i. Beport on the Condition of School Buildings in 24 Wards. INSPECTOR LAYDOH'S OPINION. Two Netr Smallpox Cases Pound in an Unexpected Quarter. CHOLERA HOSPITAL FINISHED TO-DAY A report of tbe sanitary condition of the public, private and parochial schools in the 24 wards of the city, comprising the East End, "West End, Lanrenceyille and South side, has been submitted to Chief Brown by William Linydon, the plumbing inspector, who has just finished a thorongh investigation.

In connection with his report Mr. Laydon makes a number of suggestions of a technical character relative to tbe plumbing and drainage of school buildings. As to the condition of the schools he says his visit had been anticipated in a number of places, the officers in charge having cleaned up cellars, outhouses and back yards to give them the best possible appearance. But even with the preparation he fonnd many of them in bad condition and was astonished to find that those in charge considered the premises perfectly healthy. Tbe inspector calls attention to the fact that many of the schools have neglected to connect their drains with the public sewers, and recommends that, as a measure for pub lic health, such connections be made compulsory.

The report states that in some schools the conveniences are inadequate for a private family, not to mention a collection of a hundred or more children. Damp Cellars Beneath Schools. Attention is called to the condition of the cellars in some of the schools, there appearing a number in the report marked damp, dark, musty and piled with rubbish. A recommendation for lighting, ventilating, and cementing the floors ol the cellars is made. "In several of the Southsjde schools," the report says, "the necessity for filters lias been recognized, and good filters for drinking water are in use.

I would recommend that all schools be compelled to filter water for use of the children, particularly thoe using Monongahela river water, ason the Soutbside, and those using well water, as in a number of schools in the East End. "As a result of my investigation I am of the opinion that inspections of this kind should be made annually, with authority given to the plumbing inspectors to compel school officers to adopt and maintain proper sanitary appliances." In summing up the list of public schools inspected Mr. Laydon calls particular attention to the building in the Twentieth ward known as the Liberty school annex and the Thirty-sixth ward schools as being in a very bad condition, damp, badly ventilated and totally unfit for school purposes. The other public schools are reported as being in a generally fair condition with the exception of one or two of the outlying schools where well water is used and sewers are not used. Some Schools in Excellent Condition.

The Seventeenth, Twenty-first, Twenty-second and the other schools with tbe exception of the Thirty-sixth ward schools are reported in excellent sanitary condition. Of the parochial schools the Ursuline Academy is reported in extra fine condition. Tbe St Peters, St Adelberts school and St Johns parochial schools on the South-side are condemned as being in a Bad sanitary condition, filthy, and in need ot immediate attention. The German Lutheran school in the Fif teenth ward, and the Pennsylvania Female College Twenty-second wa. are also con- ucuium US VCU 1U UdU UUUUIUUU.

-Liiia 13 particularly true of the Female College, where the sanitary arrangements aie inferior and not properly ventilated, allowing foul odors to escape continually. The sewer system in the buildine is also condemned. there being many defective joints, allowing the waste matter to escape on the cellar floors and poisoning tbe atmosphere. DIPHTHEEIi CAUSED AH IHCHEABE. last "Week's Death Bate TFas Much larger Than That of the Previous Week.

The diphtheria outbreak in the Thirteenth and Eighteenth wards caused an increase in the death rate of the city for the last week. The rate was 22.83 for 1,000 inhabitants per annum. In the previous week the rate was only 18.35. Diphtheria caused 13 of tbe 112 deaths and tvphoid fever 10. Thirty-nine deaths were of children under 2 years of age.

Chief Inspector McEwen yesterday said tbe diphtheria was racing in the. J-ast Unci. This Chief Bigelow stoutly denies. "There is less contagious disease in the East End than in nnv section of the city," said the chief. "Inspector McEwen is very much mistaken in including the Eighteenth ward in the East End.

The people in the Thirteenth and Eighteenth wards need Bewers and paved streets. I venture to say there is less disease, for the number of people, in the East End than any other section. The imminent physicians'all tell me they have pss business this year and at this time of year, than they have ever had since locating here. Mr. McEwen's daily reports contradict what he 6avs for publication as I have reason to know." PATTIS0H CHANGES HIS MIHD.

Ho Will Furnish Money to Tight Cholera if It Is Necessary. Secretary Benjamin Lee, of the State Board of Health, had a conference with Governor Pattison in Philadelphia on Thursday. After the meeting Dr. Lee said: "Governor Pattison adv'sed the board to receive no more offer of funds to assist in the establishment of a border inspection and to return what monev had been received. "Will you return the $20,000 which Henry Clay Frick, as chairman of the Carnegie Steel Company, gave to the board?" was asked.

"1 think so," was the answer. Dr. Lee stated that Governpr Pattison promised to give whatever money was needed when tbe emergency arose. The Governor desired a wait of several days to see how the situation would develop. BTEICKKW WITH DISEASE.

Tathcr and Child Badly Affected SmaUpox on Craig Street. With Two cases of smallpox were reported at the office of the Board ol Health yesterday. The cases were Thomas James and his T-weeks-old child. The locality in which tbe iatrily lives is a rather isolated po be ortion of Craig street. The rMM came affected vesterdav immin.

Shortly afterwards the lather began to vomit violently, his bodr began to ache severely and his temperature rose to 'an alarming extent. There is another 2-year-old child living in the house not yet af-iected. Dr. McCandless went out to investigate the case last evening, and ordered the victims removed to the West Penn Hospital. The condition of the habitation in which the disease started is reported as being miserably filthy.

CHOLEBA HOSPITAL BEAST. Xho Sew Structure Will Be Well Adapted to tho Purpose and Itcady To-Day.

SECOND CONGRESS Of the National Beal Estate Association to Be Held October 4 to 7 Inclusive A Notable Gathering. BurrALO, N.

Sept 23, 1S92. Owing to its commanding situation as a railroad center, the city of Buffalo has of late years become very popular as a convention city for meetings of national bodtos. Bat never in her history has she made preparations to receive ft gathering of business men the lmnortance of whose visit will have so wido and beneficial an effect upon her great destiny as will the meeting of tbe National Real Estate Association of America, whose second annnal congress will be held In Buffalo on October 1 to 7 inclusive. Every business or professional man in the United States, who is interested in real estate as an owner, asent or dealer, will be "benefited by the work that will be done in Buffalo by this association, and it is, therefore, receiving very wide attention. Among tbe objects which this association hopes to accomplish Is the establishment or uniform laws throughout the States for the transfer and registry of real property; for better and simpler and more secure legal forms to uo used in the transaction of the real estate uusinos, and for the establishment of a central body of reference and statistics.

The association discourages wild speculation and fictitious "booms," and encourages and aims to direct, as far as possible, the investment of money in sections promising the greatest and safest returns. The association is purely national In its character, and is not controlled by real estate men or any section, and the useiul- ness of such a body cannot be overestimated. The Programme of the CAngress At Buffalo will include an address by the Hon. Chauncey M. Depew, upon Ulapid Transit and Suburban Beal Estate," tRd addresses of eqnal importance and interest will be made by ex-Governor Hubbard, of Texas, and the Hon.

J. Craddoctc Simpson, ol Montreal; Hon. A. S. Colyar, Nashville, Hon.

Seymour Dexter, Elmira, N. Hon. Frederick Bowdltcb, Boston, and Hon. F. C.

Moore. President of the National Board of Fire Underwriters. Delegates to this congress will find the city of Buffalo one ot the most magnificent examples of material prosperity and American civilization. Thev will find a city with SOO.OuO inhabitants, and they will learn that one-half of the inhabitants of Buffalo bavo been added to her population during tbe past 12 years. Thoy will find a municipal government, hose rule has been so intelligent and progressive that it has been able to keep pace lth this unprecedented growth by extending police, lire and water protection; parks, boulevards and pavements; schools and churches, and a seweraore svs- tem lully in keeping with the wants of her 300,000 people, and yet a city whioh leuda 63 American cities in economic taxation.

Of Interest to Visitors. The visitors will find more than 100 miles of smooth asphalt pavement, whioh is nearly twice more miles of this perfect pavement than is possessed by any city in the world. They will find a water snpply, which furnishes an uullmited quantity of pure water from Lake Erie to every inhabitant Buffalo is now the largest coal distributing point in the world; the largest sheep market; the largest fresh fisn market, and with ber suburban rort ot Tonawanda, tho largest lumber maikct in the world. Sbo is the second largest grain, cattle and live stock maiket in tuo world, and tbe valuo of her lake and rail commerce places her as the sixth largest commercial city on the globe. Tbe five cities which surpass her are London, Liverpool, New York, Hamburg and Chicago.

Probably of more general national Interest in this real estate congress will be tbe extension to Buffalo or congratulations by every visitor upon Buffalo's acquisition of Niagara Falls water power by the monstrous tunnel just completed at an expense of many millions of dollars of Wall street capital, which will supply to Buffalo 120,000 horse power, for all manufacturing pmposes electric light. ana lor electric ugnt, at a cost oi one-iourtn ana one-nail the cost pest water power elsewhere in the world. The Hon. Peter A. Porter, who was one of the projectors of this tunnel, will address the congress upon tbe inception, history and completion of the greatest of the world's engineering feats, and the entire congress will adjourn to Niagara Falls to visit the tunnel.

BEAUTIFUL, BEYOND COMPARE. The Pianos at Klebers', COG "Wood Street The musical instruments Just receivedand on exhibition at H. Kleber Bra'a music warerooms, No. SOS Wood street, are objects of delight and admiration. In the presence of these master works of Steinway's, Cono-ver's and Opera pianos, as well as the Vocation church organs, all other makes must take a back seat, and this is the reason why the bulk of the piano and orgau trade is done by tbe Klebor for people know, that no sharp tricks are ever played at Klebers' and that they can buy a piano for upward of $50 lower than at any other music score.

Cholera Is likely to make its appearance at any time. Why not take every precaution to escape it? Buy a "Davis Filter" and you will have done a great deal in the right direction. Its use will insure pure water. PlTTBBUEQ FlLTEB COMPANY. No SO Saudisky street, Allegheny, Pa.
