opportunity for making some observations on the unseen " wonders and beauties of the untrodden land " which is the abode of these interesting creatures, and it is with a sense of pleasure that I note them.

Some time the latter part of May, or early part o( June,

1885, Mr. Meriitt, of Pittsboro, N. C, brought to Chapel Hill, two trap-door spiders with their nests, and placed them in the care of Prof Holmes, for the University of North Car- olina. The nests with their occupants were placed in the ground for the summer. On Nov. 12, after a careful search Prof Holmes was able to find only one, and this one with difficulty, as for some reason it had dug through the lower end of the tube and was hidden in the earth. Later I shall offer what seems to me may be an explanation of this. On the morning of the same day, the spider with its trap-door nest was placed in my keeping, which was the first intima- tion I had of the presence of such an agreeable neighbor.

At 4:3c, p. m., I placed 'dj4 inches of earth in a glass jar 5 inches in diameter and 7 inches deep. Two thirds of the surface of the soil was then covered with moss. In this the spider was placed, and the jar and its contents taken to my room, that I might, if possible, observe the operation of dig- ging the tube and making the trap-door.

The results were most gratifying. Just before going to supper, at dusk, I observed that the spider had not under- taken the work. Upon returning at 8:30, p. m., I found the task undertaken. The spider was resting m a hole about 2o"i.ni. deep by 22"^-™- in diameter, which she had excavated at iOne side of the jar. I placed the jar upon my study tabic, just beneath the light of a student lamp, so that while read- ing I could observe any movements made by my companion. The spider was resting in the hole with its legs partially folded, the anterior ones lying upon the edge of the exca- vation

After I had been quiet for some time the spider began to move cautiously, and turning about slowly, went head first into the hole, and dug from the bottom with her mandibles a pellet of earth about the size of a small pea. Then turning carefully around she placed it at the edge of the hole where she pushed it off with aid of her palpi, at the same time working her mandibles up and down. At first the spider seemed timid, and would cease operations upon the slightest movement on the part of myself During the course of the evening three other persons who came to my room had the fortune to witness the operation of digging out the earth. The spider soon became bold, paid no attention to move- ments in the room, and permitted me to watch her very closely. Occasionally, by using both palpi at once, the dirt was flirted suddenly from the grasp of the mandibles

i8 JOURNAL OF THE

with such force as to strike against the opposite side of the jar. Had it not been for this obstruction the dirt must have been thrown three or four feet.

After depositing each load on the edge of the hole the spider would turn around agai'n for another load, but before picking it up, she would project the posterior pair of spin- nerets about 5"^-™- from the abdomen, and carefully knead the viscid liquid upon and around the freshly placed pellet of earth, and over the edge for a distance of 4™-™- or 5 m.nt.^ for the purpose of making the soil adhere and prevent its caving in. In Plate I, Fig. 4, the spider is shown in the act of removing a pellet of earth from her mandibles. In ^ig- 5. is represented the application oi the viscid liquid. The ends of the spinnerets are applied to the surface alter- nately, as shown in the illustration. The legs took no part in the application of the viscid liquid ; nor did the liquid form a thread when the spinnerets were drawn from the sur- face, as I have since seen it when the spider was crawling about on the surface of the earth.'

At 1 1:30 o'clock, when the hole was about 4™-^^- in depth, to my surprise and pleasure the spider began to make the ** trap-door." Standing upon its fore feet and placing the spinnerets against the glass jar at the level of the edge of the hole, the spider covered the glass with the viscid liquid. Several pellets of earth were stuck to this, each time another portion of the viscid liquid being applied. After a depth of ^iii.m. j^^(-j been built up in this way, which was to answer as the hinge, the spider cut a sprig of the moss and cemented it to the hinge so that the end projected above it. Small sticks, particles of moss and earth were constantly placed upon the edge of the growing door. Each time the spider would come out of the hole for new material, retreat backward, and turn halfway around so as to apply it to the door. Placing the load on the under side of the partial door, she would care- fully move it up to the edge. Then placing the distal por- tion of the palpi and anterior pair of legs above, while the proximal portion of these limbs and the ends of the mandi- bles were on the under side of the pellet and door, she would

'As I am now writing, Jan. 16, 1886, 11:55, p. m., the spider is crawl- ing about on the surface of a freshly prepared jar of eanh. Sometimes the viscid liquid adhering to some object is drawn out in a band of silk 2m. m. wide, and the pieces of moss strewn on the earth are loosely matted together in the path of the spider about the side of the jar.

fit and press it in shape, as one would mold with the hand a moist portion of earth by pressing it into a thin sheet. This is illustrated in Fig. 7, Plate XXII. Indeed it looked very much like the black bony fingers of a hand performing the work of pressing. The greatest pressure seemed to be brought to bear upon the rounded ends of the madibles. After fastening on a portion thus, the spider would take an inverted position and apply viscid liquid along the edge and under surface of the door, as shown in Plate XXIII, Fig. 6. She would then turn about and crawl out for more material. The hole being by the side of the jar, I could watch the operation both in the hole and upon the cover. By I o'clock in the morning (Nov. 13,) the door was finished so that the spider could pull down the lid, which completely closed the entrance, nicely fitting in around the edge and appearing as if there was no hole nor spider, but through the glass the spider could still be seen.

At intervals during the construction of the door, the spider would pull it down to observe where the next pellet should be placed in order to make the door fit the circular opening of the tube. Discovering this she would turn completely around, and not being able with her head in the bottom of the tube to see the place where she intended to put the next load, she would find it by feeling about with her spinnerets. The viscid liquid would then be applied ^nd the pellet of earth fitted with extreme nicety. Satisfied with the result of my experiment I retired.

By daybreak I found that the excavation was continued after the completion of the trap-door, the soil being deposited around the nest to raise the surface of the earth in the jar to a level with the top of the nest. Without close searching it was impossible to detect the door.

The mode of making the trap-door by this spider differs very widely from that observed by other naturalists so far as I can find any record. Mr. Moggridge saw the female, Ne- inesia Meriodinalls, construct a trap-door in captivity. He made a cylindrical hole in a flower-pot of earth. Into this the spider disappeared. " During the night following the day of her capture she made a thin web over the aperture, into which she wove any material which came to hand. The trap-door at this stage resembled a rudely constructed, hori- zontal, geometrical web, attached by two or three threads to the earth at the mouth of the hole, while in this web were caught the bits of earth, roots, moss, leaves, etc., which the

20 JOURNAL OF THE

spider had thrown into it from above. After the second night the door appeared nearly of the normal texture and thickness, but in no case would it open completely, and it seemed the spider was too much disgusted with her quarters to think it worth while to make a perfect door.'"

He also records the making of a door by a very young one of this species, in which the threads, except at the hinge, were cut so that the door would open and shut.*

The only thing he records which seems at all analagous to the mode of making a trap-door exhibited by the spider in my possession is that manifested in the enlargement of nests and trap-doors by spiders as they grow larger, and consequently require nests of larger dimensions. This ope- ration was not witnessed by him, however, but the additions to the size of the door were proven by measurements and observations upon nests of young spiders at different seasons,'^

It would seem natural to suppose that, in making slight additions from time to time to the edge of the nest, the spider would cement pellets of earth, pieces of moss, etc., to the edge, instead of first spinning a web ; unless the web is spun over the lower side of the door and made to project just far enough to fit the enlarged tube. In Plate XXIII, Fig. 8, can be seen eight concentric " lines of growth," as they might be termed, of the trap-door, corresponding to the growth and needs of the spider. These I judge to represent the succes- sive enlargements of the door concomitant with the enlarg- ing of the tube. We can safely say that these additions were made by cementing the material, piece by piece, which forms each ring, to the edge of the door. These " lines of growth " are not present in the door made by the adult spider in cap- tivity. I induced the spider to make the door the fourth time, (Jan. 19, 1886,) in order to observe if there was any regularity in the cementing of the particles, which might form these lines of growth in a door made by an adult spider. There is no such regularity. Indeed his last door was made of about a dozen very large pellets of clay, which, being very plastic, the spider was able to press each pellet into a sheet of considerable dimensions.

It is to be regretted that Mr. Moggridge did not have the

'Harvesting Ants and Trap-Door Spiders, p. 118. 'Harvesting Ants and Trap-Door Spiders, p. 119. ^Idem. pp. 123. 127 and 150, and Supplement, p. 245.

ELISHA MITCHELL SCIENTIFIC SOCIETY. 21

opportunity ©f observing the manner of enlargement of trap- doors made by the spiders which he studied, or that he did not offer some theory as an explanation. If the particles are cemented to the edge, it would be quite natural that the spe- cies of spider in my possession once made its door by first spinning a web across the mouth of the tube, and then weav- ing into it other material, as in the case of N. meridiortnlis; and that the habits, followed through life and successive gen- erations, of making additions to the door by cementing par- ticles to the edge, finally became so fixed that this mode of making additions to it became the permanent habit and type of construction of the trap-door from the foundation ! The rapidity, ease, and intelligence manifested in this method of building up the door, piece by piece, certainly indicates a higher development of instinctive power. A perfect and neatly fitting and swinging door made in i y^ hours !

When I took the spider from her nest it was necessary to remove nearly all of the soil from the jar and take her from the lower end of the tube, as all efforts to attract her from the nest failed. As the soil was very loose and the nest not long made the walls of the tube collapsed. In ten days the spider was returned to the nest. Though the trap-door was capable of being used, and seemed to satisfy the spider's idea of the " fitness of things," it was in a very dilapidated condi- tion. This agrees wnth. what Mr. Moggridge says of the re- luctance manifested by spiders to abandon an old nest. The examples cited by him are that if a door be pinned back, during the night a second door will be made ; that if the nest be covered with earth the tube will be prolonged to the surface of the superimposed earth and a new trap-door will be made ; and that in some cases nests become inverted, when, a door being made at the now upper end of the tube, the nest will have a door at each end ! ' The conduct of my spider under another condition farther illustrates this feature. Wishing to observe the habit of the spider if possible while the door of the nest was closed, I prepared a glass test tube, jyiri.m. jj^ diameter by placing, 4*'"' from the mouth, a cork bottom, so that the spider might have something on which to stand while making the door. This, with the spider in it, I placed in the glass jar and surrounded it with earth to darken the walls, hoping thus, because of the firm smooth surface of the tube she would not line it with silk, and by

'Harvesting Ants and Trap-Door Spiders, pp. 121 and 122.

22 JOURNAL OF THE

lifting the tube from the soil I could observe the position of the spider as it held down its door. The experiment was a decided success.

This was prepared at eleven o'clock on the night of Dec. 27, '85. Pieces of moss were strewn about the tube. By morning a perfectly fitting door, beautifully covered with moss had been constructed (Plate XXtV. Fig. 3). About this time many visitors came to see the spider, and in pulling at the door to show how persistently she would resist its being opened, the hing became loosened, and the door was pulled down upon her. She held on to the door with such tenacity that I pulled it into bits in my efforts to remove it from her grasp. It was removed Dec. 30, '85, and on the following night she built another as neatly as the first. The hinge to this became loosened and the door moved down about 5™-"i- from the mouth of the tube. Here she strength- ened the hinge by spinning a broad piece of silk, the width of the hinge, from the door down on to the wall of the tube. Several times in endeavoring to open the door I tore pieces from its edge and in every instance the spider repaired it. Finally, when I wished to remove her from the tube I was obliged to push up on the cork bottom, and in this way crowd her out through the door. After this was done it was with some difficulty that she freed her posterior feet from the silk bag which she had constructed at the bottom, so firmly did she hold on.

I have this yet to add. In a note I have mentioned the wandering of the spider about in a jar of freshly prepared earth, Jan. 16. For three days she has been restless, and though several attempts have been made to dig a tube she has failed. I came to the conclusion that the soil was not such as she could work easily or satisfactorily. Wishing to have soil which would make a more desirable tube than the loose soil in which I saw the first nest made, I used a large proportion of fine plastering sand mixed with black earth. This was wetted, and pieces of moss strewn over the surface. She tried several times to take up pellets of the earth, but seemed to be disgusted with its crumbling. She then tried to bore a hole by pushing down with her mandibles while turning her body around. She evidently wished to hide her head from the light, for after making a hole 2"^"' deep she re- mained with her head at the bottom. To-day, Jan. 14, '86, the soil in the woods having thawed sufficiently 1 prepared a jar of moist, ferruginous clay, very much like that of which

ELISHA MITCHELL SCIENTIFIC SOCIETY 23

the nest is constructed that came from Pittsboro. Upon this I put a fine mat of fresh moss, coverin^^ the earth except a spot at one side 2}4''^*' in diameter. In this I placed the spi- der at noon. I then covered it from the h"^ht. As I returned to m}' room after dinner she was restini^ in a hole 3 '"' deep which she had excavated, and small pellets of earth were placed against the moss at the mouth of the hole. She would not work durini^ the day unless I covered the jar from the light. During the evening, by lamp light, I had the pleasure of seeing her make another door. It required about I j/ hours. Only one piece of moss was used and that I let drop into the hole while she was at work. This seemed very strange for the tube was the onl)' i)lace not covered with moss, and to save her the trouble of cutting the moss I had strewn loosened particles about the hole. In this case all of the earth used in the con.struction of the door was taken from the bottom of the hole. The door being made almost entirely with the clay was v^ery conspicuous in comparison with the surrounding moss ; though the door fitted ver}' neatly, the tube being built up to a level with the top of the moss. This time instead of making the hinge against the side of the jar, it was made on the opposite side of the tube.

I was unable to understand how the resistance to opening the door was offered, if the spider fastened its fangs and (ill of its claws into the under surf ice of the door, as Mr. Mog- gridge states.' A reference to Plate XX I \'. J'^gs. 3 and 4, will show the results I reached in the experiment when the spider was induced to make a trap-door to the mouth of a glass test tube. The portion of the tube from h to r was not lined with silk. The spider, evidentl)' not admiring the cork at (/ for a bottom to her nest, carried in pellets of earth and bits of moss as shown at </. .She then spun a short bag of silk, /', which was attachnd b)- the mouth to the walls of the tube at (\ and resterl on the piece of cork. The mouth of the test tube was lined with silk froui the edge for about -„,.,... to 7 '■'■•"•. The ends of the silk lining at />] and the silk bag at r, were for some flistance transparent so that J w as enabled to see the spider fairl)' well. As can be seen in fig. 14, the si)ider clings to the bag of silk at the bottom (or walls of the tube) with the claws of her two posterior pair of legs, and to the under surf ice of th(' door with her fin<'"sand

24 JOURNAL OF THE

the claws of her anterior pair of legs. By partially lifting the door I was enabled to see the hold upon the door, and when I pushed the spider out of the tube, as before stated, I found her feet entangled in the bag of silk. The manner in which this spider holds down the nest is precisely the same as that described by P^merton' in the case of Cteniza Calif or- nica, except that he states the " 3rd and 4th pairs of legs are pressed out against the walls of the tube."

The nest of this spider belongs to the simple, unbranched type with shallow cork door. The door belonging to the nest in which the spider was caught (Plate XXIV. Fig. i,) measures 3 to 4™-™- in thickness ; the edge is beveled and fits neatly in the mouth of the tube. The door measures 2^m.m. across near the hinge ; the tube 6o"^*""- in length. The walls are badly collapsed and the lower edge ragged and open. It will be remembered that the spider was found in the earth below the tube when the nest was taken up in No- vember. The first nest which the spider made under my observation was open at the bottom, and when I attempted to take her out, finding she could not hold down the door she attempted to bury herself in the soil at the bottom of the tube. The question naturally arises, Is this not left open as a last means of escape from enemies ? I am inclined to think it is, in some cases at least with this species, as this is the only resort for safety after the door is open. Further observation is needed on this point. The trap-door of this nest is so hung that it tends to close itself. In Fig. 2, Plate XXIV. at (I are patches of silk that are drawn on the stretch when the door is open. When all resistance is removed these tend to close the door.

The subject of the food of trap-door spiders is an interest- ing one, and much is yet to be learned of their habits in this respect. While I had the spider out of her tube I offered her several house flies, holding them by one wing, with the forceps, near her head. The struggles of the fly attracted her attention. With a quick sweep of the palpi and anterior pair of legs she would clutch the fly and place it between her powerful mandibles, crushing it immediately. She held some of these about one minute, but I very much doubt her having derived any nourishment from them. One of the smaller species of the flies belonging to the genus Tabanus was offered her. It seemed only to frighten her as she could

not be made to touch it even by being angered, but would turn and run away as if in great fear. After returning the spider to her nest, Dec. 8, I placed in the jar two ants and a small carabid beetle. The ants hid themselves in the earth. Dec. 14th, the beetle was still unharmed and I concluded the spider did not come out for food. I then lifted the trap- door and placed the beetle inside. Dec. 16, I found the bro- ken hard parts of the beetle strewn about just outside the nest. It had been killed, the soft parts eaten by the spider, and the parts of the skeleton ejected from the nest. Jan. 17, 'S6, I placed a half dozen large yellow ants in the jar.' As they attacked her she would catch and crush them but I did not see that she ate any of them.

Jan. 2, '86, which was like a summer da}' at Chapel Hill, I went into the woods for the purpose of collecting some mo.ss. While tearing up a large patch of this, at the foot of a tree, I discovered a hole which I thought to be the nest of a trap-door spider. I dug down into the tube and found at the bottom a spider belonging to this family. In the after- noon I found several nests and one more female spider. Under some stones I found a male. I placed them in jars of earth containing moss. One of the females escaped ; the other built a nest and made a slanting double door, which might be compared to an outside cellar door. Each door is made of moss cemented with silk and hung by a semicircular hinge. These the spider will open and shut at pleasure, sometimes fastening them together with a thread of silk. In both of the nests in which I found these spiders, there were the lemains of ants. I had intended to illustrate and describe farther the nests and habits of these found by myself at Chapel Hill, as they are lively creatures and seem to offer interesting objects for study as to habit, food and architect- ure. But as this article is already long, and I wish to make further collections and study their habits more closely in captivity I will reserve the subject for a future time.

A FAMILY OF YOUNG TRAP-DOOR SPIDERS. "^^ (Pachylomerus, 4 — spinosus.)

Two questions were asked by Mr. Moggridge about the habits of young trap-door spiders. For the answer to these he was unable to inake any observations, so far as the record shows. The questions are ; 1st, do young traprdoor spiders make nests like those of the parent without being shown ?

2nd, do the males of trap-door spiders make a nest with a trap-door when very young ? To the first question we would almost unhesitatin<^ly reply in the affirmative, without direct observation. In regard to the second, it is well known by those who have given much attention to the habits of trap-door spiders, that the mature males, at least, do not build trap-door nests, but seek a hiding place under stones, logs, etc.

There is also another question as to the constancy with which species follow a unifonit type in the construction of their nests. Some naturaHst make the different kinds of nests a partial basis for classification, and others are looking for differential characters manifested in the variationsof the trap-door; whether the door is horizontal ; the hinge lower or higher than the distal part of the door sloping one side, etc.

Tlie object of this paper is to present the variations pro- duced by a family of 2(S young trap-door spiders, in the building of their nests, which I have carefully observedand noted. I trust also to show that, from the labors of these little creatures, and of several mature ones, which I have had in captivity, a great deal of light is thrown on the questions stated above.

The family was captured by D. E. Woodly, student at Chapel Ilill.'N. C, March 17, 1886. The mother had either deserted her children, or liad met with her death. The tube was doorless'and near a decaying stump. The 28 childre n were living ))eacefully together in the silken cocoon which had contained the e^i^s at the bottom of the tube. A fter keeping them together in a small vial for one day, I prepared a bottle of earth for each one. The bottles measure i Yz inches in diameter by three inches deep. In each about I Yi inches in depth of earth was placed. The earth was moi.st, loose, but smoothed over and gently packed to furnish a smooth surface for operations.

The following table shows the time of beginning and com- pletion of the work of each. In column 4 is given the time when the work bei^an which was carried to completion. Some began work earlier than here in dicated but aban- doned it.

* Nest was. destroyed and another built.

Variation'^ fvdin the normal ti/pr. By the normal type is meant that which seems to be the simplest, most nearly per- fect, plan of construction, is followed by a majority of those observed, and seems to indicate a vafiind hisifind, a more potent influence of inherited habit in some, while in others the instinct seems to be latent at first and gradually unfolds with the dawning of consciousness ! According to the nor- mal type, the spider takes up pellets of earth with its man- dibles, and turning around, places them upon the soil by the side of the tube, which is being dug ; or carries or throws them to a short distance. Occasionally with its spinnerets it applies viscid liquid to the pellets and QdgQ of the tube, much as an artificer would alternately place cement and bricks in the construction of a column. The trap-door is built in the same manner, by beginning, at one side of the

ELISHA MITCHELL SCIENTIFIC SOCIETY. 29

edge of the hole, a horizontal wall to which particles are ce- mented and pressed in shape to make a flat, circular, lid to the tube.*

By a study of Plate IV we shall see some of the variations from the normal type. Vig. i, a, represents one of the spiders, natural size, />, section of a nest built after the nor- mil type, door represented open, alsonitural size. All of the other fig-ures, except 15 and 16, are mignified. In fig. 2, one side of tube, a, is extended above ground and carried over the tube. The door, represented open, is hinged at /> ; when closed it slopes downwards from the hinge attach- ment, fig. 3. This was the work of No. 3. The arched wall from fi, was pressed in shape in the same way that the trap door is, so that when the spider began it at n, I thought it had begun the trap door, and m ide this entr}^ in my notes: "At 4.30 door begun ; two-thirds of the edge used for attach- ment of the hinge, making an awkward door." When the hinge was m:ide at A, it was easy to see the arching of the wall was intentional. In fig. 10, the tube is curved above ground in a similar way, but the hinge is at one of the slop- ing sides, m iking a door that swings to the right and left in- stead of up and down. This wms mideby No. 25. Fig- ures 4, 5, 6 and 7 represent the work of No. 15. A trench was dug, using the excavated eirth for a wall on each side ; the walls were then united by an arch over the middle, one end closed and a trap-door made at the other end. Fig. (S, represents the nest of No. 22, built in the same way as that of No. 15, except that at a, the hole was not entirely closed. No. 13 built what is shown in fig. 9. A trench with a wall each side was first built; in the middle of the trench was due the tube and the door hinged at the base of one wall at *-/, with the distal part of the door elevated at h.

Nests of mature spiders, of this genus made in captivity present some of the variations mentioned above, as also some of the nests found in a state of nature.

One of the most interesting things which came under my observation during the work of these spiders was the vary- ing potency of instinct manifested in the aptness with which each performed the task of building its home. This will be best illustrated by giving a few of the more striking ex- amples recorded in my notes. No. 6, was placed in the bottle at 10.30 p. m. and began digging the tube in the nor- mal way at 11. 15 p. m. It worked rapidly, sometimes aking up and unloading a pellet of earth in 10 seconds. Indeed it worked with as much ease, accuracy, and apparent thoughtfulness, as the mature one which I have described in the previous paper. Sometimes with its palpi it would flirt the pellet across to the opposite side of the bottle. It began making the trap-door at 12.30 a. m. and completed it at i a m. ; one hour and forty minuts from the time it began work, and two hours and thirty minutes from the time it was placed in the bottle.^ During the operation every move- ment seemed to facilitate the work. No. 19, was placed in the bottle at 6.30 p. m. : my notes read as follows : — "Began digging tube in normal way at 7.50. Does not seem to be satisfied with work, and begins in another place. This is done several times : 915 began making trap-door," etc. No.

26 was placed in bottle at 9 p. m., Mar. 19th. At i p. m., Mar. 20th, it began digging and soon abandoned this place for another. This it repeated as many as a dozen times, sometimes returning to the work and tearing away at the soil as if in a frenzy, and impelled by some irresistible power. Then suddenly leaving the spot it would wander and endeavor to climb the side of the glass ; when it would as suddenly be seized with an irresistible inclination to tear away at the earth without any seeming purpose. Occasion- ally it seemed to work with more deliberation, as if it were gradually becoming conscious of a latent instinctive power! At 4 p. m. it continued work in one place until the nest was completed, but the door, which is represented in fig. 13, was barely hung together and was loosely hinged by three strands. A few days later I tore down this nest, when the spider went to work in the normal way and built a perfect nest. Upon this point alone it would be interesting to fol- low carefully the notes I have taken on all, but I fear it would make the article too long, so I will conclude this sub- ject with reference to a few others. One without digging in the normal way pressed the dirt aside ; buried itself, and then spun a bag of silk surrounding it. When removed from this it went to work in the normal way. Several others acted very much like this one, and No. 26.

These variations could not be attributed to a difference in the nature of the soil as in the case of variations noticed among adult spiders, when the soil at times was of a differ- ent character. Care was taken that the soil should be of the same compactness and moisture for each. In some cases a hard lump caused the spider to remove to another place, and in one or two instances the spiders waited so long before be- ginning work that the soil was too dry ; pouring in water packed the earth too hard and it was necessary to loosen it before the spider could take up a pellet. With close watch- ing and due allowance for conditions just mentioned there seems to be great variableness in the attitude which different young individuals at first show in the construction of their nest. In some cases the consciousness, if fit might so be called, of instinctive power flashes upon them when they first are made to shift for themselves ; while with others there seems to be a greater or less development or dawning of the same consciousness.

Mr. Moggfidge also asks at which end of the tube the spider begins to spin the silken lining ? This pecies, so far

as I have observed, (I have watched over thirty individuals,) always be^jins at the upper end. I had several opportunities of witnessing this among the young ones, and one mature one,* when the spinning of the lining was done very beautifully. In fig. 14 a spider is represented in the act of spinning the silken lining at the upper part of the tube. When the viscid fluid coming from the spinnerets cools before it is applied to an object it forms a broad band or ribbon as it might be called ; by elevating and depressing the body perpendicu- larly as shown in fig. 14, and touching the spinnerets here and tiiere to the wall of the tube this ribbon of silk is fas- tened. By moving around the tube at the same time the lin- ing is made complete for the perpendicular distance covered by the spider in its movements. Some times instead of ele- vating and depressing in the manner just described the spider will move around the ^tube fastening the ribbon in circles.

Figs. 15 and 16 represent a novel way of excavating a hole which I witnessed in the case of a mature spider. With its legs as supporters on each side of the tube it would elevate its abdomen in the air and hook its mandibles in the earth at the bottom of the hole ; then revolving through a quadrant about the axis at n^ fig. 15, it would bring the earth to the surface and push it off with its palpi, as shown in fig. 16.

From this study we may conclude the young of trap-door spiders build their nests instinctively ; that males as well as females build trap-door nests before the sexual character and habits are well developed, which in the case of the males make a somewhat wandering habit necessary in order to find the females ; that young and old vary in making their nests from the normal type, so that die position or relative sloping of the door or tube could not be of any value in the classi- fication ; that this species does not use its legs to aid in spin- ning the lining to its tube, and that they spin the lining at the upper end of the tube first ; and lastly that they vary in the degree of skill manifested as artificers and the maturity of instinctive power.f

Note. — The doors of all the young trap-door spiders' nests are very thin, from 2 to 3 °"^. in thickness. One spider worked so rapidly tliat it would sometimes pick up and unload a pellet of earth in 8 seconds. As a rule they required a much longer time than this.

DESCRIPTIONS OF SOME NEW TRAP-DOOR SPIDERS; THEIR NESTS AND FOOD HABITS.

A few months after writing the previous article, "A new trap-door spider," I found a specimen which differed so markedly in color from the one, the subject of that article, and agreed so closely with the one described by Hentz as Mycfih' cnrolinensis,' now Paclnjlnmomis cfrroh'jK'ih'sis^' Hentz, that before having an opportunity to study them carefully I concluded the only difference was in color. Just after the article "A family of young trap-door spiders," w^as ready, I discovered that the two forms were different species ; that' the one called *'A new trap-door spider,', and the young spiders whose work has just been described in the Ento. Am. were both new species : the former I have called Pachylo merits carahivoruSy and the latter Pachjjlonierus Ai-sjnnoHUs.

been described in the articles referred to. One thinc^, how- ever, in regard to P. canibivorus is worth adding. The last trap-door made by this species as described on p. 20 was in sharp contrast, being made almost entirely of clay, with the surrounding moss. In a k\w days the spider made an exam- ination of its work and found it had made a mistake in not placing moss in the door. It reiTiedied this as well as pos- sible by cementing moss to the edge of the door and press- ing the ends down so that about half of the door was covered with moss !

NeM of FacJiylomeTUf^ turns. March 5, 'S6, on turning over an old log, a sudden movement of an object downward attracted my attention, I looked and discovered a silken tube, with particles of earth and leaf mould attached extend- ing above ground. On one side the silk was so extremely thin as to afford a "window" to the spider's house ! It was through this that I had discovered the movement which at- tracted my attention. Nearly the entire remaining portion of the tube was covered with earth and leaf-mould, and here the silk was thinner than in other portions, yet intact. It seems almost incredible, yet from the wonderful intelligence manifested by these spiders, I was led to think this ''window" had been purposely made : that the spider would sit by it and watch for beetles crawling about under the log, and see- ing one would rush out through the door, seize its prey and return to its tower ! It seems more reasonable when we consider that Nidivalvafd inarxn (see food habits of this species,) will nightly open its doors, remain out of sight, watch for passing insects, and rush out and seize them. The tube was about 8cm. in length, and there was only a very shallow excavation in the clay soil. The door is of the "wafer type," and was fastened down by silk, probably in the fall when the spider prepared for hibernating.'

In the evening I placed the spider in a bottle of earth. During the night it burrowed into the soil and made a rude door, which appeared more like a flap hung from one side of the mouth of the tube. On the evening of Mar. 7, I re-

'Mr Mog^ridge says in Harvest Ants and Trao-door Spiders, Supple- ment, p. 286 : *I have on very few occasions, found the doors of a wafer or cork nest.spun up during the winter at Mentone, and on dig- ging have discovered the spider alive, though partially torpid, inside ; but this I think is quite an exceptional event. I should like to know however, whether this becomes the rule in the case of the nests of those

moved a portion of the soil and placed in a portion of clay intermixed with loam, scattering over this a few bits of moss. I did not see the spider make the burrow, but next day saw it make two-thirds of a door, when I put an end to opera- tions on that nest. The door was made practically in the same manner as that by P. carahivorus, but was a wafer door.

From the appearance of the tube and the soil about it in both of the nests made in captivity, I felt sure this spider did not dig the hole in the normal ivaij. Accordingly, Mar, 8, I prepared a jar of wet clay. Up to 1 1 p. m. the spider had not begun work, but in the morning the work had not pro- gressed too far for me to observe it. The spider begins the burrow in a manner similar to that practiced by Nidivalvata Marxli by pressing the earth aside from a central point with its anterior legs, using also its mandibles, but it is much slower in its movements than' N. marxii. Paehy/omerus turris is the spider represented in fig. 15 and 16 of Plate III. excavating in a "novel way." In making the trap door, sometimes when in this position tt would cement the particle to the door by pressing on top of the door with its posterior legs, against the ventral surface of the cephalotho- rax. When the hole was about 3cm, deep it would occa- sionally take earth out in the normal way.

It will be seen that the habit of this spider is not wholly nocturnal in building its nest During the month of July while I was at Ithaca, N. Y., I had a specimen of P. carahi- vorus make a nest for Prof. Comstock. This was made en-

trap-door spiders which inhabit climates less favored than that of Men" tone." He also speaks of a Lycossa that is said to close her nest in Can nes in winter. I.atreille, in Mem Soc. Hist. Nat. Paris, (an VII, de la Repubique) p. 124, says "L'araignee tarentule ferrae aussi son habitation, mais cet opercule n'est pas mobile, et n'est construit que pour I'hiver." I have on stveral occasions found that P. cnrahivorus. after eating one or two beetles, fastens down the lid with silk. Nklivalvafa Marxli, I have found fastens the door at times (See Amer. Nat. \o\. XX, p. 592.)

O. P. Cambridge, in Annals of Nat. Hist 1878, 5th series. Vol. I, p. 107, says that in all cases that came under his notice the upper extremity of the nest of ^f?/p?t.s' p/Vf'u.s was without any perceptible orifice. He finally came to the conclusion that the spider gnawed its way out and then closed it with fresll thread again. These examples seem to indicate that spiders will very frequently at least fasten the doors to their nests during a period of rest, when inactive and more liable to be injured, when hav- ing had sufiicient food, and perhaps sometimes at regular periods when not engaged in watching for food. It seems reasonable to suppose that in climates where the spiders are in a torpid state they would fasten their doors during this period.

tirely during the day. By reference to the young trap-door spiders it will be seen that -l\ 4-.syjmo.s'?t,s' works just about as well in day as at night.

Neni of Nidivalvata marxiL The first one of this species which I found was taken Jan. 2, 1886, and which I have formerly mentioned as making in captivity a " folding door." In tearing up some moss I observed a tube in the bottom of which was the spider. Whatever there was at the upper end of the tube was destroyed in removing the moss, so that I have not had an opportunity to observe the door to the nest where the spider makes its nest in a patch of moss. I have found several nests of this species by gathering moss. In all there were what appeared to be branches just above the surface of the p:round at the base of the moss. These I re- gard as avenues in which the spider would search, or lie in wait, for ants.

In captivity this spider made a very interesting nest with folding doors (See figs. 17 and 18 Plate IV) and I believe it is with some such arrangement that it closes its tube in a state of nature, for the spider makes use of it in catching its prey, as will be described in the food habits of this species. This kind of a duor, I believe, has never before been seen or described, and adds one to the different types of nests which Mr. Mop;i^^rid?>^e has described and named."" The v\<A\t name for this. type should be "double door," but as Mr. Mog- gridge has used that name for a nest which has two doors, one at the upper end of the tube and another some distance below at the opening of a branch in the main tube, it cannot be applied to this one. So I have called this new type the folding (loornesf, from the manner in which the door opens and shuts.

This species begins the excavation of its tube by parting the earth from a central point with its anterior legs and palpi turning around at the same time so as to push the earth on all sides. It works with exceeding rapidity, and in this re- spect is in strong contrast with the members of the genus PacJiylomr.rus, though the young ones of that genus work more rapidly than the older ones. When beginning the nest in a patch of moss the spider will dive down in the moss and begin turning rapidly in all directions, at t!ie same time spinning threads to fasten together the pieces of

moss around and over it. I have watched four diFfcrent ones make the nest, two beginning in moss which I had placed over the earth, and two beginning in soil. Two of these I had make a nest several times, and thus' far every one has first entirely closed the entrance to the tube by building a sort of dome above it. Later, in one case a week, cutting through this and making the folding door.' Usually while a.t work near tlie surface of the earth it will burrow out in different directions and elevate the surface of the earth. This I think is partly for the purpose of provid- ing a place to put the earth which it excavates from the lower portion of the tube as I have seen these filled up; and in one specimen, after the tube was about 2 cm. deep I ob- served the same habit of digging and cementing to the edge of the tube, as observed in the case of P</chf/fo)ncru.'i cinih/- voriiH and ^.-f^pinosus. This individual made the dome by carrying up three sides regularly until it had completely covered the entrance. Usually in making the dome earth is placed on and about the i^d^g^:! of the tube, occasionally ap- plying viscid liquid and spinning threads over it. Then the spider would, with its anterior legs and palpi pull the edge over the tube. This operation would l^e repeatetl until tlie dome was complete," When moss is convenient the door is made almost entirely of moss and silk ; each door is a sur- face of a half circle, is hung by a semicircular liinge, and the two meet, when closed, in a straight line over the middle of the hole, as shown in fig. 18, Plate IV. Every night (I ob-

served one in my room for tliree months) the spider would throw open its doors as shown in fig. 17, Plate IV and in the morning close them. If I opened the door during the day time the spider would invariably come up and close it, but never immediately, and never did it offer to catch the door and resist its opening. When members of this genus build their nest under stones, as they sometimes do, if the stone is elevated from the earth in one place the spider builds the tube above ground to the under surface of the stone, and here makes some sort of door, I have never been able to see just what, but probably very much like the ones made in captivity. A longitudinal section of one of these nests which I found under a stone is shown in fig. 11, Plate IV, the sur- face of the ground at a and the mouth of the tube at b. On turning over the stone I saw what I thought was the cocoon of a moth, from Avhich the insect had escaped at the upper end. I picked it up, and discovered the tube which I found about 12 inches deep, with the spider' at the bottom. This nest, perhaps inappropriately, I have called the hrdl dunr nest, because of the enlargement just within the entrance. This I consider would be of advantage to the spider in managing the door while catching an ant. The portion above ground was made of loam and leaf mold cemented with vis- cid liquid and lined on the inside with silk. So far as I have observed, the members of this genus line only that portion of the nest with silk which is liable to cave in near the upper portion of the tube.'^

Nest of MyrmekiapJdlafoUata.

The nest of this species is not constant in type, and shows widei variation in different individuals than any of those thus far described ; but when taken in connection with the food habit of the species there does not seem to be a very great departure from a common type.

The first individual was collected March 13, '86 by my- self. In collecting specimens of ants and their root feeding " cows " (Aphides) which they were protecting through the winter, I found a trap-door on turning over a stone. The tube I traced down about 14 inches, when I came upon and struck the spider off at one side. In doing so I broke off a

' Nidivalvatn angustnta.

'^ I have observed the same thing with Myrinekiaphila foliata.

leg and palpus so that the spider died the next day. At the time I thought the spider must have underground galleries in which it hunted for ants similar to the galleries in the moss of the nest of iV^/f//iT//i/Y//a marxii. But since finding the nests of other individuals I think there must have been a branch from the main tube with a trap door, and the soil being so full of rocks I failed to find it.

The second individual I collected on the morning of Apr. 6, '86, while digging into a side hill with a southern expos- ure for white ants (7Vrme9 ^r/r/p'-s). Discovering a tube I traced it until I found at one side a trap door opening into a short branch. In this I found a fine specimen of trap-door spider. The nest I concluded belonged to the type called by Mr. Moggridge, *' Double door branched nest," but dif- fers from that in having a cork door instead of a wafer door. I did not see the door at the end of the main tube, it there was one, as the soil was very loose and rocky, and every trace would have been destroyed before finding the main tube.

The third individual was collected in the afternoon of the same day, by one of the students, D. E. AVoodley. The tube ran under a stone, a trap-door was at the upper end, but the branch and second door was not seen. Mr. Wood- ley said, however, that it might have escaped his notice as the tube was not traced out very clearly.

The fourth individual I collected Apr. 6. On turning over a stone I saw what is represented in fig. 16, Plate IV, except that the trap door was closed, and the spider was in the tube a short distance below it. The space above the trap door is a portion of an ant's nest, h is the entrance from the surface of the earth ; a, «, is a broad hall-way leading off into galler- ies on the side. The spider had come down at h, undoubt- edly during the night while the ants were quiet, unconscious of the purpose cf their terrible enemy, dug the hole in the center of this hall-uay, and covered it with a trap-door be- fore the ants were stirring at the break of day. The soil was in a good condition for tracing out the tube, which I did very carefully and found neither branch nor second door, so that this nest was of the type si mjle cork (h)<n\tuil>r(nK'h('(l nest .

The fifth I collected on the same day and not more than 10 feet distant. Turning over a stone I saw a tube which ran down one of the perpendicular sides of the hole, in which the rock fitted, then along the bottom to near the cen- ter of where the stone lay. Here it disappeared taking a

40 JOURNAL OF THE

perpendicular direction again. I ran a straw down this tube and felt the movements of the spider. The spider would not seize the straw, as they sometimes will, and soon I could no longer feel the movements. I theii dug carefully around the tube, and at the depth of about ten inches struck the spider, splitting open its caput. This happened because the spider was in the branch : when I first ran the straw into the tubes she was in the main tube, and probably being frighten- ed ran into the branch and caught hold of the door. This confirms what Mr. Moggridge believes to be the case with spiders making a double door branched nest, that when an enemy succeeds in getting entrance to the main tube the spider will run into the bnmch.' This nest is represented in fig. 15, Plate IV. Though the tube is represented nearly natural size the length is much fore-shortened. The space represented by the dotted lines <i and l> was 10 inches for each. The spider was found at h ; the cork door can be seen at c.

Another specimen was found, about which, unfortunately, I have no record or recollection, except that it was collected sometime during the spring. This, though I have not given it a careful examination I believe to belong to the same species. I left it in the possession of Dr. Geo. Marx, at Washington.

The specimen collected Apr. 6, I placed in a jar of earth to see what kind of a nest it made in captivity. For several days it showed no signs of working. Finally I found it bur- ied in the earth much as J/idltxflccfd- nuirx'n is, when having just completed the dome over the tube, and from the appear- ance of things I think the burrow was started, and the dome made in the same way as in the case of that species. The next day in place of the dome, in which there was no moss, was a perfect cork door with an abundance of moss in it. The spider had evidently cleared away the dome, which was made of earth and silk, and made the door of new material.

When I lifted up this door the spider would catch hold of it. In a few days I found this door fastened down and that end of the tube filled with earth for a distance of 5 cm. The tube extended in a circuitous direction for 10 cm. or more where it came to the surface and was closed by another nicely fitting trap-door: I think the spider was alarmed at

'Harvesting Ants and Trap-Door Spiders.

ELISHA MITCHELL SCIENTIFIC SOCIETY. 41

the discovery of her nest, and attempted by this strategy to deceive her enemy. If the jar of earth had been more capac- ious, and a longer time given the spider, she might have made a branch and second door.

Food liahifs. I have not yei had an opportunity of mak- ing very extensive observations on the food habits of these species, and cannot say that each one is confined to the in- sect for which I am certain it lias a special fondness as an article ofdiet. Of the speci es of /'ac/u/lonicrns my observa- tions have been confined to 'P. carftblvortis. I have already stated the fondness which this speeies has for carabid beetles, and though killing several ants and flies did not use them for food. During July, while at Ithaca, N. Y., I fed several carabid beetles to a 7^. cir-foloorus which I had alive. June 20, I placed a TtiTo-sfichnJi 1 uciihlo nilus\ Say, in the bottle con- taining the nest of the spider. During the night the spider came out of the nest, caugt the beetle, ate it and ejected the hard parts from the nest. July 1st, it disposed of a 'Pterjst'i- r./ius Sat/i\ Brulle. June 29 it ate a beetle of the genus ChhviiiiiH. At another time it ate three good sized beetles of the genus Chhi^nius in one night.

The observatiion which I made on iVidiuaJvahi Afarxii in captivity are very interesting. I noticed that at night the spider would throw its doors wide open'' as shown in fig. 17, Plate IV. One evening I placed several in the jar containing the nest. When an ant approached so near the door as to send communication to the spider of its presence, the spider sprang to the entrance, caught a door with the anterior legs

' I am iariebted to Prof J. A. Comst jck for the identitication of the species of beetles.

He says that on one occasion a nest which apparently had no oritice was buried in a box of earth; subsequently the uibe was observed with a wide open mouth, and again was closed the following morning. The spider probably opens the doors at night to watch lor food, and closes them in the morning as doei iV. marxii.

42 JOURNAL OF THE

on either side, and pulled them nearly together, so that there was just space enough left for it to see the ant when it crossed the opening. When this happened, the spider threw the doors wide open, caught the ant, and in the twinkling of an eye had dropped back to the bottom of the tube with its game. This I saw repeated several times during the months of Jan- uary and P\^bruary. At one time I placed a large cricket in the jar. The spider made several attempts to capture it but was not strong enough. It would probably eat crickets when fortunate enough to catch one. I think also that it would eat small carabid beetles, for I found several in the moss where I collected the spider. I have found the remains of ants in the nests.

I hav^e made no observations on Mf/DnrkiapIuJn/o/uf.'n in captivity, but from the location of their nests it is quite evident that the members of this species are extremely fond ofants, and seek to build their nests either directly in an ants nest or in close proximity to it. I think in some cases it is intended that the main tube shall be used as a passage for ants, so that by coming out of the branch the spider can capture its food, for it is certain in these which I have ob- served that the external door is either wanting or old and in a neglected condition, while the door at the branch is kept well repaired. If I am correct in this conclusion it would account for the apparent variation noticed in the kind of nest built by this species. In the nest represented in fig. i6, Plate IV, the entrance b, and^the landing ((, a, of the ants' nest answers for the main tube of the spider, and only the one tube and trap-door is required for the use of the spider.'

DESCRIPTIONS.

Prefatory Note. It is not surprising that in a collection of some forty specimens there would be found several species, nor that a large number of these would prove to be new and undescribed forms, where so little attention has been given to spiders in general, and especially those of the order Territelarice, as has been given in America.

It has been a great pleasure to me to observe the nests and habits of so many of these creatures, which by their solitary and secluded life generally escape our observation. It has seemed necessary, that, in connection with interesting descriptions of their nests, architectural and food habits, these forms should be described and named. So interested have I become during the past year in the work of N. M. Hentz, that it would have given me more pleasure to find a specimen described by him than to find a new form. I feel sure that I have found one of his species, and possibly one other related species. I undertook the work of description with great reluctance, and have found it to be no small task. But my labors have been greatly lessened and I have been sensibly encouraged by the kindness of Dr. George Marx, of Washington, Prof J. H. Emerton and Samuel Henshaw, of Boston. Dr, Marx loaned me works from his private library, Prof Emerton placed for my study his excellent collection of Arachnological publications, and specimens for compari- son, which are now in the Mass. Inst. Tech., and showed me further kindness in directing me to the most useful works in the Library of the Boston Natural History Society. Mr. Henshaw also aided me in the same way and gave me the use of the specimens of Territelarice which are in the Museum of the Society.

I have also found works in the Boston Public Library which have aided me.

In the value of generic and specific characters I have been

the present case it is very important, as well as interesting, to conclude with som certainty that differences of type in the tubular ne^ts of the spiders Mr. Mcgti ridge has observed so closely and accurately, are joined to Well marked specific differences etc. "Harvesting Ants and Trap- Door Spiders, Supplement p 301." Later, Cambridge doubts such close union of specific character and architectural habit, for he finds nests of Atypufi piceus varying greatly in construction. (Annals of Nat. Hist. 1878, 5th series, Vol. 1, p. 107.) From nests made in captivity, I know that Pachyhmerus hirris 'and Nidivalvnta anguslata make different nests according as the environments change.

guided by those adopted by Anton Ausserer\ and the Rev. O. P. Cambridge', who have given considerable study to members of the Territelarice.

I have followed the classification adopted by Ausserer in his Beitraege zur Keiintidss dtr l^rritelaricB.

I subjoin, for clearness, a brief synopsis of his Classifica- tion.

Suborder Territdarice. This was divided by Thorell into 3 families, as follows *

2, lung sacs Catadisoid(s.

4, luner sacks,

a. AYithout spint) erets Liphistoidice'

b. With spinnerets TheraphosoidcB ^

The family Theraphosoidae, Thorell, is further divided into three subfamilies as follows :

Maxillge well broadened at the base, palpi inserted laterally, . Atypinae Thorell Maxillae little broadened at base, palpi inserted laterally

Eriodontinse Ausserer. Maxillffi not broadened at base, palpi inserted on the end,

Theraphosinae Thorell.

The Theraphosoidae are then further divided into two groups, based on the relative elevation of the caput above the throax.

a. Caput well elevated, ^picephoM'

b. Caput not much elevated, Tapinocephali.

In specific descriptions I have endeavored to not repeat characters which seem at present generic, so that in most cases it will require both the generic and specific characters to identify a single species ; for this reason I have given the characters of the genus Tachylomertcs, established by Ausserer.

are crowded. Eyes can be better described by speaking of them as X>e- ing in three groups ; the anti-centrals a diameter or less distant and sit- uated at the top and on sides of the hill ; on each side of these, not far separated is a group of three eyes forming a crescent with the concavity toward the midd e group; the eyes in this group nearly or quite touch each other. Fig 8, PI. V, represents the eyes as seen from the Iront at an angle of 45^ to a plane parallel with the base of the ceph'x

With this view the ant- and pott-laterals form a trapezium, base at post laterals one-fourth larger than opposite side; height about one- third of base, post centrals slightly in front of base of trapezium. Ant- laterals comparativtly large; others varying in relative size in different fcpecies, and it may be found that the relative position varies also as in Pachylomerus. Maxillae extended in front, but not so much as in Eriodon. Fig. 10 represents a maxilla showing insertion of palpus. Labium triangular, distal end rounded, longer than broad at iDase. Mandibles strongly kneed in front of pprpendicular clypeus.

About half or less than half as long as ceph'x , br )ad and deep, armed with a compar.itively strong fang ; the inner edge only of furrow for re- ception of fang arme I with terth ; upper and inner edges of anterior half armed with short spines, which also extend part way around base of fang.

Legs 4, 1, 3, 2. 4, 1, 3. 3, or 4, 1, 2, 3 ; palpi long. 3 tarsal claws. Claw of palpus unarmed. Abdomen short oval. Spinnerets 4, the upper pair long and slender.

Inner edge only of groove for reception of fang armed with short teeth; Iront of mandible, on the inside of the insertion offmg < rawn out into a three cornered toothed pr jection, much as in Pa':hylomerus, but a little smaller ; short teth along anterior half of inner upper eJge of mandibles, and few at base of fang. Abdomen elongate, cylindrical, tapering gently to each end. Spinnerets 4, upper pair medium size and length.

I have been somewhat in doubt about placing this genus

in the subfamily Eriodontuiae, as it has some affinities with

members of the subfamily Theyaphosince, division JEpice-

phali. But I think, after a comparison of the maxillae, with

those of Cteniza, Nemesia, and Eiui/pelma, some species of

which have a prolongation of the inner distal end, that the

character of the maxillae would place it in the subfamily

Eriodontuiae. If, however, it should prove to belong to the

Theraphosinae, it would constitute a genus related with,

Aepycephalus, Cteniza^ Cytocarenum^ and CyrtaucJienius, in the

ELISHA MITCHELL SCIENTIFIC SOCIETY. 47

group Aepycephali. It can, however, be separated easily from these genera by the following characters/

Aepyeephahis. ' Head high and somewhat pointed, ceph'x broad as long, side e}es form a trap-zium, lip broad as long, etc."

Vteniza "Side eyes from a trapeziimi. Lip somi what three cornered, spinnerets short ami thick Abdomen great, eggforme 1, etc."

Cyrlocfirenum. ' Ceph'x as m ( ^e7ai:a ; but head broader in front. Eyes occupy whole breadth of head, a'^dom ;n and spinnerets as in Cienua, etc."

Ci/r(auchenhis. "Foim of Ceph'x, ana position ol eyes as in Oyrioca- rertLtn^ maadibits nut drawn int) a point, etc."

As the nesting and food habits singularly resemble those of members of the genus Nemesia, and the form of the abdo- men also, it might be confounded with that genus, which be- longs to the group of TherapJiosinae called Tajn/ioccpludr^ as Nemesiai, as being related to the genera above mentioned represents the passage from the Aepycephali to the Tapino- cephalL The generic characters given by Ausserer*'' however easily distinguished it.

In addition to the generic chiracters are the following specihc charac- t-TS Anterior ceotr il eyes'* situate 1 from each other aboui t)ne diameter. Posterior lateral eyes a little larger than the ant-centrals. Post-centrals slightly angulated a little smaller ihan the ant-centials, each one about a diim^iter distant from the correspondinij: post lateral, and situated a very litle cephalad of the base of rectangle bounding the lateral eye?. Ant centrals on point of hill higher than tbe others. Ant-laterals lowest; th^se and the post-laterals situated at bnse of the low hill for the eyes.

P. carolinensis Hentz, was one of those to which he refers. I think he was right in placing it in this genus, but for the relative position of the eyes, aud some slight difference in the form of the labium there should be allowed some varia- tion in generic character, which he undoubtedly would have done, had he the opportunity to see the specimens.

This specimen I am convinced is the same as the o-'C describ d by Hentz as Mygale carolinensis. The description is very imperfect, and I take this ( pportu' ity of mMkiog it a liiile more compl' te. and • a-y to ident fy. Hjs description is as follows : ' Brownish, very gh^ssy ; cep- hal thorax with :wo slii^ht impressions near the base ; abd« men black- ish, not glossy; third joint of the third pair of I gs very short and crooked; feet 4, 1. 3, 2." Tbe spinal armature is the S'unp as in P cara- bivorus,hut the ceph'x and arrangement ot eyes are quite distinct. Ceph'x longer in proportion to m idth than in P. carabivorus, 10 mm. x 8 mm. in th's specimen. U-shaped depression situated more than two-thirds the distance from anterior margin of caput, making caput larger in pro- portion. In the curve f the U shaped depression, theri is scarcely any depression ; a very faintly depres.-ed line, which is quite readily seen because it is very dark, connects the two well marked depressions at the anterior ends of the U. As Hentz's specimen was a small one, these de- pressions would be smaller than in the specimen I have. Had it been a well marked U-shaped depression, he would have noted it, as he has in the case of May gale trancata.^

Caput caudal of eyes slightly elevated, making the slope quite steep.

Kadial depressions distinct, straight. Base of ceph'x 4 mm; angles not sharply defined; lateral edge from posterior angle to point of g latest breadth curved, with convexity ou; ward, fig. 2, pi.

Eyes. Ant- and post-laterals form a trapezium as in P. carahivorvs, but the ant centrals are situate don a line hallway between the base of the trapezi im and the Of posite side ; the pnst-laterals and cenirals forma curved Ime with convexiiy caudad, instead ■ f a straight line as in P. carahivorvs.

Sternum as broad as long, 5 mm., broadest part one third from caudal end.

M}j<jnle .solMltiolifi.^ Hentz : I am inclined to think, is the male of this species. The depressions in the ceph'x are similar, the difference in the lengths of the 2d and 3rd pair of legs is not of much specific importance in many species. The depressions on the abdomen are just what will appear in any of these species, when the abdomen becomes small for want of food, or after the depositing of eggs. In nearly all specimens either one, two, or three, or more pair of cir- cular depressions can be seen. When the abdomen shrinks the space between the depressed dots of each pair becomes depressed in the form of a rectangle as seen in Hentz's {\gurQ of Mj/'/alr solsfitifilis. The difference in color of the two is not of specific importance, for the young of /\ mrahiv- orns have a brow^nish ceph'x, the old a glossy black, and

when transferred to alcohol, this soon changes to brown.

Sternum nearly as broad as long, distinctly angled between articula- tions of coxa?. Labium shorter than broad at base, nearly triangular, separated from sternum by a furrow.

SOME NEW SALTS OF CAMPHORIC ACID.

I. H. MANNING.

Although this acid has been known for over one hundred years, comparatively few of its salts have been prepared and studied. The present work was undertaken with a view of extending this list, but was interrupted before very many additions could be made.

The camphoric acid was prepared, according to the direc- tions of Wreden, by dissolving 150 grams of camphor in 2 litres of nitric acid, sp. gr., 1.27, and heating the solution 50 hours on the water bath. The liquid was then satuated with sodium carbonate, filtered, neutralized with hydrochloric

acid, and the separated camphoric acid purified by crys- tallizing from water. The yield was about the same as that obtained by Wreden, when great care was exercised in the purification by crystallizing fi'om water. The pure crystals gave the melting point \y6°c. (uncorrected). A ten percent, solution of caustic potash was saturated with camphoric acid and the solution of potassium camphorate so obtained was used in preparing the other compounds.

Manganese Camphorate. When a few drops of potassium camphorate were added to a nearly saturated solution of manganese sulphate in a small watch-glass, no precipitate was formed until it had been heated on the water-bath. A white amorphous precipitate was then gotten, which was easily soluble in cold water. This could always be repre- cipitated on heating. In preparing the salt on a larger scale the mixture of potassium camphorate and manganese sulphate was heated to precipitation and the precipitate well washed with hot water. The precipitate was then dried at 100°. If exposed in the moist condition it showed browning. There was a slight discoloration even when rapidly dried. At 150° decomposition was very slight; at 200° it was marked. When some of the purified manga- nese camphorate was dissolved in water and evaporated over sulphuric acid a crust of the salt was obtained, but no crystal.

As it was very difficult to wash away all of the potassium camphorate the low results are probably due to the presence of the same as an impurity.

Chromium Camphorate. On adding potassium campho- rate to a solution of chromium sulphate a heavy precipitate of a biuish-green color is formed. This is not very soluble and can be thoroughly washed with cold water. It can be dried at ioo°c. losing all water at this temperature. Before reach- ing 150° slow decomposition sets in.

Ferric Camphorate. A strong solution of ferric chloride was precipitated with potassium camphorate, a bulky yel- lowish precipitate was formed, quite insoluble in water and hence easily washed. This gave on drying at ioo° a buft- yellow powder. An analysis of this powder gave the per- centage of iron as 19.34. The calculated percentage for F^2 (^10 H,4 OJs is 15.86, This powder was then probably a subcamphorate.

DECOMPOSITION OF POTASSIUM CYANIDE.

I. n. MANNIJIG.

Under the head of "Condensation of hydrocyanic acid" (Berichteder, d. chem. Ges. 18,1875) von der Pfordten dis- cusses the discoloration produced in solutions of potassium cyanide by the addition of free acids, or of certain salts, or by simple heating the cyanide alone. This phenomenon was examined and studied to a certain extent by Mr. Wilkes in the first number of our journal (p. 19.) Herr von der Pfordten speaks of the decomposition of the cyanide on heat- ing some hours in a test-tube placed in a water bath, as being due "probably to the long continued action of the carbon dioxide of the air." That this could not be the case was shown by Mr. Wilkes, who proved that the decomposition took place in the cold with all carbon dioxide carefully excluded.

The following experiment were undertaken to test th^ conclusion of Mr. Wilkes:

I. A saturated or nearly saturated solution of pure po- tassium cyanide was placed in a tube which was then sealed. Only a very nimute amount of carbon dioxide could have been present, yet the various changes of color were observed and after some weeks the liquid had become black and a blackish deposit had formed.

ELISHA MITCHELL SCIENTIFIC SOCIETY- 55

2. A similarly prepared tube was placed in boiling water; within five minutes a change to brownish-red was noticed, and the color lapidly darkened with the exposure,

3. A similarly prepared tube was fitted with cork and tubes, and while it was in the boiling water carbon dioxide was introduced. The changes were noticed very much as in experiment 2; apparently they were slightly delayed rather than hastened.

4. Into a tube prepared as in 3, hydrogen was passed in a rapid continuous stream. The changes were greatly delayed and no very deep discoloration was obtained.

5. If experiment 3 is so reversed that the carban dioxide is passed above a cold solution of the cyanide, giving oppor- tunity for its absorption, the change of color is rapid and deep.

From these experiments the conclusion can be drawn that though carbon dioxide hastens the decomposition of the cyanide, as any free acid would do, yet it is not essential for this decomposition. Chem. Laboratory, U. N. C.

LEAD CHLOE^SULPHO-CYANIDE.

R G. GRISSOM.

This new compound of lead can be easily prepared by acting on lead chloride with a strong solution of potassium sulpho-cyanide. Freshly precipitated and recry.stallized lead chloride was covered with a solution of potassium sulpho-cyanide in excess, and allowed to stand for several days. The liquid was then poured off and the residue treated several times with boiling water until all was dis- solved. This fractional solution was carried out to separate, if possible, substances of different solubility. The fractions rapidly deposited crops of crystals on cooling, but examina- tion under the microscope showed that these crystals were identical in crystalline form.

Analyses were made as follows :

.6220 gram, of subs-ance gave 5730 gram Pb SO, or 68.57 per ct Pb 1.0280 't » " '•' .7047 " " 0168.55 " " "

For chlorine and sulphocyanic acid 1.0700 grammes of

the substance was dissolved in water and precipitated with

silver nitrate. This was filtered and treated with strong

nitric acid thus oxidizing the sulpho-cyanide. After dilution

it was again filtered. The silver chloride was burned and

the sulphuric acid determined in the filtrate in the usual

way.

The formula for the compound then is PbCl^. Pb(CNSX. There is no water of crystalHzation and the substance can be he.ited to 150° without decomposition.

The solution poured off from the original lead chlor- sulpho-cyanide yielded mainly crystals of potassium chloride, together with some unchanged potassium sulpho-cyanide. The potassium sulpho-cyanide used was freshly prepared and purified by frequent recrystallization.

It is proposed to pursue farther the study of these double compounds of lead in the laboratory here. Chem. Laboratory, U. N. C.

SOLUBILITY OF ALUMIN'A. IN SULPHURIC ACID.

R G GRTSSOM.

Ordinary commercial alumina is not very easily acted on by sulphuric acid, and this solubility varies very decidedly with the strength of the acid. The following experiments were undertaken to determine at what concentration the acid has the most powerful solvent action.

The sulphuric acid used contained 95.25 per ct. H, SO,. Ten grams of alumina were put in a 200 c. c. flask, and the mixture of sulphuric acid and water (cold) poured upon it. A series of such flasks were heated to 30° for one hour. The contents were then largely diluted and filtered as rapidly as possible into looo c. c. flasks. The alumina was then deter- mined in duplicate, using 25 c. c. for each determination.

In the last column Nos. i, 4, 6, 8 and 11, only were re- peated and in the first four cases 10.8 c. c. acid were used, as this amount suited better the weight of alumina taken and the size of the flask. These experiments of course do not determined the absolute solubility of alumina in sulphuric acid. The temperature and length of exposure are both fac- tors in the solution. They serve to show soley to what extent it is advisable to dilute the acid in order to bring about the greatest solvent action. The best ratio of dilution seems to be 1:5 or 1:6.

ANALYSIS OF WATER FROM THE ARTESIAN WELL AT

DURHA]VI, N. 0.

As this is the only deep artesian well in this State, it seemed of interest to have an analysis of the mineral matter held in solution by its water. A carefully drawn sample of this water was therefore analized. The .sample was drawn during the summer of 1885, about five gallons being sealed in a new and clean demijohn and sent to this laboratory, under the direction of Mr. J. S. Carr.

The analysis resulted as follows :

struck. A sixty pound charge of dynamite was exploded in the hope of increasing the supply of water and by this the well was blocked up to within 528 feet of the surface. At- tempts at drilling through these obstructions failed, and the explosion of an additional ten pound charge of dynamite brought about no good results. An iron casing was there- fore let down to this depth, and the water analized was pumped from the 528 feet well.

One cargo of 500 tons Roncador Island Phosphate Rock was brought into Wil- mington in February 1885, but the venture was not success- ful, and no more has been brought.

The value of these products can not be stated exactly, but will be very nearly given by the following figures:

1,400 tons Ground Rock 9.00 12,600

23,802 " Fertilizers valued at - ^437,846

It must, however be noted here that some of the companies buy acid Phosphate of North Carolina make, mix it with cotton-seed meal or other ammoniate and sell it as Guano. It is difficult to say exactly how much acid phosphate is thus counted twice, first as acid phosphate, the company selling it as such, and then by the purchaser as Guano after it has been dry mixed with some ammoniate. But there is reason for believing that this would not exceed 1,500 tons of the acid phosphate, corresponding to about 2,500 tons guano. A fair allowance would be 1,500 tons to be subtracted from the guano out-put. The preceding table would then stand corrected as follows :

12,402 tons Guano less 1,500 tons —

10,902 tons Guano at - $23.00 ;^250,746

The 1,400 tons Ground Rock is not counted twice as it is North Carolina Phosphate Rock, Phosphate Conglomerate, etc., raised in the State, and sold as "fine ground " without being acidulated or ammoniated.

By reference to the table of production it will be seen that two companies make a speciality of " fine ground " Rock, French Bros at Rocky Point, Pender county, and the North Carolina Phosphate Company at Raleigh.

French Bros, have been in the business for several years, mining and grinding their own rock from contiguous de- posits. The rock is a phosphatic conglomerate, a mass of phosphatic pebbles and nodules in a cement of carbonate of lime. It is burnt in kilns, screened, and the residue ground. This residue may contain :

Phosphate of Lime - - 20.34 per cent. Lime, as oxide and hydrate 37.52 per cent.

(For further information as to this see under "General Ob- servations.")

Owing to insufficient machinery this company has not been able to place as much of their product on the market as they expect to do before long. The ground rock has a good reputation as a fertilizer.

The North Carolina Phosphate Company at Raleigh uses this rock also, obtaining it from Castle Hayne near Rocky Point They have a very complete mill, with a Foster crusher, and two Frisbee-Lucop grinders, and are doing an increasing business, with a daily capacity of thirty tons.

Besides these two companies there are none that use North Carolina rock.

THE PRESENT OUTLOOK IN NORTH CAROLINA.

Opinions vary. Some think the prospect fair, others are inclined to take rather despondent views.

Fertilizers have declined in price, and the $500 tax is not popular. There has been little or no mining of the regular North Carolina Phosphate Rock (containing 20-22 per cent. Phosphoric acid), for the reason that it lies in 'pockets' some- what widely separated, and the topography of the region is unfavorable for cheap mining. As long as Charleston, S. C Rock guaranteed to run 55 per cent. Bone Phosphate (25,19 per cent. Phosphoric acid) can be bought f. o. b. for $$.$0 to $6.50, there is but little prospect of the North Carolina Rock coming mto market in any quantity.

The first systematic investigation of this Rock was made by W. B. Phillips in September, 1883, at the request of the Navassa Guano Company. In his report to that company, published in pamphlet form (" North Carolina Phosphates October, 1883") he took the ground that the steepness of the slopes on the sides of most of the little streams where the rock occurs would necessitate an excessive amount of dig- ging, with proportional increase of expense, which the low grade of the rock would not repay. In march 1884, appeared the Report of the Experiment Station on North Carolina Phosphates, and since that time numerous references have been made to the matter in the publications of the Station, and of the Agricultural Department.

While the rock makes an excellent quality of acid Phos- phate it remains to be seen whether it can compete with Charleston Rock. So far it has not competed, for the reason that none of it has been offered. As to how soon, if at all, it will be offered.is a very obscure question, and one which time, and it may be a good deal of it, alone can answer. As to the other raw materials for the manufacture of fertilizers, viz : fish-Hcrcqj and cotton .seed meal as nitrogenous matter, pyrites as source of sulphuric acid, and hones, the following may be said :

FISH, OIL, AND SCRAP MILLS,

There are seven (7) in the State, three (3) of fair capacity, and four (4) small. P^mployment is given from April to November, to about 400 men, and the yearly value of the oil and scrap is about ;$ 150,000.

64 JOURNAL OF THE

The amount of North Carolina fish-scrap bought by the Navassa Guano Company in two years, ending February 5, 1885, was about 3,500 bags (140 tons), and they buy most of the scrap made in the State. This will give 1,700 bags (75 tons) per annum, w^hich is perhaps rather less than the real production. The true figures will fall not far short of lOO tons. Good scrap should yield 10 per cent, ammonia on 10 per cent, water. The account w^ill stand.

One hundred tons fish scrap lO per cent., a ;^2.50 per unit, ;^2500. About one-third (fA,) of this is made at the mouth of the Cape Fear River, and the other two-thirds on Pam- lico Sound, around Beaufort. The industry might be greatly enlarged, as there is always a good market for the scrap.

There are nine in the State, with a total capacity in seed of 200 tons daily. A ton (2000 lbs.) of seed should yield 800 pounds of cake. The cake is worth $2.50 per unit of Ammonia, and should run 8.5 per cent.

It is not know what proportion of the cake made goes into fertilizers, probably not above 4,000 tons. The product of two average size mills (the Acme and Goldsboro) is almost entirely used in this way.

PYRITE3.

None mined for sulphuric acid. All the acid used in the manufacture of the fertilizers is made from Sicily Sulphur.

BONES.

Bones are collected, but only in a small way. There is at Salem a small mill for grinding bones, and the Navassa Guano Company buys them from local dealers in small lots. The total quantity is hardly above lOO tons per annum, and so we have lOO tons Bones a ;$io, ;^ 1,000.

MARL.

The use of marl is local, and confined almost entirely to the Eastern part of the State. Very little, if any, is shipped by rail, each neighborhood using what is convenient, and easily transported by wagons. This is to be regretted, as the heavy clay soils of the middle part of the State would respond very readily to such an applicatiou.

GENERAL OBSERVATIONS.

The most marked feature of the fertilizer trade in North Carolina in 1886, was the increased demand for fine ground

phosphate rock. The new mill at Raleigh was built to sup- ply this demand, and the steady growth of the sales is an indication of the esteem in which the product is held.

An analysis of the article made at the Experiment Station is as follows:

Analysis of Ground North Carolina Phosphate Rock :

' Bone Phosphate - - 1 1. 16 per cent. Carbonate of Lime - - 64.26 per cent. Magnesia - - - 0.81 per cent.

Potash - - - - 0.40 per cent. Water - - - . - 1.39 per cent.

The fine ground rock offered by French Bros, is of a somewhat higher grade. An analysis of their best grade is as follows :

' Phosphate of Lime - - 20.34 per cent

Carbonate of Lime - -

Lime as Oxide and Hydrate - 37-52 per cent

Oxides oflron and aluminum, and loss 5.65 percent

This analysis represents the composition of the residue from burning and screening.

The composition before burning and screening is as follows :

' Phosphate of Lime - - 16.42 per cent.

Carbonate of Lime - - ' - 54.71 percent.

Lime as oxide and hydrate

Oxides oflron and Aluminum, and loss 3.91 percent.

The burning and screening separates the phosphatic nodules from the cement of carbonate of lime and converts this last into lime oxide and hydrate. All three of these articles are growing in favor with the farmers. The utiliza- tion of raw ground rock in the preparation of home-made manures, is one of the reasons why the price of acid phos- phate and guano has declined. Extra inducements in the shape of lower prices have now to be offered since the farmer has discovered that he can buy a good article for nearly 50 per cent, less than he has been accustomed to pay.

A SKETCH OF PROFESSOR WASHINGTON CARUTHERS KERR, M. A., D. Ph.

A Lecture before the Mitchell Society, at the University of North Carolina, January 34, 1887, by J. A. Holmes.

Mr. President and Gentlemen:

The life and work of Professor Kerr is a theme which needs no introduction before members of this society. Probably but few of those here present knew him personally, but in one sense all knew him. He knew North Carolina better than the people of North Carolina knew him; and yet he was quite widely known, both at home and amoug; scientific circles abroad. In travelino: recently through some of the nooks and corners of this State I have been surprised at times to hear him spoken of where I least expected it; and I know that his fellow-geologists in this country have placed a high estimate on his character and on his scientific work.

We may be sure of this much at any rate: that wherever in the State there is located a mine of importance, or other valua- ble mineral deposit of any kind, a fine water-power, valuable tracts of timber land, or interesting geological formations — wherever there has been, during these past twenty years, a man who souu;:ht information concerniim: the natural resources and material prosperity of North Carolina — there J*rofessor Kerr's

2 JOUJRXAL OF THE

name is a familiar one, and there, especially, during the two years and more since his death, there has been a realization of the fact that the important place he occupied among the people of the State is now vacant.

Professor Kerr was in birth, in education (in part) and in his life work closely identified with this State; and, as far as I am aware, he is almost the only native-born North Carolinian who has at yet attained a position of eminence in the ranks of sci- ence. Of the few others belonging to these ranks who have worked in the State, Professors Olmsted and ^litchell were natives of Connecticut, Dr. Von Schweinitz of Pennsylvania, and Drs. Curtis and Emmons of Massachusetts.

Washino-ton Caruthers Kerr was born in the Alamance reo:ion of Guilford county, N. C, May 24, 1827, and died in Asheville, Auo;ust 9, 1885. His ancestors were amon<r the sturdy Scotch- Irish families who came into this State from time to time about a century ago, and who have been important factors in the growth of several portions of North ("arolina. His father, William M. Kerr, was a farmer of small means. His mother, Euphence B. Doak, was a woman of marked characteristics, and is said to have possessed a mechanical talent unusually well developed. They had six children, of whom the subject of the present sketch was the third. Both parents died early in life, leaving their young children with no fortune save such early training and education as they had been able to give them at home.

Young Washington Caruthers, thus early thrown upon his owai resources, soon developed the qualities he exhibited so prominently throughout his whole career — energy, perseverance, decision of character, a thirst for knowledge, and deep piety.

After the death of his parents he was taken in charge by the Rev. Dr. Caruthers, a Presbyterian minister, author of ^^Revo- lutionary Incidents" in North Carolina, and widely and favor- ably known in the State for his piety and learning.

Dr. Caruthers had been long the pastor and friend of the Kerr family, and the boy he thus adopted had been named in his honor. In addition to his labors as a minister he conducted

ELISHA MITCHELL SCIENTIFIC SOCIETY. 3

a school at or near Greensboro, where he lived, and largely under his instruction young Kerr was ])repared to enter the Univer- sity— which lie did in 1847, as a sophomore. He was gradu- ated in 1850, taking highest honors in his class.

I cannot dwell long upon Professor Kerr^s University life, though, in some respects, no part of his career is more deserv- ing of consideration. It does not apj)car that he exhibited at this time any special tendencies in the direction of his later })ro- fessional work, but we must remember that in 1847, chemistry, geology and natural history were all taught from text-books, in the class-room, by one man, who })erforme{l other duties besides. There was then no brino;ino; the student face to face with nature; no inducement, no opportunity for original investigation by the student; no awakening of interest in such work. But in gen- eral scholarship in the University and in the debates of his literary society he was without a superior among his classmates. He was a hard-working, careful student, full of energy and ambition, and always ready with speech and pen.

His University life was not, however, in every respect a pleas- ant one. It was a struggle against poverty, and he was proud and sensitive. Here again, however, the necessary aid was at hand ; the University made no charge for his tuition, and the Dialectic Society, of which he was a member, made him its beneficiary, and paid all necessary living expenses during his connection with the institution. Some years after graduation he returned to the University and brou^rht his wife with him, and showing her the places familiar to him as a student, he took her to a certain spot on a street in Chapel Plill, and told her how once Dr. Mitchell (then the Bursar) approached him there and reminded him of some small payment due the University. '^The Doctor went on,'' he said, "and there I stood, and where under all God's skv I could raise five dollars I did not know. The agony and humiliation were too great, and T resolved to quit college and give up all hope of an education."

Fortunately for us, and for himself, he did not go, but such an experience he never forgot. To help other people in like

4 JOURNAL OF THE

straits^ was in after life one of the ways in w^hich he expressed his remembrance. And nearlv thirty vears after his graduation, when the University was in need of funds, and its friends were asked to contribute money for tlie repairs of the buihlings, Professor Kerr was one of the few who remembered how much it had done for him, and contributed largely for a man of his limited means. And I may here mention another incident in the history of his University life which illustrates the rip-id honesty of the man. The sum granted annually by the Dialectic Society for the support of its beneficiaries, just enough to supply the necessaries of life, was always given and accepted as a free and willing gift. Young Kerr found that by cutting his wood and attending to his fires himself, and by practicing economy in other ways, he could live on less than the amount set apart for his support, and returned the surplus to the Society. The only case of the kind on record, so far as I am aware.

During the first year after his graduation, young Kerr taught school at Williamston, Martin county, N. C. Shortly after this he was elected to a professorship in Marshall University, Texas, which he accepted; but after a brief stay there he resigned his position to accept an appointment (1852) as computer in the office of the Nautical Almanac, then located in Cambridge, Mass. Prof Kerr's connection with the Nautical Almanac (from June, 1852, to January, 1857), and his consequent life at Cambridge, marks an important period in his 'life. On the Almanac he was principally employed in making astronomical computations, computing the moon's right ascension and declination, its culmi- nation over the meridian at Washington, and the lunar distances; he also computed the eclipses for the year 1857.

But this work on the Nautical Almanac, though Professor Kerr's source of support (and yielding him an income more than sufficient fi)r this), wjis by no means the most important feature of his life in Cambridge. Here, for the first time, he was in an atmosphere of active scientific work. Here he met, as instruct- ors or associates, Agassiz, Pierce, Davis, Lovering, Horsford, Eustis, Guvot, and many others. Here he bea^un his own work

in science. Here he made acquaintances and formed friendships that yielded pleasure, encouragement and assistance during the remainder of his life. During the earlier part of his stay here (1853) he was happily married to Miss Emma Hall, of Iredell county, N. C.

The work on the Nautical Almanac did not require all of his time, and during the years 1853-'4 and 1854-'5 he is recorded as a member of the Lawrence Scientific School, studying geology, mathematics and engineering. During this time (1853-'56) he also studied zoolooi;v under Professor Ai^-assiz, botanv under Professor Gray, and chemistrv under Professor Horsford.

These years at Cambridge were among the happiest of Pro- fessor Kerr's life. In after years his face always brio;htened when he referred to them. Naturally enough, Agassiz was the central figure amon<»: those whom he admired and under whom he worked. He often alluded to his first lesson in o;eoloii:y — Agassiz's giving him a handful of sand and asking him to report on its contents — and other incidents connected with his great teacher. He was just beginning, under Agassiz, a piece of original research in connection with some newly-discovered species of fossil fishes, wliich was interrupted by his being offered, and accepting, in February, 1856, the t)rofessorship of chemistry and geology at Davidson College, in this State. How- ever, he remained at Cambridge a year after this, continuing his connection with the Nautical Almanac (until January 13, 1857), and during his spare time preparing himself more fully for his future work at Davidson College, where he begun the duties of his professorship early in the year 1857.

In speaking of Professor Kerr's work at Davidson, I cannot do better than quote from a letter on this subject written by a gentleman who was one of his students at the college during 1858 and '59, and whose name would be a sufficient guarantee of the accuracy of his statements. He says of Professor Kerr: "He was an ardent student, an enthusiastic and successful teacher, and it seemed almost by contagion his students would catch something of his spirit. He had little patience with dull-

6 JOURXAL OF THE

ness — none with idleness — and his class-room was dreaded by the indolent or careless. It was the deli<i:ht of others. He was a successfnl experimenter, and every operation in chemistry was beautifully illustrated, with the imperfect appliances at his com- mand. He taught by text-books, with explanatory and supple- mental lectures. He was alwavs addino: to the museum, and gathering about him specimens, maps and sections to illustrate his teaching in geology and mineralogy. We used to call him ^ Steam Engine,' instead of Kerr, such was his promptness to titne and rapid motion."

Another of his students of 1857 and ^^8, whose statement may be relied upon, says: ^^ Professor Kerr brought new life to the college, and was the most industrious teacher I have ever known. He awakened thought and investigation. My class never did so hard work for any other teacher." He occasionally took his students on field excursions in geolog^^ During the summer months of 1861 he led a party of them through a con- siderable portion of the mountain region of North Carolina, making extensive geological and topographical observations.

Professor Kerr's connection with Davidson College continued from 1856 to July, 1865 (the date of his resignation), but his active work there ceased three years prior to this latter date. Soon after the beginning of the civil war there was a falling off in the income of the college and in the number of students. Professor Kerr requested, and was granted (July, 1862), a leave of absence until such time as he was needed, and in the latter part of 1862 he became chemist and superintendent to the Meck- lenburg Salt Company, whose works were located at Mt. Pleas- ant, near Charleston, S. C.

This position he continued to hold until April, 1864, when the works were destroyed or abandoned. The company worked profitably during its short existence, and Professor Kerr's services were highly commended. While engaged in the work he introduced several improvements in the process of manufacture of salt, chiefly in the construction of better chim- neys, which operated a larger number of salt-pans; in placing

ELISHA MITCHELL SCIENTIFIC SOCIETY. 7

the pans in positions better suited to more extensive work with less handling, and in the pumping apparatus for ti'ansferring the brine from one pan to another. These improvements were so eflFective that their introduction reduced the cost for wood one- half, and also greatly lessened other necessary expenses.

After tlie destruction of the salt works Professor Kerr returned to North Carolina and was appointed State Geologist of North Carolina by Governor Vance in 1864. This office he held — quoting his own words — '^during tiie last year of the war, nominally y and icithout pay, and with special instructions to look after certain chemical and mineral manufactures in which the people of the State were vitally interested." Under circum- stances like these there was, of course, neither time nor money for the ordinary work of a geological survey, and the time of the nominal State Geologist was fully occupied in advising and directing in connection with the manufacture of salt, saltpeter, copperas, sulphur, sulphuric acid, medicinal extracts from plants, and various other substances needed for purposes of w^ar or home consumption. And subsequent to this came the closing scenes of the war, when all was confusion and disorganization, and even the nominal geological survey disappeared from view until April, 1866, when it was revived and Professor Kerr re-appointed State Geologist by Governor Worth.

The work with which the name of Professor Kerr is to be permanently associated is that done in connection with the Geo- logical Survey of North Carolina. He begun this work in his mature maidiood, and devoted to it the best years of his life. His more important scientific work was done during this time, and as far as these are known to me, all his scientific papers were ])ublishcd during his connection with the survey. From the time of his appointment as State Geologist (April, 1866), he contimied his connection with the survey without interruption until August, 1882, when he resigned to accept the position of geologist on the United States Geological Survey. And when declining healtii compelled him (in September, 1883) to resign this latter position, he returned to North Carolina, and, in part.

8 JOURNAL OF THE

renewed his connection with the State Survey, hoping that he might be able to complete certain unfinished work. But the end came and found his hope unrealized.

In endeavoring to understand clearly the character and extent of the work undertaken bv Professor Kerr in the organization and prosecution of his survey, it will be well for us to review briefly the work done and that left undone by his predecessors. As to the survey by Professors Olmsted and Mitchell (1824-':^8), at so late a date as 1866, it was of interest mainly from an his- torical stand-point, as being the first geological survey under- taken by any one of the States. It located a few of the valuable mineral deposits and approximately some of the geological for- mations, but as a scientific survev it could liardlv be considered more than a preliminary geological reconnolsscmce. After the close of this survey (1828), Professor Mitchell continued for sev- eral years to make explorations in different portions of the State at his own expense, and the general results he published in 1842 in a small volume'^ accompanied by a geological map of the State. This geological map of the State was the first published, and none other appeared until 1875. It reflected credit upon its author, but was uot found suflicnentlv accurate in detail to be of any great value, in the work of the survey under Professor Kerr.

Dr. Emmons, while State Geologist (1851-'63), did a large amount of valuable work, especially in connection with the geology and agriculture (including the swamp lands) of the eastern region, and the geology, mining and agriculture of the middle region; and he made several geological excursions into the western portion of the State. At the breaking out of the civil war, he had nearly completed a geological map of the State, a map of the coal fields, manuscript reports on the agriculture of the middle section, and a partial report on the general resources of the western section, of the State. But in the tur-

moil and excitement of the war all of these, together with all the manuscript and field notes of the survey, were lost or destroyed, and the industrial enterprises inaugurated or stimu- lated by the ten years' existence of the survey were checked or permanently suspended.

As the tangible results, then, of the Emmons survey, we have his five published reports relating to the geology and agriculture of the eastern section (including; the swamp lands), and the geology and mining of the "Midland Counties" as far west as the Catawba river — these and, practically, nothing more.

Organized under the same law. Professor Kerr's survey had in view the same general purposes as the Emmons survey which had preceded it, viz., investigations into the general geology and natural history and the natural resources of the State. Such being the case, it was Professor Kerr's plan to determine what of the objects had been most fully accomplished during the administration of Dr. Emmons, and as far as possible to avoid iinnecessar}' repetition in supplementing the work already done. But he found that in a study of the general geology of the State, and in making a new geological map, it was necessary to go over the entire State again. In the eastern region much still remained to be done in determining the relative age of the deposits, and in the middle and western regions, with the improved meth(Kls of lithological study, it was found necessary to have the rocks of both regions carefully examined.

But l)efore this work in general geology and the making of a reliable geological map could be successfully prosecuted, it was necessary that the survey be in possession of a topographical map of greater accuracy thati was then to be had ; and for several years no small part of Professor Kerr's time was necessarily given up to this topographical work. In connection with this work he found it necessary to determine the elevation, lati- tude and longitude of quite a number of places in the middle and western regions of the State — his work in this direction supplementing that done by Professor Guyot and the United States Coast and Geodetic Survey.

10 JOURNAL OF THE

Also in the departments of mining and paleontology much remained to be done. In connection with the departments of agriculture it was necessary to make arrangements for the analyses of numerous soils and marls; in meteorology, stations Avere to be organized in many parts of the State, and each sup- plied with instruments, for the purpose of determining, as far as possible, the climatology of the State. Indeed, but two branches of the survey, viz., zoology and botany, had been worked up (and these by Dr. Curtis) w^th a thoroughness that could be con- sidered sufficient for existing purposes.

The new features undertaken bv Professor Kerr in connection with the survey were the investigation into the topograpliy, the climatology, water-power, mineralogy and lithology. Of work alreadv undertaken bv Professor Emmons he endeavored to continue that relating to agriculture, ore deposits, general geology and paleontology.

Wiien it is remembered that all the work outlined above was to be undertaken with an appropriation of "not more than five thousand dollars per annum," it will be understood that the sur- vey must necessarily have been organized on an economical basis, and the work prosecuted at a disadvantage. And such indeed was the case.

When in 1866, Professor Kerr was appointed State Geologist, he did not bring to the work of the survey an extended profes- sional experience; nor may we consider him at that time in any high degree a trained specialist. He at once, however, devoted himself to the task of organizing the work of the survey, in all its departments, and in accordance w^ith the terras of the law and the interests of the State. He associated with himself such specialists as Cope, Conrad, Genth, Julien and others, and placed in their hands for examination the collections belonging to their respective departments.

So great was the variety of work the survey was authorized to undertake that, with the small appropriation at its disposal, it was often necessary that the Geologist should undertake in person investigations of a widely different character. This was

ELISHA MITCHELL SCIENTIFIC SOCIETY. 11

especially the case in connection with the topographical work of the survey. There was in 1866 no even approximately accurate map of the western part of the State u})()n which could be laid down the data for a geological map. During almost the entire period of the existence of the survey Professor Kerr, in making his geological excursions, combined topographical and geological work. And in this way he became quite proficient in the detec- tion of geological structure as exhibited in the topography of the region.

In some cases his topographic observations were only approxi- mate, taken with a pocket compass, pocket level, or aneroid barometer; but as a rule these instruments were used only to fill in details after the more important measurements had been taken by means of more accurate instruments. During several seasons, early in his connection with the survey, Professor Kerr devoted a considerable portion of his time to topographic work (or geological and topographical work combined) in the mountain region.

These numerous topographic observations, made by himself and his assistants, bore fruit in 1882, when he published the new State Map, to be used as a base for the geological map.

In connection with this work, he examined all the accessible records of the surveys of railroads, rivers, canals. State and county boundary lines, and of the United States Coast and Geodetic Survey, within the limits of the State; and com- binino; the results of these examinations w^th those of his own and his assistants' work in the field, he produced a map which in point of accuracy is incomparably in advance of any map of the State that preceded it; and maps published subsequent to its date will be indebted to it more than they are wont to admit. Its preparation cost its author no small part of fifteen years of labor.

Professor Kerr was a rapid worker in the field, and at no time could this fact be observed to better advantage than during one of his horseback trips through the mountain region of the State, which he seemed to enjoy so much. After his appointment as

12 JOURNAL OF THE

State Geologist lie dev^oted himself first to these western coun- tieSj whieli had been more or less neglected by Dr. Emmons. He traveled, mainly in the saddle, 1,700 miles over mountain roads and mountains without roads, within less than four* months; and in two seasons (parts of 1866 and 1867) traveled on horseback a distance of more than 4,000 miles.

It was during this rapid reconnoissance of the mountain region that he became acquainted with many of the problems which the structure and drainage of this region present. The drain- age, especially, interested him, and he recognized what appears to be the true explanation of the origin of its prominent fea- tures, viz., the existence of the Blue Ridge as the original water- divide, from the crest of which, at approximately right angles to its course, flowed the accumulated waters of the larger streams; the subsequent slow and gradual elevation of the Smoky Mountains and the intervening plateau region on the west, through which the rivers eroded their YnWeys, pari passu , as the elevation progressed. The smaller streams tributary to these rivers as a rule have their general course at right angles to the latter, and parallel to the mountain range and to the out- crop of the more or less nearly vertical strata, into the upturned edges of the less durable layers, of which they have carved their channels. During these and subsequent years he collected a large amount of material with a view to writing a special report on the drainage and physical structure and history of this region; but the press of other duties, and later, declining health, prevented its preparation.

Durins; his entire connection with the survev Professor Kerr spent a considerable portion of his time in field explorations. He traveled a good deal along the lines of railroads, on hand-cars or on foot, leaving the railroad at intervals to examine soils, rocks, mines, &c. At other times he traveled in a buggy or spring wagon, prepared especially for his purpose, or in hilly regions on horseback. In studying the geology of the eastern region of the State, along the water courses, he traveled by boat.

111 one or the other of these wavs he traversed in different directions every connty in the State — some of them many times. Occasionally he delivered a lecture in the town through which he passed. Generally as he traveled he collected for the State Museum specimens of rocks, soils, minerals, ores, marls, woods, and other products. His field note-books are full of notes con- cerning especially the rocks, soils and forests of the regions through which he passed.

There were no permanent assistants employed on the survey, and in view of the limited appropriation at his disposal, Pro- fessor Kerr adopted the plan of doing in person the general work of the survey, and engaging the services of specialists or general assistants when these were needed. He attended to the official correspondence, without the aid of either clerk or amanu- ensis; and no one w^ho has not occupied a somewhat similar position can realize the amount of labor and time this demanded.

His correspondence concerning the mineral, mining and other economic interests of the State was quite large, and with men in many parts of the United States and Europe. His correspond- ence with citizens of this State was large and covered almost every subject. In the same mail one might see the following assortment of letters, addressed to the State Geologist: One ask- ing for instructions as to the best method of developing or sell- ing a gold mine; another asking for similar information about a deposit of mica; another (or several) accompanying specimens of rocks, minerals or ores, asking for a complete analysis and instructions for development or selling the property; and per- haps a dozen others asking for information about the gold depos- its, the water-power, and the climate of the State, the practica- bility of a railroad passing through this or that region, the im- provement of worn-out lands, as to the best methods of raising silk-worms, making vinegar, medicine for a sick horse, and sub- jects not more germain.

In endeavoring t(^ estimate the results of Professor Kerr's work we may confine our attention to the period of his connection witli the survey, whether we have for consideration the material

14 JOURNAL OF THE

benefits resulting to the people of the State, growing out of his work as State Geologist, or his contributions to science. The former of these cannot now be estimated with accuracy, but we may safely say that his work has been an im])ortant factor in the recent material growth of the State.

In connection w^ith the mining interests, during the past twenty years, several millions of dollars have been brought into the State; and while exercising an important influence in connec- tion with this, the survey has encouraged a more judicious investment of home ca})ital, and has done an important work in preventing numerous investments where the undertaking would have proved a failure and the money invested lost.

The agricultural interests of the State received at all times Professor Kerr's earnest attention. He made numerous analv- ses of soils and marls, and he did all in his power to stimulate the improvement of worn-out soils by the use of marls, lime and other fertilizers, and by other methods. The inspection and analvses of commercial fertilizers, inaugurated and continued for several years by him, and later carried on by the Experiment Station, has proved of incalculable benefit to farmers in every portion of the State; and Professor Kerr, together with the hon- ored President of this University and a few others, was instru- mental in the establishment of the Department of Agriculture and the Agricultural Experiment Station. He inaugurated the movement of a few years ago looking to the increase in supply of food fishes in the streams of the State; and (as stated already) he established and kept in existence for a time a series of meteor- ological stations in different portions of the State. He originated the silk-raisino; movement in North Carolina — a result of his visit to the Vienna Exposition. He measured the water-power of all the important rivers of the State.

In the matter of advertising the State's resources by making collective exhibits at great expositions, Professor Kerr believed that much benefit would result to the State, and subsequent developments have proved that he was correct. In 1873, though the Legislature of the State declined to appropriate

ELISHA MITCHELL SCIENTIFIC SOCIETY. 15

money for the purpose, he, together with two or three otlier patriotic citizens, contributed of their own private funds suffi- cient to enable him to collect specimens illustrative of the State's resources, which he took to Vienna and exhibited at the Inter- national Exposition.

In connection with the Philadelphia Exposition of 1876, though the State again failed to make an appropriation for the purpose. Professor Kerr, out of the limited funds of the survey, made an exhibit of the building and ornamental stones of the State, which Avas commended for its excellence; and he remained at Philadelphia during much of the time of the Exposition as one of the judges. While there, under the direction of the Exposition authorities, he delivered an address on the history and resources of North Carolina, and did everything in his power, by way of distributing reports and circulars, and by per- sonal interviews, to direct the attention of capitalists to the State. Subsequently he was the leading spirit in making the North Carolina exhibit at the Atlanta Exposition (1881), and his pre- liminary work made the fine exhibits at Boston (1882) and New Orleans (1884) practicable undertakings.

The distribution of Professor Kerr's reports, and his official correspondence with persons in our own and other countries, have been doubtless of great service in the development of the State's resources; not only in importing capital, but also in educating the people of the State, thereby giving them a more intelligent understanding of the nature, extent and worth of their proper- ties.

The educational value of his work among the people of the State — accomplished through his reports, newspaper articles, cor- respondence, lectures, private talks, and the State Museum — has been of itself a matter of considerable importance.

Not least among his undertakings was the State Museum, at Raleigh. It was a part of his plan, from the time of his first connection with the survey, to bring together such series of specimens as would represent the general natural history and natural resources of the State. He used to say that he wanted

16 JOURNAL OF THE

to 'Mjriiig Xorth Carolina together in one building/' where she might be studied by specialists in science^ or by persons looking to an investment in the State, and where the people of the State might go and become familiar with her native wealth — vl plan full of promise; but, unfortunately Professor Kerr, had neither the time nor funds to enable him to carry it into full exe- cution. He collected from all parts of. the State a large amount of material, consisting mainly of specimens of rocks, minerals, fossils, soils, marls, agricultural products, woods, and others of miscellaneous character, but had not been able to arrange them fully up to the time when press of other work and declining health compelled him to give up all endeavor in this direction.

But it is impossible in a few statements to give an adequate conception of the extent and of the benefits, to the people of the State, of Professor Kerr's work^ — benefits that will continue to be felt during years to come. He begun his work at a time in the history of the State — just after the close of the civil war — when her industrial as well as her social condition was one of disorganization and suspension. It was his desire and aim to stimulate and encourage her material prosperity, and while favored with good health he gave himself up to this endeavor with a foresight, energy and devotion not often surpassed.

Among other results of general interest, it may be stated that Professor Kerr has left us a fairly good knowledge of the physi- cal structure and climatology of North Carolina and has mapped the outlines of the geological formations of the State much more fully and accurately than had been done before. Could he have lived a few years longer he would heve added materially to our knowledge in these directions. His scientific work was chiefly in physical geology, and though not extensive, it was sufficient to give him an enviable position among American geologists. Professor Dana savs of him, in the American Journal of Sci- ence for 1885 (xxx, p, 248): "He was an excellent observer in geology, and in his few publications brought out results of great interest. He was the first in the country to call attention to, and rightly explain, the unequal steepness in the opposite banks

of streams, where flowing through yielding deposits (Rep. Geol. N. Carolina, Vol. I, p. 9*); and the first to appreciate ade- quately and describe the action of frost in producing the deep movement and bedded arrangement of loose material on slopes (Am. Jour. Sci., Ill, xxi, 1881, p. 345t), the depth in North Carolina being such as to indicate, in his view, the unu- sual conditions of a Glacial era." In 1881 (Am. Jour. Sci., Ill, xxi, p. 216) he suggested the glacial origin of certain topographi- cal features of the hydrographic basins of rivers in the southern Appalachian region (North Carolina), but this does not appear to have met with general acceptance.

A full list of Professor Kerr's reports and more important scientific papers will be given in the bibliography, published in the Journal of the Society as an appendix to this sketch. Of his official reports, the two first were small reports of progress, published in 1867 and 1869, discussing mainly the general and economic geology of the part of the State west of the Cataw^ba river — especially the mountain region. The first of these con- tained also (Chapter III) a short general discussion of the ''Minerals of North Carolina," which was subsequently, in part or as a whole, several times republished by the State and pri- vate land agencies. A third small re[)ort was published in 1873, as an appendix to the report (Vol. I, 1875) then in press, which was an abstract of that report, intended for general and immediate distribution. This small report was subsequently revised and republished in 1879, under the title of a "Physio- graphical Description of North Carolina." The most impor- tant of his reports is that of 1875 (Geology of North Carolina, Vol. I), treating of the physical geography, general and eco- nomic geology of the State. This re})ort was offered to the Legislature in 1870, but its appearance was delayed until 1875, the Legislature having failed to make an aj)propriation for its publication. It was Professor Kerr's plan to prepare a second volume (Vol. II of his Pinal Report), to contain a more full

discussion of the general and economic geology of the State; and Chapter I of this volume, discussing the "Minerals and Mineral Localities of North Carolina/' was j)ublished by him in 1881; but press of other duties at that time, his resignation in 1882, in order to undertake the topographical and geological work on the Appalachian division of the United States Geologi- cal Survey, and his subsequent decline in health, all combined to interrupt the completion of this report. So much of it as relates to the economic geology of the State is now being pub- lished under my own direction. Three additional small reports of the survey were published by the State as public documents, viz., a Keport of Progress in 1873, a Report on the Expendi- tures of the Survey and a Report Concerning the Establisliment of a State Department of Agriculture, in 1877. In 1882, Pro- fessor Kerr published his new Map of North Carolina.

He was appointed special agent of the Tenth United States Census to report on the cotton production and general agricul- tural features of Virginia and North Carolina; and his sepa- rate reports on these States were published in Volume VI of the Census Reports (1884). He was an occasional contributor to the scientific journals of this country, and his more valuable contributions are to be found in the American Journal of Sci- ence, and in the Transaction of the American Institute of Min- ing Engineers. He wrote the article on North Carolina in the Encyclopaedia Britannica (9th Edition).

Professor Kerr was a member of several learned societies, in- cluding the American Institute of Mining Engineers, the American Philosophical Society of Philadelphia, and the Philo- sophical Society of Washington. He was also a Fellow of the American Association for the Advancement of Science. He was a member of, and during the years 1884-'85 was President of the Elisha Mitchell Scientific Society.

When in August, 1882, he was offered the position of geolo- gist on the United States Geological Survey, he accepted the appointment in the hope that he might be able to carry into execution a long cherished plan of making a more systematic

and thoroiigli study of the topoi^rapliy and theological structure of the Appahu-hlau re<>:ion. But in this disappointment awaited him. He had but fairly heirun the topoo;ra])liic work when, in vSepteniber, 1883, failing health necessitated his resignation.

The disease — catan-h of the digestive organs — which had for so long a time preyed u}>ou him, had now greatly weakened his svstcni. Dui-in*!' the two vears f »llowin<i: he was unable to do any active work. He spent the winters at Tampa, Floi'ida, and the summers in the mountain region of this State. It was dur- iuLT these stavs at Tam|)a that he made obsei-vations on the eocene deposits there, his notes on which were j)ul)lished subse- quent to his death, in the Journal of this Society (188o-'8(J).

Professor Kerr was through his whole life at the disadvan- ta2:e ordinarily attendant on a iihvsical oroanization to() frail for the work imposed upon it. He was of the sturdy and enduring Scotch-Irish I'ace, but there must have been a cross of some other blood which <»:ave him the verve and delicacv of luind and bodv that distinguished him, and that even in early \\i'(^ indicated him as one not likelv to see old aire. For tiu; last fifteen or twentv years the condition of his health was a constant source of anxi- ety to his friends and family. Still he would not succund), but clunu: to his woi'k, imi)elle(l and sustained bv nervous enerjxv alone, and undertaking additional labor even after it was plainly apparent that his day w;is over.

Many things dei)ressed him, many things irritated and hin- dered, which, if his j)hysi(pie had but been coarser and stronger, he would n(»t have felt. No memoir that means to do him fid! lustice should onu't to indicate; these characteristics, since bv them lie was often judged aixl mi-judged.

r^r<»m the time of his apj)oiiitiuent as State (Jeologist to the day of his death he spared himself no j)ains, no exertidU, no fatigue in lii> ai'dor for the development of" North ("ai'oliua, his anxiety to see her among the fbi'emost in the new raee set before the S(»uth. 'I'he State has never had a more genuinely and sagaciously publie-<pirited eiti/cn than he. But the times wei'c evil, and for several vears Prol'essor Keir shared the fate ol' all

20 JOURNAL OF THE

public officials who were endeavoring to adjust, to reconcile, and to go forward. His motives were misrepresented, his character assailed, his abilities questioned, his work maligned.

The effect of such an ordeal on a man of delicate nervous fibre and of refined feeling may easily be imagined; nor can it be wondered at that he was often impatient, often despondent, and often fairly unhino;ed bv the obstacles set in liis way. Almost every session of the State Legislature was a season of humiliation, and, as he himself expressed it, of "real torture^' to him. At the adjournment he would draw a long breath of relief, and say the incipient paralysis Imd passed off and he could go to work again and feel like a gentleman once more.

In his own house. Professor Kerr's hospitality was unbounded. Scientific visitors would sometimes remain with him weeks at a time. He thought it his duty to entertain strangers, and every public occasion in Raleigh filled his house with guests. He was a most interesting companion, animated, receptive, sympa- thetic, taking a vivid delight in conversation, and as ready to listen as to talk.

His belief in the outcome that there was in this State, in the great future that lay before her people, was com- mensurate with his knowledge of her natural resources. He knew^ them well and rated them justly, and was never so enthu- siastic, so vivid, so eloquent, as when dwelling on these advan- tages. In his death the State has met with an inestimable loss. In some respects he has lived ahead of his time. He was, in his own department of work, more widely and favorably known, and deservedly so, than any man the State has produced or the State University has graduated.

He was an exceedingly liberal man; a man of generous tem- per, and of large views not only, but open-handed to every call in State or Church, or private benevolence that his judgment approved. He was deeply religious, and always prominent, though in an unobtrusive way, in matters pertaining to his church. As a Christian gentleman, those who have known him best have admired him most. His heart was warm and gener-

ELISHA MITCHELL SCIENTIFIC SOCIETY. 21

ous, his mind was clear, active and progressive, his conscience keen and inflexible. He was honest in every sense of the word. There was nothing of policy in his thonght or action. On the contrary, he was frank and outspoken, at times even to a fault. He left his native State the better for his example and for the work that he did in her service. If he failed to do all he aspired to do, and was compelled to leave his task incouiplete, it was no more than an oft accompanying condition to human endeavor weighted by human frailties.

THE STUDY OF LOCAL FLORAS.

GERALD MacCARTHY, B. Sc.

Every State iu the Union has a flora more or less pecnliar to itself, and tliere is scarcely a county in any State wiiich has not its local rarities, found nowhere else.

Almost ev^ery community, too, has its botanical enthusiast, who is not infrequently of the tender sex. Useful work has been and is being done by these isolated observers. But because of the lack of organized effort, and of a clear apprehension of the end to be achieved by botanical study, a great deal of well- meant energy is misap{)lied and wasted.

The capital error of most amateurs and beginners in botany is the exaggerated opinion they entertain as to the value of the herbarium.

There is said to exist in Hindostau a sect of religious enthu- siasts who infest the high-roads by which travelers enter India for the purpose of ingratiating themselves into the confidence of strangers, wh(»m they then entice into some lonely spot and murder as a sacrifice to the goddess Kali.

We have among ourselves a class of scientific enthusiasts, worshippers of the mummy god Herbario, who with unwearied patience and tireless limb hound high-road and byway, bog and mountain ])eak, ever on the look-out for floral strangers, whom they ruthlessly sacrifice to the glue-and-paper deity.

To laboriously collect, dessicate, ])oison and mount plants on sheets of costly white ])aper, and then lay them away in a cabi- net probably never to be disturbed during the owner's life-time, may be good physical excercise, and is scarcely more straining upon the brain than whistling. But it is a question whether this is science. It certainly is not religion, nor yet common sense, both of which prescribe as the proper aim of the activity of a rational creature, "the greater glory of God and the im- provement of man's estate." It is probably true that a herba- 4

26 JOURNAL OF THE

riuraist now and then stumbles upon a useful fact, and in the aggregate, taking the whole country into account, these discov- eries amount to something; but that the discoveries are not com- mensurate with the enero^v absorbed is a matter that admits of no debate.

As far as the average student is concerned, the study of plant life may be rationally pursued for two purposes, namely: for the mental discipline it affords and for the useful information it furnishes bearing upon the aifairs of practical life. But the average student is usually content to study his plants only just so far as may be necessary to learn their names and proper places in the herbarium. This sort of information is certainly not practical, and as for the mental discipline it affords, after the student has once got the 'Mvcy'^ well under control, it prom- ises even less than whistling; for the whistler is often, greatly to his moral and spiritual welfare, kicked by men and bitten by dogs, whereas the herbariumist is too frequently the victim of the undiscriminating and hurtful praise of the vulgar. The only real use subserved by a collection of dried plants is that it enables nomenclators to compare one species with another so as to determine their relationship and position in the natural sys- tem; and as a pendant to this, to preserve typical specimens for the purpose of giving stability to botanical nomenclature. It is necessary that plants should have distinctive and well recognized names, so that they may be intellii^ently studied by diiferent botanists and generations of botanists. But the herbariumist works in a circle. He studies his plants for the purpose of learning their names, notwithstanding that nomenclators have already named them that they might be studied.

Gray, Chapman, Vasey and Watson have so thoroughly sys- tematized the nomenclature of American plants that very little now remains to be done in that line, and that little can be done only by botanists who have access to extensive museums and libraries, such as no private collector can hope to own. Isolated collectors can be of real service to the cause of science and human progress only by placing their services at the command

ELISHA MITCHELL SCIENTIFIC SOCIETY. 27

of the curators of some of the larger public aud semi-public herbaria, of which the country hn'^ already an ample supply.

The Gray herbarium at Cambridge, Mass., would alone be sufficient for all necessary purposes. Besides this, there are at the National Capital two large collections : one at the Depart- ment of Agriculture, of which Dr. George Vasey is curator; the other at the National Museum, in charge of Professor Lester F. Ward. These herbaria are public property and may be con- sulted in person by any student, or by letter addressed to the respective curators. As the value of such collections depends laigely upon their completeness, private collectors should take pride in making them as complete as possible by depositing with them all their more valuable typical specimens, and by collecting further under the intelligent direction of the curators.

But this kind of botany, though not to be despised, is not the most valuable work that the local botanist may do. He may, by observation aud experiment, seek to discover the useful aud noxious properties of the plants more or less peculiar to his locality; the environment most affected by particular species; the means by which they accomplish the fertilization of their ovules and the dispersion of their seeds; the effect of wet and dry, hot aud cold seasons upon plant growth ; the parasites they harbor, and many other interesting, useful and yet unsolved problems in plant physiology and pathology. A single student of this sort of botany may do more in a life-time to advance the cause of human progress than can be accomplished by the united labors of any number of herbariumists continued through all eternity.

Activity of whatever kind whicli subserves no useful purpose in regard to human welfare is a criminal abuse of the trust Humanity has reposed in each one to whom she has given the power of thinking and acting, that tliey might thereby smooth her pathway and accelerate her progress toward perfection. Viewed solely as a means of discij)lining the intellectual facul- ties, botany is unequalled by any other of the natural or i)hysi- cal sciences.

28 JOURNAL OF THE

Botany is pre-emineDtly the science of observation, and the observino; faculty is the most fundamental faculty of the mind. Observation supplies the solid foundation upon which all the higher faculties must rest, when they rest upon anythino^. With- out such a foundation, and the check a well disciplined observ- ing faculty places upon the imagination, the latter faculty is very apt to run away with the judgment. We daily see. often to our cost, how inherited instincts and developed prejudices so pervert judgment and reason that two men of equal respectability and mental calibre^ if they belong to different political faiths, will make diametrically opposite reports concerning the working of some law or set of circumstances.

As already remarked, neither for mental discipline nor for useful knowledge does the private herbarium subserve any use- ful purpose. But it would perhaps be over-sanguine to expect that a simple expostulation like tiiis will suffice to convert the present generation of herb-secreting botanists.

i^ccording to the famous law of Mr. Darwin, the modern herbariumist, while deluding himself with the fancy that he is doing something useful, is in reality merely gratifying a once useful instinct which has outlasted its function — an instinct inherited from a long line of herl)ivorous and nucivorous, pre- hensile-tailed ancestors.

Since, then, the private herbarium may not be done away with at a .stroke, some directions tending to shorten the time absorbed in the mechanical work of the herbarium may not be wholly out of place.

In the first place, good, .symmetrical and full-grown plants should be selected for specimens. Collect the whole plant — root and branch — when not over three feet high. When higher than this, that length, measurirjg downwards from the top, may be cut off; and in addition, a few inches of the stem with the leaves next the ground, and the root, .should be secured.

Of trees, flowering twigs, showing the bark as well as leaves and flowers, will suffice. A sharp knife to cut off twigs, a trowel to dig up roots, an air-tight tin box of convenient size,

and a pocket magnifier, are all the a|)})aratus necessary for field work. A good drying-press is two latticed fratnes 12Jxl8J inches. These can be made ont of a few laths by any one. The best drying paper is the soft felt paper used by builders and for placing under carpets. Common straw wrapping paper will, however, do very well. Pressure may be applied by means of a cord or trunk-strap passed around the package and pulled as tight as a good strong arm can do it — sixty pounds at first, and afterward one hundred pounds, is the proper pressure to apply. The jtackage thus compressed should be hung up in the sunshine and air, or placed near the kitchen stove. The paper must l)e changed every day for the first three days. After that the press may be left alone till the plants are entirely dry, which will take two or three days more. Plants should, when possible, be iden- tified and labelled before putting to press, but labelling may be done afterward. Under the usual routine, the next thing would be to soak the dried specimens in a solution of corrosive subli- mate, re-dry them, and then mount them on heavy white paper by means of gummed slips. But all this work may be well dis- })ensed with. Procure a supply of soft, uucalendared manilla paper in double sheets, size ll|^xl7J inches. Take four parts of white arsenic, five parts of washing soda; boil in thirty-five parts of clear rain-water for fifteen minutes, or until the solids are dissolved. Replace the water eva|)orate(l with water heated to boiling. Into this solution the manilla sheets are to be dipped, holding them by the open edge. It is best to keep two or three inches of the open edge un wetted, so that in turning over the leaves the fingers may not get l)urnt by the poison. The wet sheets are to be spread out in the sunshine to dry. Between the leaves of these poisoned sheets the plants with their labels are to be laid, but not attached. The labels had better be written on pretty thick card-l)oard so that they will not easily "dog's-ear." Arrange the species of each genera al})habetically and enclose the whole in a tliin jrenns cover in the iisual wav. Write on the lower left-hand corner the name and serial number of the genus, and the name of the natural order to which it belongs. Arrange

']0 JOURNAL OF THE

the genera of each family according to their serial numbers, and place them between two thick genus covers, opening into each other. Write on the lower left-hand corner of" the package the name and serial number of the natural order, and place around the whole a stout elastic band, or a piece of tape, to keep all snug and tight.

The packages thus made up, each containing the plants of one natural order only, or, if the order be too extensive, a part of an order, are to be laid away in pasteboard or other kind of boxes of sufficient size to receive the packages without compress- ing. It is best to have the boxes all of uniform depth. Those used in the herbarium of the United States National Museum are 12Jxl8Jx 6J inches. They are of stout pasteboard, cov- ered with black muslin. The cover comes off in the usual way; the front end is hinged at the bottom and falls down wdien the cover is lifted up, exposing tlie labelled ends of the enclosed packages. Each box has a brass ring fastened to the outside of the front end b} means of which it is readily pulled out of its pigeon-hole. Spaces for the name of owner and for the names of the natural orders inclosed are also provided. The names of the genera included may, if desired, be written or pasted on the iyiside of the hinged end. A small piece of naphthaline should be pinned in one corner of the box. The odor of this substance is very disagreeable to insects, and will prevent the female insect from entering to deposit her eggs. The boxes, arranged in regu- lar succession, may be kept on racks, in the cases usually employed, or as suits the fancy ; but so that any one box may be taken out and returned without disturbing the rest.

THE LIMITS OF THE SENSES.

F. P. VENABLE.

It is surely a profitable field of research, in this age of the credulity of science, to see what limits are set to the powers of investigation themselves. The error of believing all things within the grasp of natural science is, at least, as common as that of setting too narrow bounds to this ever-progressing branch of human knowledge. Of late several efforts have been made to determine how far man is capable of laying hold upon the secrets of the nature that environs him. To gather and sum up these results, together with whatever additional facts experiments have enabled us to learn, will lead to a clearer conception of our powers and of the boundaries of man's field of work.

We are broug-ht into communication with our environment bv means of five or more senses. Bv means of these senses onlv can we examine into the nature of that environment. In fact, it is throu":h them onlv that we are aware of the existence of such an environment. The settlement of the question as to how far-reach iuii: these senses mav be is rendered difficult bv the two facts: first, that they are highly susceptible of training, and hence we meet with them in different degrees of perfection in different individuals, and secondly, that by various appliances man has found it possible greatly to extend and amplify some of them, giving them wonderfully increased powers. It is not possible, then, to state that the end has been reached; that the particular organ of sense can never be trained to a higher degree of perfection, or that no improvement upon such appliance and instruments can ever be designed. AVe can at best but learn the limits of present knowledge together with the probabilities of further progress. Not only are the limits of the unaided senses to be pointed out, l)ut as well those of the instruments that aid or magnify them.

32 JOURNAL OF THE

Most importaut in tlie field of physical iDvestigation are the senses of taste, of smell, and of sight. The sense of touch may be very marvellously developed in some cases, especially where there is a deficiency in one or more of the other senses. This compensating power of nature is true of all the senses, and of course must be taken into account in any discussion of their bounds. The loss of one results in greatly increased acuteness of the others. What may be true of the sense in its normal or average condition would have to be greatly modified for it when thus abnormal. The limit found in the one case must be extended much farther in the other. It is highly probable that this increase of power in the remaining senses is chiefly the reward which Nature places upon increased training and that similar power can be attained without the loss of any of the senses by subjecting oneself to equally careful training. It is well known that the blind can easilv distinguish the nature of objects which they pass, even though at quite a distance from them. The test of touch is one of the earliest we apply from our infancy on, yet from its superficial nature it can solve but few of the problems and explain scarcely any of the mysteries which surround us.

Akin to the sense of touch is the temperature sense. It is not generally known, though researches at Upsala and Neissa and Baltimore have shown, that on our bodies we have spots capable only of sensations of heat, others capable only of cold, and between the two those capable of neither heat nor cold, but of pressure only. These spots have even been carefully mapped out. Thev are verv small and are easily exhausted. With all their sensitiveness, however, these spots are not capable of meas- uring heat very delicately. The sensations, too, are based on no fixed standard. The measurement of temperature by means of a thermometer without a degree marked upon it would be mere guess-work and niemory, and this is the case with this "tem- perature sense." Hence the frequent recurrence of phenomenal temperature, summer and winter, exceeding the bounds of the inemorv of the "oldest inhabitant." It is warm, it i>< cold, according as the preceding sensation was colder or warmer.

ELISHA MITCHELL SCIENTIFIC SOCIETY. 33

We must, then, to decide this matter of temperature, have recurrence to auxiliary appliances, these recording their results throuo-h the sense of si^ht. As achievements in this line we have a mercurial thermometer, reading to the one-thousandth part of a degree, the exceedingly delicate bolometer of Langley, and lastly Vernon Boys' modification of D'ArsonvaPs instru- ment, which he calls the Radiomicrometer. This last measures the one luindrcd-millionth of a degree. In the report of its exhibition before the Royal Society it is said to show the heat cast by a candle-flame on a half-penny piece 1,168 feet distant. This gives the present limit to our process of determining tempera- ture, and there is no reason for saying that this limit may not at some time be transcended.

The sense of hearing seems to reach its limits rather quickly. As, accord i no; to the theory of sound, heariu": is but the result of the beating of sound-waves upon apparatus placed within the ear, it does not lie far to infer that the bounds of hearing will be determined by the sensibility to the greater or less rapidity of the strokes. It is found that sounds with less than sixteen beats to the second and those with more than thirty-five thousand do not impress themselves upon the average ear. A wide scope, but still a decided limit, and we can let the fancy play at will among the "voiceless" sounds which must fill the world around us.

When we consider the sense of sight we find assistance from magnifying instruments very essential. The limit of the unaided sight is soon reached. If a line an inch long be cut into ten equal parts we can easily see each separate one. If divided into one hundred such parts they merge into one another, and it requires a clear vision to separate them. This separation is easily accomplished by the microscope, however. Yet when each one of these divisions is further divided into one thousand, or the whole line into one hundred thousand, even the microscope and light itself fails us, for at this point the waves of the light- rays interfere witli one another and the divisions, though sfiarp- cut, seem blui-red. So that the very force of nature which affects the organ of sight itself sets a limit to its usefulness.

34 JOURNAL OF THE

Just as the ear caD adapt Itself only to sounds having a lim- ited range of beats or wave-lengths, so the eye can receive impres- sions from those rays only which move within a limited range of velocity. Beyond the red rays of the solar spectrum are many, quite invisible to the eye because of the length of their waves and the slowness of their movement, yet readily detected by a thermometer or thermopile. And so beyond the blue are very many invisible rays, too rapid and short in their motion, which are revealed to us by means of sensitized paper and which can only be seen then in their photographs. There are rays of light, then, of which tiie eye takes no cognizance which have an impor- tant warming and life-giving part to play in nature. We are forced to recur to the thermometer and that valuable coadjutor in scientific research, the photographic apparatus, to detect and measure these for us. If we retain the old definition of lio-ht as the force of which we are sensible by means of the organs of sight, can we call those light-rays which do not affect the optic nerves, and if not light, what are they ?

Astronomers tell us that imperfections of instruments, impuri- ties and peculiarities of the atmosphere, limit the usefulness and the power of telescopes. Apparently not much more is hoped from the expensive and laborious enlarging of the glass lenses. No wonderful revelation is looked forward to. The limit in tin's line seems nearly reached.

In the spectroscope we have a wonderful and powerful instru- ment, and one from which much has been expected. One of the greatest workers with the spectroscope. Dr. Crookes, whose pains- taking patience seems almost marvellous, tells us that its vision extends almost to infinitesimal particles. Of sodium, for instance, we can detect the one fourteen hundred-thousandth part of a milligramme.

One would hardly suspect that the sense of smell was more delicate than that of sij^ht, vet the researches of Fischer and Penzoldt have shown that the nose is capable of detecting some substances with a delicacy two hundred and fifty times greater than the spectroscope. That is, without any external assistance,

ELISHA MITCHELL SCIENTIFIC SOCIETY. 35

it is more far-reaching into the realm of Nature's little things than the most powerful instrument devised to aid the eye. How infinitesimally small must be the particles which for years arise IVom the few grains in a box of musk, and yet the sense of smell can unerringly detect them. How tiny the particles of perfume rising fi'om some small flower and scenting the breezes for hours — that is, conferring fragrance upon many miles of air. Still how easily the delicate nostril detects the presence of the sweet fragrance.

This would seem to open up a new field of work for the ana- lyst, offering him most delicate assistance, and indeed Dr. Crookes suggests as much, but unfortunately, though so easily affected by some substances, the great majority of them do not affect the organ of smell at all, or in very slight degree, no matter in what quantity they may be used. So far as the quan- tity of matter is concerned, it is usually the case that the smell becomes less and less apparent as the quantity is increased, after a certain limit is reached. If too much ottar of roses or hydro- gen sul})hide be used, the sense of fragrance or of its opposite is largely lost.

Turning now to the sense of taste, the last of these senses to be investigated, I can find no reported experiments upon its delicacy. Apparently only a few approximate statements have been made with regard to one or two substances. I have with some care experimented upon this point with a few characteristic substances, utilizing the sense of taste of two persons so as to partly eliminate personal errors. Known weights of the sub- stances, dissolved in the pro})er solvent, were diluted until the taste was barely perceptible, a slight further dilution causing its disappearance. The results show the sense of taste much less delicate than that of smell. Of sugar, y^^Q-g- of a gramme barely tastes; of salt, j-^^; of acid (hydrochloric), xordo"? *^^ saccha- ^'•'^ 1000000^ ^i"^l ^f strychnine j^-^5___^ ^f .^ gramme gave barely a perceptible taste, and this was the greatest delicacy of taste, or persistency of taste, reached with the substances experi- mented upon. Tf we compare the delicacy of taste towards

36 JOURNAL OF THE

strychnine with the delicacy of the spectroscope towards sodium, we find the latter in the neighborhood of one hundred times stronger.

These, then, are the bounds of our senses, so far as can at present be determined. That they were unlimited was not to be expected. Yet when we see these limits there is no room for a feeling of disappointment that man cannot grasp everything. The field for his powers is almost infinitely vast as it is, and the only cause for discouragement lies in the sharp limit put to the attainment of knowledge by the short space of his working time.

THE ELEMENTS, HISTORICALLY CONSIDERED.

F. P. VENABLE.

According to the modern definition an element is the simplest form of matter. It cannot be further decomposed nor reduced. Other elements may be added to it and compounds formed, but nothing can be taken from it when in its elemental state. If it can be decomposed it ceases to be considered an element. Hence we can only state that such and such forms of matter are ele- ments, because at present no means of reducing them is known.

This is an interpretation which has gradually grown up. In earlier times the idea was ratlier that of the genesis of matter. This last has been a puzzle which man has long striven to solve, and not merely a vexed question of these modern days, as we, in our arrogant assumption of vast intellectual superiority, are ^pt to think. Dr. Gladstone, in his address befi)re the British Association, at its meeting of 1883, says: "In the childhood of the human race the question was eagerly put, ^By what process were all things made?'" Shoo King, the most esteemed of Chinese classics, comprises the Great Plan with nine divisions. The first division relates to five elements — water, fire, wood, metal, earth. And this idea of the genesis of matter is attached

ELISHA MITCHELL SCIENTIFIC S0CIE:TY. 37

I

to the word element down to a little more than a century ago, when in Macqiier's Dictionary of Chemi.stry — English Transla- tion, 1777 — we meet with the modern definition, worded as fol- lows :

"Those bodies are called elements which are so simple that they cannot by any known method be decomposed or even altered, and which also enter, as principal or constituent parts, into the combination of other bodies, which are therefore called compound bodies/' But he adds: "The bodies in which this simplicity has been observed are fire, air, water and the purest earths/'

In Table I, will be found the supposed primal elements at different periods, reaching as far back as history goes. It is but just to state that Dr. Crookes recognizes the insufficiency of data to support the theory of a primal element, and hardly does more than suggest "protyle" as an interesting possibility.

In Table II a list is given of those at present acknowledged to be elements, with the date of discovery and name of discov- erer. ^yith regard to the dates of discovery, it is interesting to note that nine were known in the earliest historic times, four more were discovered before the eighteenth century, fifteen dur- ing the eighteenth century, and forty during the nineteenth cen- tury.

The last thirty years of the eighteenth century form an espe- cial season of activity. Twelve out of the fifteen elements dis- covered during that century were discovered in those years. Taking the present century by decades we find that fourteen elements were discovered in the first, four in the second, seven in the third, five from fourth to sixth, inclusive, three in the seventh, five in the eighth, and two in the ninth. Davy with his discoveries made 1808 the most prolific year, but Wohler in 1828 runs him a close second.

As to nationality, Germany can claim the first rank with eiirhteen discovered elements. Euii^land comes next with seven- teen, France lays claim to eleven, and the discovery of the remainder is due mainlv to the labors of Scandinavians. It is

38

JOURNAL OF THE

strange that while other countries have elements named in their honor, England alone is without this distinction, notwithstand- ina: her sons have been so industrious and successful in their search.

Table III gives a list of the supposed elements discovered since the modern era of chemistry. It is difficult to make such a list complete, as mistakes and errors in science, as elsewhere, are very numerous, and this is in large measure a list of mis- takes. It can only be said of the present list that it is as com- |)lete as the literature at command would admit of. Wherever possible the dates when the errors were found out are also given.

The latter portion of the table cannot be called a list of errors. It represents new work, however, and that so recently completed that other workers have not as yet fully substantiated the results. When such confirmation is complete these "supposed elements" would have to be transferred to Table II.

With regard to dates and names in both of these last tables (II and III) one meets with some confusion and contradictory statements. This is especially true in Table II. The best authorities and evidence attainable have been followed.

EFFECT OF DECOMPOSING ORGANIC MATTER ON INSOLUBLE PHOSPHATE OF LIME.

F. B. DANCY

Some time ag;() I instituted a few rough ex])erinients with a view to a.scertainino; if the process of cleconi])o.sition »f organic matter, or the products of such decomposition, had any eifect on tri-calcic phosphate of lime in the way of converting it, or any part of it, into its soluble form. The first results were of such a character that the exj)eriments were not carried on to the extent originally contemplated, hut I thought it migiit be well to call attention to them as far a.> thev went.

For my samples I selected, first, a good specimen of ground bone, containing 40.01 per cent, phosphate of lime and 54.02 per cent, volatile-and-organic matter, and ground fine enough to pass a 60-mesh sieve. Next, I chose an especially pulverulent sample of South Carolina phosphate "floats," and then selected some good fish-scrap, ground to pass a 40-mesh sieve, and some excellent specimens of cotton seed meal, dried blood, and "am- monite," all ground to pass a 60-mesh sieve. In all these sam- ples I determined the per cent, of phosphate of lime and of volatile-and-organic matter. I then made four mixtures, con- sisting of fish-scrap and floats, cotton seed meal and floats, dried blood and floats and ammonite and floats, in such proportions by calculation that the content of volatile-and-organic matter in each should be the same as in the ground bone, namely, 54.02 per cent.

I then took 25 grammes of the ground bone and 25 grammes of each of the four mixtures, rubbed them up well with water in mortars, and transferred them to filters in funnels, let the water extract filter through, and then washed the contents of the filters with successive portions of water until my filtrates amounted to, I think, about a liter each. I then stopped the ends of the funnels with little stoppers and left the moist con- tents to rot at the ordinary temperature of the laboratory, w ith free access of air. During the process of the decomposition I kept the masses moist by additions of water from time to time, and, by stirring them, kept fresh portions turned up and exposed

to the air.

I found the per cents, of soluble phosphoric acid in my fine samples, just after mixing and before rotting (obtained in the filtrates just alluded to), to be:

TABLE I — BEFORE ROTTING.

1. Bone meal 0.1149 per cent. Soluble P2O5.

2. Fish and floats 0.1292

3. Meal and floats 0.0486 "

4. Blood and floats 0.0289 *'

5. Ammonite and floats 0.1537

ELIBHA MITCHELL SCIENTIFIC SOCIETY. 43

In seventeen days the n)ass of moist bone meal was thor- on«;lilv rotted, and a week later the other mixtures showed that they, too, were well decomposed throughout. The putrid smell from each of the five was highly offensive — alipost unbearable. I now leached out the soluble again with the same amount of water as at fir.>t. The filtration was exceedingly slow, requiring about six davs, so slowlv did the successive additions of water percolate through the putrid masses.

In my filtrates I determined the soluble phosphoric acid as before, and found it to be as follows:

'J'ABLE II AFTER ROTTING.

1. Bone meal 0.0G.34 per cent. Soluble PaOs.

2. Fish and floats 0.0894 " "

3. Meal and floats 0.1561 " " "

4. Blood and floats 0.(J969 "

5. Ammonite and floats 0.1052 " " "

The filtrates, reeking as they were with organic matter, pos- sessed a more or less opacity, and I w^as led to suspect that in the cases of 2, 3, 4 and 5 there might be some of the finer por- tions of the floats passed the filter. So I evaporated these four filtrates down, which cau.sed a separation and collection of the suspended matter, and filtered each into two parts, determining the phosphoric acid in each of the filtrates and residues thus obtained. The figures given in Table II are the sum of these two determinations in each case. In every case but 3 (that of the cotton seed meal) the phosphoric acid in the residue was in excess of that in the filtrate, tending to show that most of the phos})horic acid leached out from the rotted samples was mechanically carried through the filter rather than pas.sed in genuine solution. The cotton seed meal seems to have had most effect. But, granting that the whole of it was carried through in genuine solution, the per cent, is so sn)all as to show that little reliance can be placed on the decomposition of the organic matter with which our in.soluble phosphates are in contact as to rendering these pho>])hates soluble.

44 JOURNAL (3F THE

What assistance the soil may give should the decomposition take place there, or what aid the })Iant juices may lend to the end desired, must be determined by more elaborate experimenta- tion.

Had the per cent, of soluble phosphoric acid been considera- ble after the first rotting it was intended to carry on the rotting further and see the effect of prolonged decomposition, but as the effept brought about by thorough putridity was so insignificant it was concluded that further investigation would be a loss of time on these particular experiments.

PRELIMINARY CATALOGUE OF THE BIRDS OF NORTH CAROLINA, WITH NOTES ON SOME OF THE SPECIES.

GEORGE F. ATKINSON.

PREFACE.

Object of the catalogue. Previous to the work which was undertaken to prepare the present preliminary catalogue, very little systematic eifort had been made in the study of the birds to be found in the State of North Carolina. Of the earlier works mention should be made of Catesby's Natural History of the Carolinas;* but this work covered an extent of territory much larger than North Carolina, and included species which belong to an entirely distinct fauna.

*The Natural History of Carolina, Florida, aud the Bahama Islands, by Mark Catesby. 1771.

ELISHA MITCHELL SCIENTIFIC SOCIETY. 45

Beside the VVoodv Plants of North Carolina* and a cataloerne of the flowering plants and cryptogamsf of the State, the Rev. M. A. Curtis prepared for publication a "Description of the Quadrupeds'' and a ''Description of the Reptiles'' of Xorth Carolina. It is unfortunate that an appropriation was not made for the publication of these valuable reports; and still more so that the manuscript copies are probably lost, as frequent search has thus far failed to reveal their existence. In the letter! which recommends the publication of the above two reports Mr. Cur- tis says, "I have also in preparation, if desired, a 'Descrip- tion of the Birds of North Carolina.'" The extent of his work upon the birds of the State remains as yet unknown, whatever portions of it were completed being wrapped in the same obscurity which involves his work on the quadrupeds and rep- tiles.

The object of the present catalogue is the enumeration of the birds which liavc been observed and absolutely identified within the State since about 1880, though most of the work has been done since 1884 and 1885; together w^ith notes on their occur- rence, distribution, and nesting. The work is recognized as incomplete in that it is a preliminary catalogue. The hope that the publication now of the records of the work, so far as it has progressed, may stimulate a desire in resident North Carolinians in different parts of the State to collect material and record observations of the birds to be found within our State limits; and the knowledge that the present catalogue would not only convey some useful information, but serve as a convenient pamphlet for reference and check list, induces me to present it in its present imperfect form.

Material. The collection of material at Chapel Hill was begun by myself in January, 1886; and, assisted by some of my students in the laboratory, has been continued to the present time, though no collections were made during the summer and fall of 1886. University duties interfere greatly with collection of material during the time for transient visitors, but such time as has been practicable has been zealously devoted to the collec- tion and preservation of material for study and future reference. In all about 120 species have been observed and absolutely identified by myself at Chapel Hill; \Vl species have been pre- served. In December, 1887, I visited Beaufort and New Bern, examined the collections of Mrs. Geoffroy and Mr. A. Finer, at Beaufort, and that of Clark and Morgan at New Bern ; and also made some collections and observations in the vicinity of Beau- fort, in all absolutely identifying about 50 species in addition to those taken at Chapel Hill.

I am greatly indebted to H. H. & C. S. Brimley,* taxider- mists of Raleigh, for records of species collected and observed by them during a period extending over the last four or five 3'ears, in the vicinity of Raleigh, Currituck Sound, New Bern and Beaufort. One hundred and seventy-five species were noted in the vicinity of Raleigh, many of these being duplicated and some additions made from the coast region.

I have also had for reference "A List of Birds of Buncombe County, N. C.,'' by John S. Cairns,t Weaversville, N. C. This list enumerates 169 species observed in Buncombe county.

Mr. Charles F. Batchelder, of Cambridge, Mass., kindly sent me a copy of a pamphlet^ describing his observations upon the winter birds of the mountain region in 1886. In this he enu- merates 40 species.

* Any parties desiring good skins for mounting:, or wishing any work from a taxidermist, will do well to write to Mr. Briraley. I have seen specimens of his workmanship. The work is in every way satisfactory.

Mr. William Brewster, of Cambridge, Mass., curator of birds aud mammals in the Museum of Comparativ^e Zoology, loaned me a copy of a pamphlet* describing a two weeks tour in the mountain region, from which I have gleaned the most important informa- tion concerning the occurrence of the summer visitors of that region. This pamphlet enumerates 102 species.

The private collection of James Busbee, of Raleigh, contains 87 North Carolina species, most of which were collected in the vicinity of Raleigh. This list furnishes some very rare occur- rences.

I take this opportunity of recognizing the aid given, in deter- mining the nesting of our birds, by Drs. Kemp P. and Herbert B. Battle, of Raleigh, from a collection of eggs made by them. The 3ggs were recently determined by the curator of oology at the Smithsonian institution. The list contains 57 North Caro- lina species.

Where credit is due any of the above named gentlemen for observations on any but our very common birds, I have given it under each species.

Rich variety of bird life. A glance at the map of the East- ern United States will show that North Carolina is peculiarly situated, not only with reference to its central position from north to south, and its great extent east and west, but also in the variety of its physical features. It is situated between the par- allels of latitude 33|° and 36|° north, and longitude 75J° and 84 J° west from Greenwich ; approximately 580 miles long from Cape Hatteras to the western limits of Cherokee county, and 200 miles wide in the vicinity of Ca})e Fear, with 300 miles of sea-coast in the east and 200 miles of mountain rano;e in the west. The coast region, with Currituck, Albemarle, and Pam- lico, and the lesser sounds, with the attendant estuaries, numer- ous rivers, and extensive salt and fresh water marshes, invites vast numbers of Diving Birds, Long-winged-, Toti])almate-, and Lamellirostral-Swimmers, Shore Birds, Herons, Ibises, Rails,

etc., and becomes, from its extent in central position, the recip- ient of many extra-limital species from the fauna to the north and south. Perha[)s no phice east of the Rockies is more inter- esting in proportion to its area than is the mountain region of Western Nortli Carolina. It possesses the liighest peak east of the Rocky Mountains. Starting in the valleys at the foot of some of the highest peaks, in the ascent of th(i mountain side we can pass through successively four different faunae, the Lou- isianian, Carolinian, Alleghanian, and Canadian,* having rep- resented as it were upon one mountain side characteristic species from an extent of territory reach i no: from the Gulf States to British America. In the middle region nature has also pro- vided for the retention of numbers and variety of the feathered kind, notwithstanding the encroachment of human civilization upon their primeval haunts. The "rolling" character of the surface with its attendant tree- and bush-begirt streams and val- leys; the worn-out hillsides grown up to "old field pine"; and the steep rocky places incapable of cultivation, offer a peaceful harbor to such as are not yet emboldened to live near the habi- tation of man.

The varied climate in different sections also testifies to the natural adaptation of the State to the reception of widely differ- ent fauna?, or the same fauna at different parts of the State at different seasons of the year. The following table will illustrate the average temperature of the different regions for the four sea- sons of the year. The figures are taken from a table made by the North Carolina Geological Survey, covering observations made during eight to fifteen years in various parts of the State. I select only those figures which represent the temperature of the regions I have chosen for use in the present pamphlet.

These represent the average taken from a number of places in each region. In the mountain region it gives no adequate idea of the temperature upon the upper slopes of the highest mountains, where we have represented the Canadian fauna. A table for Smithville, in the extreme south-eastern part of the State, will illustrate how much warmer is such a southern point on the coast.

In the mountain region, for example, we find on the higher mountains as summer sojourners Wilson's Thrushes, Yellow- throated Vireos, Rose-bi'easted Grosbeaks, Winter Wrens, Gol- den-crested Kinglets, etc., which in the middle region are only winter visitors, or only transients going to Middle America, Northern South America, or the West Indies for the winter; while some, the Towhee Bunting {Pipilo erythrophthalmus), for example, are summer sojourners in the mountain region, tran- sients in the middle, and winter visitors in the coast region, and the extent of the State from north to south scarcely exceeds 2^ degrees latitude! We cannot, of course, say that the same indi- viduals spend the entire year in the State, but it would not be singular if quite a number of the summer visitors to the mount- ain region pass eastward with the approach of winter and reside for the time in the coast region.

While at Beaufort in the latter part of December, 1887, Cat- birds (Galeoscoptes cavolinensis), Brown Thrashers {Harporhyn- chus rufus), Towhee Buntings (Pipilo erythrophthalmus), were in abundance, and evidently settled down for the winter. I was told that they were common during the winter.

Take such a point as Smithville, and we might expect to find ((uite a number of winter visitors that are only known as ti'an- sients in the middle, and summer sojourners in the mountain region.

50 JOURNAL OF THE

Rare species , and non- occur rence of species once abundant. As rare species we may reasonably expect to take, at least in the south-east part of the State, nearly all the species commonly accredited to South Carolina. The taking of Helinaia swain- sonii by Brimley is an evidence of this. The nesting of Peuccea cestivalis hackmani at Cliapel Hill also shows how well adapted North Carolina is for species accredited usually to the States farther south. A glance at the map will show that Smithville is only one degree of latitude north of Charleston, while it is more than one degree south of the northern border of South Carolina.

The disappearance of the Ivory-billed Woodpecker and the Carolina Paroquet from North Carolina and the other States constituting the northern portions of their habitat, and their restriction to the Gulf States, furnish examples of the change of distribution of some species, as affected by changes in their environment. It would not be surprising if at some time in the not far future they should become extinct species. They are placed in the present catalogue because of their former abund- ance in the State, and the possibility that their restriction to more southern districts may prevent their ever being taken in the State again. They should be looked for in the south-eastern part of the State.

Preserve a rich avian fauna. The value of birds as scaven- gers, in destroying injurious insects, and their value in affording objects for the cultivation of our perception of the beautiful, is well recognized. Birds are subject to the same laws in the struggle for existence that other animals are, and man should take care that unnecessary encroachments u[)on their existence be avoided. The reckless and indiscriminate collection and rob- bing: of birds' nests, which annually cuts off thousands of the possible increase of beautiful and useful birds, should be stopped. The merciless and wholesale slaughter, which some- times takes place during the migration of birds to their summer abodes, should cease. Laws to this effect would be of little avail without the support of an interested pul)lic sentiment. Let a

ELISHA MITCHELL SCIENTIFIC SOCIETY. 51

few men in various parts of the State devote their spare time to the study of the birds of their section, recording the result of their observation ; let a general knowledge of the habits and use- fultiess of birds become a part of the instruction in the common schools, and ere long the birds will be in such popular favor that thev will be encourag-ed to come and stav, instead of beino; gradually driven to remote regions and to possible extinction.

Explanation of terms in the catalogue. In arranging the cata- logue I have followed the "Canons of Nomenclature" adopted bv the American Ornit hoi ovists Union.

The catalogue enumerates 255 species and subspecies.

An Appendix is added, consisting of 81 species and sub- species, which we may reasonably expect to take, with careful work, within the limits of the State. This would make in all 336 species and subspecies, and there is a hopeful possibility of the number being still farther increased by the appearance of casual and accidental visitors.

The numbers in parenthesis correspond with those of the A. O. U. Check List of North American Birds.

The vernacular name adopted by the A. O. U. is placed immediately following the scientific name, and in some cases synonymic vernacular names are added in quotation.

(Coll. of 1877) refers to specimens which were collected at Chapel Hill, during the spring of 1877, by several students at the University.

(Univ. Coll.) refers to the specimen deposited in the Univer- sity museum. Any one wishing to donate specimens to the University may be assured that they will be well cared for, and properly labelled.

The numbers marked * are species known to breed in the State. Many others breed, but we have as yet no positive evi- dence of the fact.

On the principle that the avian fauna of the higher portions of the mountain region is similar to that

70 JOURNAL OF THE

of the Canadian avian fauna, as Brewster has shown, the form from this region would be that of the Northern Raven. In the absence of positive testimony on this point I place this sub- species in the list provisionally.

142. ( — ). C. corax prlncvpalis Ridgw. Northern Raven. One specimen taken by Clark and Morgan, of New Bern, and now in their possession, I have determined as belonging to this subspecies. I saw the specimen and took the following meas- urements: Length 26.50, wing 16.75, tail 10.25, tarsus 2.85, culmen 3.19, depth of bill at nostril 1.12. The Raven is reported from the coast region by Brimley, but no measurements given. It may be quite possible that both subspecies, and inter- grade forms, w^ould occur, situated, as the State is, somewhat between the Canadian and Mexican faunae.

SINGULAR ADAPTATION IN NEST-MAKING BY AN ANT, CREMASTOGASTER LINEOLATA"' SAY.

[See plate at back of Journal.]

GEORGE F. ATKINSON.

A month ago I received an ant's nest, sent by Assistant En- gineer Henry A. Brown to General W. Lewis, of Goldsboro, N. C. The nest was built several feet from the ground on a bush, in the marshes bordering Broad creek, Hyde county, N. C.

This ant usually nests " under stones or underneath and within the decayed matter of old logs and stumps. This material is sometimes prepared by the ant as a paper-like pulp, and arranged into cells and chambers, which are attached to the surface of the logs.'^t

This nest is about eighteen inches long by twelve inches in circumference at greatest diameter. I made a longitudinal sec- tion of it, and had a photograph taken, so as to represent both the external form and internal structure. The ants were alive in the nest when I received it. They were chloroformed before sectioning the nest. I took from the nest about one-fourth pint of adults, pupse, and larvae. They were collected in a mass through the chambers within a space four inches in length of the nest. This space is about two-thirds the distance from the lower end. The material composing the cells in this space is lighter in color than the other internal parts. It appeared also in the photograph, as can be seen by looking at the right-hand figure. Probably it will be visible in the photoengravure.

The material used in making the nest seems to be the same used by the ant in making its nest under stones, etc. Beside the woody pulp, a microscopic examination seems to reveal also

*The ant was determined for me through the kindness of Prof. C. V. Riley. tComstock's Report on Cotton Insects, 1879, p. 188.

ELISHA MITCHELL SCIENTIFIC SOCIETY. 89

some portions of dried grass. The nest is supporte<l by the branches of the bush ; a vine and some stalks of marsh-grass are fastened in it. Upon the outside the material is of a light gray oolor, much like that of" the nest of the white-faced hornet. Tn the interior it is darker, in some places almost black. Probably the high tides causing the creek to overflow forced the ants to build their nest above the high- water mark instead of under stones and within logs. One cannot help thinking that possi- bly some species of Hymenopteia, which now altogether build elevated nests, once built them near the ground, and being forced for a long time by conditions surrounding them, similar to these, finally acquired that habit permanently.

This would seem more plausible if General Lewis is correct in a fact which he states, that the yellow-jackets along Holly creek, in Pender countv, build nests on the bushes to avoid the tide. I mean to investigate this and see if they are the same species which under ordinary circumstances build nests in the ground.

A EEMARKABLE CASE OF PHOSPHORESCE.NX^E IX

AN EARTH-WORM.

[See plate at back of Journal.]

GEORGE F. ATKINSON.

On the night of June 20, 1887, when returning from placing some Phengodes females where they might attract the males, I saw in the path before me a small phos})horescent light. As I apj)roached it became larger; now an inch, and the next moment two inches long. I was on the })oint of declaring I had found another Phengodes when suddenly it became three, four, and six- inches long, now darting in this direction and then in that. ]2

90 ' JOURNAL OF THE

Thinking there might be an insect capable of running and giving a phosphorescent light to objects in its path in sncli a way as to cause them to be illuminated for a short time, I struck a match so that I might see to capture it. As the light of the match overcame the j)hosphorescence and lighted up the objects on the ground, the only insect I saw was a Myriapod scampering away under the leaves. All this took place in less time than it takes to tell it. Thinking the insect was hidden under the leaves, when the light of the match was extinguished I began to brush them away with my hand. The phosphorescence appeared again, and the light advanced as rapidly as I moved my hand. I thought certainly I was in pursuit of the prize, and in my anxiety to capture it I would catch up a whole handful of earth. But I always noticed that I left the ])hosphorescent light on the ground. The insect eluded me, I thought. After pursuing the phantom in vain for some time, I stopped to ponder. After the habit of a puzzled man in an inquiring mood, I brushed my foot across the earth before me, when lo ! each little pebble and pellet of earth bristled with a phosphorescent light. For a moment I seemed to lose confidence in the fact that all such phenomena are due to natural causes. The air was sparkling with fire-flies, and the earth at my feet was bristling with phos- phorescence. Had time sped backward twenty centuries, and were the vestal fires lighting around me ? Or was some great calamity impending? I seemed to hear these words repeated from the sky: " Nate dea, quo fata trahunt retrahuntque^ sequamur ; Quid- quid erit superanda omnis forturia ferendo est^ But in a mo- ment more I had brushed away these delightful superstitions, and went to work to find the cause.

Taking a quantity of the earth, I went to my study. First I took several pebbles into a dark i-oom and rubbed them in my hands; no light appeared. Then I took some i)ellets of earth and treated them in like manner; result the same. Surely, I thought, the ])hantom lies in these decaying leaves, but disap- pointment was also the result of the third investigation. I returned to my package of earth, and saw a lone earth-worm

ELISIIA MITCHELI^ SCIENTIFIC SUCIETY. 91

writhing in pain. "I will trv him," I thought. I took it into the dark room. It showed no sign of phosphorescence, I rolled it once across mv hand. The 2)Ji(nitom became real. Not oidy was the whole body of the earth-worm luminous, but the entire palm of my hand was aglow with phosphorescence. I niade several trips to the place and secured other worms which exhibited the same peculiarity.

Probably the Myi'iapod which I saw had pounced upon one of these worms for a meal. It became phosphorescent, which may have frightene<l the Myria})()d, and it ran, dragging its prey, and the worm's body touching the ground illuminated it, thus attra(;tino: mv attention. When the earth is disturbed, the fric- tion of the body against tlic particles gives phosphoresence to them. The earth-worm is probal)Iy a species of I^umbricedse.

Professor Forbes, of Champaign, 111., has kindly sent me an extract from '^System und MorpJiologie der OUcjochaeten ; von Dr. Franz Vejdovsky, p. 67, 1884,""^ from which I make the following abbreviated translation:

It appears probable that this remarkable phenomenon lies in a substance secreted by glands of the skin. The phosphorescence of earth-worms has been repeatedly observed. The first publica- tion thereupon was by Grimm in 1670; and later by Flaugergues in Liclitenberg's Magazine (1781 ).t In the present century Cohn published some observations. J; A. Delia Valle, Panceri, Siechi and Phipson have each undertaken researches upon this subject. Panceri§ declares that the phosphorescence of earth-worms lies in single glands u])on the surface of the body, and that the eleva- tion of the temperature pioduces the phosphorescent light. Siecthiy found by spectroscopic analysis that the phosphorescent light is not monochromatic, but is made up of red and violet rays. Phipson^ traced the production of the light in animals to a homogeneous substance (uoctilucln) which seems to possess the power of oxidation when in contact with damp aii'.

OBSERVATIONS ON THP] FEMALE FOKM OF FHENGODES LATICOLLIS HORN.

[See plate at back of Journal].

GEORGE F. ATKINSON.

Entomologists will remember the interest taken, about one year ago, in the discovery that the female form of a Lampyrid* (Zarhijns rwersi) was larva-like, and liiat the three stages — larva, pupa, and adult — differed but little. On the night of September 27, 1886, a larviform, luminous beetle was collected on one of the walks of the campus of the University of North Carolina.

Pupa State. — As the insect cast its skin only once — in the spring of 1887 — after coming into my possession, this must rep- resent its pupa state.

Description. — Length when crawling, two and three-fourths inches; width, three-eighths inch. Flattened, larviform, lumi- nous ; composed of twelve segments (exclusive of the head), taper- ins: gentlv behind, and more decidedly on the three anterior seg- ments. Chitinous plates on dorsum blackish-brown, the second to eleventh inclusive with a pair of large, light-brown, oval spots. Anal plate light-brown, except a median band of blackish-brown, convex behind. First plate light-brown, except a median irregu- lar and two lateral blackish-brown spots. Below each stigmata, on the fourth to eleventh segments inclusive, are two longitudinal folds, the anterior half of each fold blackish-brown, shading into light-brown in the middle, and becoming yellowish-white, with an olive tinge on the posterior half. Posterior edge of each dor- sal plate dark olive-brown; the posterior angles of the pro-, meso-, and meta-thoracic plate and the anterior third of the pro- thoracic plate yellowish-white, tinged with olive. On the fifth

to ninth segments inclusive (ventral surface) are one pair each of small, elongated, black clots, corresponding very nearly in posi- tion with the pairs of luminous organs of the ventral surface. Anal proleg blackish-brown above, yellowish-white below.

Besides the stigmata on the fourth to eleventh segments, there is one on the ventral surface of each anterior corner of the meso- thoracic segment; also two pairs of small dorsal spiracles, one each between the fourth and fifth, and fifth and sixth segments.

Thoracic legs brown, suffused with yellowish-olive. Tarsus two-jointed; single claw curved. Anterior edge of femur with a row of short hairs; under edge of tibia and first joint of tar- sus with a similar row of hairs; under edge of last joint of tar- sus with small, short papillae. Head black, 2| mm. in width, retractile. Mandibles curved, sickle-shaped, black. Antennae four-jointed: labial palpi two-jointed (or three-jointed? Those of a larva collected in July appear three-jointed): maxillarv palpi four-jointed.

The location and form of the phosphorescent lights are as follows: On each side is a row of circular ones, one on each seir- ment from the second to the twelfth inclusive. Each of these is nearly one-eighth inch in diameter, and situated in the posterior end of the upper longitudinal fold. The posterior edge of each segment, from the second to the twelfth inclusive, emits a band of light. On the under surface are five pairs mere points, one I)air each on the fifth to ninth segments. The general appear- ance is that of a worm beautifully illuminated with bluish-white lights, which are disposed in a longitudinal row on each side, and in transverse bands.

The insect was placed in a small, elongated vial, so that I might ea.sily observe and exhibit the display of lights. The light was brilliant until 11 p. m. on the night of September 27. At 2 A. M. on the 28th the phosphorescence had disappeared. It did not appear again until the night of the 30th, when, by disturb- ing the insect, the lights began to glow, but continued only for a few hours. For a few nights, within the space of a week, I observed that the insect glowed only when disturbed. After that

94 JOURNAL OF THE

the phosphorescence re-nppeared, and I do not believe once disap- peared again until it was placed in alcohol, June 16, 1887.

October 1, 1886, I placed it in a glass jar of earth. It made a cell in the earth next the side of the jar, Avhere I could observe the phos])horescence, and where it remained (excepting one warm day in February, 1887, when it came to the surface, and returned at night when I placed the jar in a cooler ])lace in my room) coiled up until the 15th of A])ril. At that time the luminosity was becoming more brilliant and the brown color was disappear- ing, to be replaced by a uniform cream coloi\

I removed the earth from above the cell and took tlic insect in my hand. It immediately straightened and began crawling. When placed in the jar it sought its cell and there remained. Instead of returning the earth I placed a glass over it, so that I might observe the beautiiul display of light. It was so strong that I could read print by it when the letters were one-eighth inch lono;. About the 1st of May it ca^t its skin and became of a uniform cream color, lighter on the sides and ventral surface and between the segments of the dorsum.

Every night it came from its cell and wandered about the jar, probably striving to attract its mate. May 8 I took it out of doors at night, and placed it on the ground for about fifteen minutes. Nothing was attracted. Twice I took it in the day- time,— the 10th and r2th of May, — but nothing was attracted.

May 19 I placed it, with another (collected by Professor Holmes), in a large, open, glass jar, with about one inch in depth of earth. This I partly sunk in the earth in the open woods just at dusk. At nine o'clock the same evening I visited the place and saw a male within the jar. When it left its mate I caught it.* On the f >llowing morning I found another male outside the jar. The Ibllowing night I captured two more males. Dur- ing the day the females remained beneath the surface of the earth.

The luminosity in this case is decidedly of sexual significance, attracting the males at night. Mr. Rivers concluded that the

^Determined by Professor Riley as Pheiigodes laticollis Horn.

ELISHA MITCHELL SCIENTIFIC SOCIETY. 9o

lunniiosity of the female Zarhipis riversi was not of sexual sig- nificance, as males were attracted by day. He was at a loss to account for its utility.

Soon after meeting with the males the females became less active, and the luminosity, though plainly visible, was less in brilliancy. About June 4 they made each a cell in the earth and began depositing eggs. One deposited about twenty, and the other about thirty-five. The eggs are dull whitish in color, 3 mm. to 4 mm. in diameter. This, I believe, is the first instance on record yf the eggs of any of the Phengodini. The female is coiled up in the cell while depositing the eggs, and afterwards lies coiled up on them. They are then very weak, and soon die. Can it be that the parent yields its dying or dead body as the first meal for its young? One which was found in September, 1886, was taken from the eggs when nearly dead and placed in alcohol. The eggs of this one proved infertile. The mouth parts, and especially the legs, were very much atrophied, and description was well-nigh impossible. In general appearance the adult is very much like that of the larva and pupa. The two which I observed did not, however, resume the dark-brown color, but remained of an uniform pale-cream color, lighter on sides, under parts, and between the segments of the dorsum.

Occasionally during the adult state the one which I kept through the winter showed signs of luminosity on the pro-tho- racic segment. Tlie other one exhibited no sign of luminosity on the pro- and meso-thoracic segments. Professor Riley, some years ago, figured a similar phosphorescent insect, and in the paper, read before the Washington Entomological Society, he says that one found by him in 1869 was figured in Le Baron's fourth Illinois report.

The males are insignificant when compared to the females in size and beaut v. Thev are 15 mm. to 20 mm. in lenpth. AntenuiTe plumose, and half, or more than half, as long as the body. The elytra are short, thin, and subulate.

ANALYSES OF NORTH CAROLINA WINES.

F. P. VENABLE AND W. K. PHILLIPS.

So far as we are aware no analyses of the wines profluced in tliis State have ever been published. As the industry has grown greatly in the past few years and gives promise of still greater growth, it is manifestly of importance that these wines should be analyzed. A comparison is thus possible with the wines of other localities and our knowledm) of the chemistry of wines increased. The wines were, in all, save one case, furnished us direct by the makers. Where we have learned of additions made to the fermented juice of the grape, note has been made of it in the table.

Of special interest are the analyses of wines made from the native Scuppernong vine and t'le closely related grapes — the Mish, or Meisch, and Bulay. The Scuppernong is very abundant, hardy and prolific in certain sections of the State, and the problem, of fermenting and blending, so as to secure a good wine from it is very important.

In the accompanying table will be found analyses of nineteen varieties of wine. The analyses were carried out according to the methods recommended by the German Commission of 1884 as recorded by Earth. The figures in the last nine columns represent percentages. The percentage of alcohol is given both by weight and by volume. The "extract" is that which is called generally the "body" of the wine and includes all of that portion which will not evaporate at 100°.

With regard to the volatile or acetic acid, the total acid was first determined then tliat whicli was left after evaporation on the water-bath. The method was carefully tested and found to be correct. The tannin was determined by comparison of the

ELISHA MITCHELL SCIENTIFIC SOCIETY. 97

depth of precipitate produced by ferric chloride after the addition of sodium acetate, with that produced in solutions of known strength. The extract was determined by evaporation on a water- batli followed by two and a half hours heating in the steam bath. As the temperature of the steam-bath generally lies between 95° and 97° the results thus obtained are high com- pared with those gotten by heating at 100° or 110°.

ACTION OF CHLOROUS ACID UPON HEPTYLEN

ROBERT G. GRTSSOM.

The lieptane from Pinus Sabiniana has been shown by Schor- lemnier to be propably a normal heptane. The heptylen nsed in the following experiments was prepared from this heptane by first brominating it and then acting upon the secondary bromide formed with sodium eihylate. It was found that the best results were secured by allowing the sodium ethylate to act from twelve to twenty-four hours in the cold and then distilling off the hep- tylen and alcoiiol together. The end of the condenser tube may dip underneatli water or, better end just above the surface of it, thus separating the alcohol from the heptylen. The latter does not seem to be soluble in water to any extent. This heptylen was dried, re-distilled and the portion boiling at 98 — 100° was used for the experiments.

The chlorous acid was formed by the action of sulphuric acid, diluted with two parts of water, on a mixture of potassium chlo- rate with half its weight of oxalic acid. The stream of chlorous acid gas mixed with carbon dioxide, thus produced, was then led into the tube containing the heptylen. To start the evolution of the gases the small flask containing the potassium chlorate and oxalic acid mixed with sulphuric acid was gently warmed by placing it in warm water. Application of cold svater was used to moderate the action when necessary. Only ten or fifteen grammes of potassium chlorate were used at one time.

Following the directions of Domac (Annalen d. Chemie 213, p. 12o), the heptylen (about 110 grammes) was placed in four tall test-tubes so that each was a little over half full. These were properly connected with the flask for generating the gases and were surrounded by ice-water. The gas delivery tube ended just above the surface of the heptylen, thus adopting Domac's pre-

100 JOURNAL OF THE

caution, so as to avoid the troublesome explosions. To make the absorption as regular as possible the position of the tubes with reference to the generating flask was regularly changed. The absorption was rapid, the heptylen going through various changes of color from yellow to deep orange-brown. When the deeper color was reached, the tubes were disconnected from the generating flask and placed in direct sunlight until the orange- color was lost. If taken from the ice-water the heptylen became very warm and a rapid evolution of gas took place. It was much the best, and tended to prevent a complication of reactions, to keep the tubes all the time at a low temperature and to shade them well from sunlight during the passage of the gas. After some days the absorption took place more slowly and an exposure of many hours was needed for decolorization. Even with great care explosions would take place after the heptylen was largely saturated with the gas, and about half of the heptylen was thus lost. It was necessary then to stop before complete saturation or a permanent coloration w^as reached. The oily liquid was thor- oughly washed with water until the washings no longer had an acid reaction. This wash-water acquired a pungent irritating odor. The remaining oil w^as dried over calcium chloride.

Aqueous Solution. — On examining first the water used in washing, it was found strongly acid, still but little of the original liquid seemed to have gone into solution. A portion of the water was placed over sulphuric acid and on evaporation left a small residue, white, deliquescent and somewhat oily. The main part was apparently crystallized, contained chlorine and had the smell of acetic acid and its chlorine derivatives. The amount obtained was too small for purification or further attempts at identification. The remainder of the solution was neutralized with barium carbonate, changing from a clear liquid to a rosy flesh- color, with the same fruity, pungent, irritating odor. This was filtered and, after evaporating to a small bulk, the barium precipi- tated by sulphuric acid. After filtering again, it was distilled. Three fractions were taken. The first under 100° gave no test for chlorine. The second, 100 — 101 ° contained chlorine. The

ELISHA MITCHELL SCIENTIFIC SOCIETY 101

third^ 101 — 110° contained both chlorine and .sulphuric acid, the latter coming from the slight excess used in precipitating the barium. As the first only gav^e promise of interesting results, it was saturated with Agfi, filtered, evaporated over sulphuric acid and the thin crystalline film left was analyzed. xVs the amount of silver found was within two per cent, of that required for silver acetate it was concluded that the principal acid present in the aqueous solution was acetic acid. The presence of the chlorine, sulphuric acid and oily impurities prevented an exami- nation of the other fractions for butyric or other acids and the amount was too small to attempt to purify them.

The Oil Insoluble in Water. — The oily portion after the washing and thorough drying over calcium chloride was sub- jected to fractional distillation under diminished pressure."^' In this fractionation that part boiling below 120° was looked upon as mainly unchanged heptylen. The fraction from 120° — 160° was set aside. It contained chlorine and in after attempts at reduction persistently retained it. The remaining portion was fractionated three times, yielding fractions as follows : A. 160° — 173°; B. 173°— 177°; C. 177°— 185°; D. 185°— 200°; and E. over 200°. This last fraction was quite small, the thermom- eter rising rapidly until only a few drops remained. None of these fractions were more than a few c. c. in amount. All were at first clear, colorless liquids, but the last two rapidly darkened even thouo^h in sealed tubes and carefully secluded from the liiiht.

Fraction B was the largest in amount (6 — 7 c. c), and as the thermometer rose slowly from 173° — 177° this was supposed to be the purest substance or the nearest approach to a single chemi- cal individual. As stated before, it was the result of three care- fid fractionations. It was subjected to the first and most com-

*It was found in this case and others where a not very stable product had to be distilled that a reduction of pressure by 100 mm. was sufficient to admit of the distillation eoing on without decomposition. Apparently all that was necessary was a rapid removal and condensation of the vapors formed so as not to subject them for any great length of time to the action of the heat or of products of decomposition already formed. The reduction of pressure reached could ouly lower the boiling point a few degrees.

The following analyses were made of these respective fractions :

It will be observed that while the percentage of hydrogen is about the same throughout the percentage of carbon increases

ELISHA MITCHELL SCIENTIFIC SOCIETY. 103

Up to the last fraction E. This one approaches in all of its percentages very nearly to C^ H,3 Clo. That it is free from impu- rity is hardly possible because of inconstant boiling point. As to the nature of the more highly chlorinated body or bodies with which it is mixed, nothing can be determined by the analyses. From the great difficulty with which the chlorine was removed, it is most probable that simple chlorides were present. Nitric acid caused complete decomposition only in the neighborhood of 200° and nascent hydrogen failed to act.

As the nature of the reduction products would throw some light on the composition of these fractions, their reduction was attempted. First iron filings and acetic acid were used, then sodium amalgam, but the chlorine was not entirely removed even after days of action. The small amounts experimented with rendered vain any attempt at separation by distilling. To sum up the results of the action of hypochlorous acid upon heptylen from Pinus Sabiniana, we find acetic acid and some chlorinated solid acid fi)rMied by the oxidiziup; action, but the main portion changed into a chlorhydrin mixed probably with chlorides. The ease of decomposition of the hypochlorous acid renders it hardly possible to limit the nature of the reaction and prevent its becoming very complex.

A NEW FORM OF BUNSEN BURNER.

[See figure at back of Journal.]

F. P. VENABLE.

In using gas prepared from gasoline for heating purposes in the laboratory, I have been much troubled bv the smoky flame given by the ordinary burner when fresh gasoline is in the gen- erator. This is due to the larger amount of light hydro-carbons present at that time and to the decreased pressure.

104 JOURNAL OF THE

For the complete combii.stion of the gas, then, it is necessary to increase the proportion of oxygen admitted to secnre a good flamCj the pressure must be greater and a fine draught insured. Since devising this modification of the Bunsen burner, I have had no difficulty in the use of the carburetted air. The Spring- field gas machine in use is a small one, holding about three bar- rels, and we pay careful attention to the specific gravity of the gasoline used and to the weight of the stone which runs the fan, thus securing the best results. The burner presents so many advantages in its use, however, that I have thought it advisable to draw attention to it as a good form also for laboratories where coal-gas is at command. The main feature is that the supply of gas is regulated at the base of the burner by a milled wheel and that this supply is diminished only at the issuing jet inside the chimney.

The advantages are: 1st. An easy and convenient mode of regulating the supply of gas, independent of the regulation of the air.

2d. The screw motion gives a means of securing a gradual and accurate decrease or increase of flame.

3d. As the gas is checked in its flow only at the issuiag jet there is but little diminution of pressure, which for the use of gasoline gas is a very essential point. It enables one to secure a very small and still colorless flame.

4th. This burner is a very powerful one.

This burner has proved very satisfactory in the laboratory here, and very favorable reports of it have been received from laboratories using coal-gas where it has been tried. The burner is manufactured by Gilbert & Barker Manufacturing Company of New York.

NOTE ON A NEW TEST FOR IRON.

A solution of cobalt nitrate to which strong hydrochloric acid has been added, is blue. It was noticed that when some impure hydrochloric acid was used a green color was gotten instead of the blue. This change was traced to the iron in the acid, and as I have seen no mention of it elsewhere, I venture to give the present notice of this test. It is very simple, rapid and delicate for detecting traces of iron and is especially useful in testing strong acids. The delicacy of the test is such that when even TFoVo 0" ^^ ^ gramme of a ferric salt are added to the blue strongly acid solution mentioned abov^e, the green is clearly given. With a somewhat larger amount this green is quite vivid. If too much of the ferric solution is used the cobalt solution becomes pink from the addition of water. The test is not given by fer- rous salts, nor does the presence of ferrous salts interfere with it. I have thought that the green was due to the addition of yellow ferric chloride to blue cobalt solution. Other yellow solutions which I have tested failed, however, to give the green.

ELECTROLYSIS OF WATER.

[See figure at back of Journal.]

F. P. VENABLE.

A short note recently appeared in the Journal of Analytical Chemi.stry (No. 3, 1887, p. 287), describing a simplification of the ordinary condenser. Adopting, in part, the same idea, I have devised the following simplification of ITofmann's apparatus for the electrolysis of water. This will prove useful where the high

price of the ordinary apparatus is a serious objection to its use, or where one is at a distance from the supply stores and hence forced to make use of some substitute for the store- bought article. The figure at the end of this Journal will show the form of the ap|)aratus. B B are two tubes (about 8 x J inch) which can easily be gotten in the form in the diagram by taking a single tube of double the length mentioned, giving it the desired bend and then scratching and breaking in the middle. A stout piece of rubber tubing unites these at A. This tubing is by means of a cork-borer perforated in the centre between the tubes B. Into this opening a tube C is inserted, bent at right-angles at P and with its end enlarged to prevent leaking. It is not necessary to bend at right-angles for some kinds of supports, but the opening in the rubber A may be directly on top and the tube C let right into it. D is a funnel with stop-cock fastened to C by the rub- ber connection A. Into the tubes B wires F F (best of plati- num, with flattened ends, though copper will answer) are placed, reaching nearly to the bend and coming out under the rubber connections O O, passing a short way down the outside, wound round the tube two or three times and ending in loops to which the battery wires may be attached. The tubes B B are connected with jet pieces by means of rubber tubing, and can be tightly closed by pinch-cocks. All rubber connections must be tightly wound with w ire to prevent leakage. The gases produced can be exam- ined at the jets, or a delivery tube attached, running under a test-tube which is placed in a pneumatic trough. As a support the ordinary iron retort-stand may be used, fastening the tubes with wnres. It is better, however, to have a board, blackened or covered with black paper, and nailed to a block so as to stand upright. The tubes B B can be fastened to this by wires going through gimlet-holes. The funnel D can rest in a hole or slit cut in a thin strip tacked across the top of the board.
