BOOKS IN WATER-COLOR PAINTING.

SPOKANE FALLS, WASH., December 11, 1889.

TO THE EDITORS OF THE AMERICAN ARCHITECT:

Dear Sirs,—Will you kindly advise, through the columns of your paper, what is the best self-instructing work on architectural water-coloring, and oblige.

INQUIRER.

[The best drill for the eye and hand that we know of can be obtained in the shortest time by getting Buskin's "Elements of Drawing," and doing faithfully and exactly all the exercises which he prescribes, including both those in black-and-white and color. Many people, however, do not care for this drill, but prefer to make a few bad imitations of simple chromos, and consider that equipment enough for architectural work. For those, Penley's large work, the "System of Water-Color Painting" is the best for copying from; or the aspirant may get some of the little Winsor and Newton "Handbooks on Sketching in Water-Colors," to show him how to choose and mix his pigments, and use as models to copy from some of the colored prints of architectural subjects which are to be picked up in the stores. There is a good deal of choice among these. We have ourselves published one or two, from originals by Mr. Botch, which will answer as well as anything we know, being admirable in color and architectural feeling, and just sketchy enough. Pains should generally be taken not to make an elaborate picture of an architectural sketch, and the processes preliminary to making a highly-finished water-color painting, such as laying a ground-color of neutral orange, and sponging it partly out, cutting out foreground lights with a knife, and so on, are best dispensed with. Chinese white, also, should be used very sparingly, and only where the scale is so small that it appears in the form of dots. A good lesson on the importance of keeping color subdued, for the sake of heightening architectural effect, can be derived from any of Front's works, which, by the way, might with great advantage be used to copy from. These will show the value of what most students consider beneath their notice—work in two tints and give the best models possible of artistic distribution of light and shade.—EDS.

THE DUTY ON GLASS AS IT AFFECTS CONSUMERS.—In a letter to the New York Times, Mr. J.S. Moore writes: As I am on the subject of glass, and as the members of the Pan-American Congress are inspecting our magnificent metropolis, I wish to call their attention to two subjects. First, our dirty streets, and second, our splendid windows. Dickens has immortalized the "Golden Dustman." In this city we have the "Dirty Ringman," or we may say "Ringmen." There have been millions in New York's dirty streets. The most honest and persevering Mayors and other high officials have got stuck in New York street mud and were never heard of again. Our aristocratic home mud has flourished without any protection, and the pauper mud of Europe or any other mud could never beat our home product. Here our amiable and friendly Commissioners of the Pan-American Congress can see it demonstrated that our mud industry can flourish without protection. I will now call the attention of our Pan-American friends to the windows in New York houses. They are invariably of plate-glass, and there is not a city in the world that can beat New York in handsome windows. Now, then, it is an actual fact that the tax or duty on plate-glass is as follows: Plate-glass, 10 by 15 inches, 3 cents per foot, or 13.60 per cent; plate-glass, 16 by 24 inches, 5 cents per foot, or 19.78 per cent; plate-glass, 24 by 30 inches, 8 cents per foot, or 27.46 per cent. Now, we must admit that this is a moderate tax. The above glass goes into the houses of the rich. Of course, it will not do to tax influential and rich citizens. But now let me show how we tax that class of people who build three-hundred-dollar houses, or the hundreds of thousands of farmers who live in the far West. Those houses are glazed by what is known as common green window glass. Let me show to what extent we have taxed that class of people in 1888:

We have squeezed out of the neediest, most hard-working of our population $1,563,000 taxes on their "daylight" or window tax, which has gone into the Treasury; but we have squeezed at least $5,000,000 more and put it into the pockets of people who made similar glass. Our Pan-American guests may reflect on the above statistics and come to the conclusion that having flourishing window-glass industries may, after all, not be the highest blessing.

I beg to assure Mr. Carnegie that I am "not" a grumbler, as I don't want to run the risk of having the door of heaven shut in my face when he succeeds St. Peter in office.

THE NATURAL-GAS SUPPLY.—At the recent meeting in New York of the American Geological Society, Prof. Edward Orton, State Geologist of Ohio, and a professor in the State University, in his paper answered those who claim that the great natural gas fields of the country are practically inexhaustible, and that nature is manufacturing the gas by chemical combination in the subterranean cavities as rapidly as it is consumed by man at the surface. He claimed that the supply of natural gas in those States was not only limited, but was being exhausted very rapidly and would be drained in less than nine years. The gas, he said, is now being used as the basis of a varied line of manufactures, the annual products of which aggregate many millions of dollars, and it is driving, besides the iron and steel mills of Pittsburgh, potteries and brick works, over forty glass furnaces and a long list of factories in which cheap power is a desideratum. The gas is the product of ages, which has been accumulated in the porous limestone of Ohio and Indiana. It has been produced so slowly that when once exhausted it will take many thousands of years for it to again accumulate in sufficient quantities to be used, even if the elements necessary for its production were preserved, which he thought was not at all probable. The pressure which forces the gas out with such tremendous power that it sometimes reaches 1,000 pounds pressure per square inch, is not due to the pressure of the gas itself, but to the hydrostatic pressure brought to bear by the column of salt water that enters the porous stratum of rock containing the gas at the sea-level, and which by its weight tends to force the gas out. To the explanation and elucidation of this phenomenon, Professor Orton's paper was more especially devoted. The men who are engaged in the practical development of gas and oil fields, said he, made great account of rock-pressure. It is the first fact they inquire after in a new gas-field. They appreciate its importance, knowing that the distance of the markets they care to reach and the size of the pipes they can employ are entirely dependent upon this element. He defined the term "rock-pressure", and showed the decrease of its rate westward. He said four hundred thousand people in Northwestern Ohio and Central Indiana alone depended upon natural-gas for fuel and illumination.

STATUE GIVING A DOUBLE IMAGE.—At the Italian exhibition in the Champ de Mars there was a statue that attracted much attention from the visitors. It represented Goethe's Marguerite standing before a mirror. This latter gave by reflection the image of Faust. The artifice was well concealed by the sculptor. In reality, it was not a double statue, but the figure of Faust was skilfully obtained by means of the folds of Marguerite's robe.

Marguerite holds her arms in front of her, and these same arms form those of Faust, who holds them crossed behind his back. Faust's face is carved in Marguerite's back hair, and the man's figure is obtained, as before stated, by means of the folds of the woman's robe. This curious object might inspire some of our sculptors with an analogous idea. We do not know the name of the author of the statue, but we can say that it was exhibited by Mr. Francesco Toso, a Venetian manufacturer of mirrors. The statue was of wood, and of nearly life-size.—La Nature.

SITE FOE THE KAISER'S MONUMENT.—Three or four Berlin banks have secured the preemption of all the buildings in Schlossfreiheitstrasse, with a view to pulling them down and fulfilling the Emperor's wish to have his grandfather's monument erected there. Only a few days ago three of the most eminent Berlin architects declared that the place was absolutely unsuited for that purpose. The banks are said to have agreed to pay 5,000,000 marks for the houses, and an equal amount as compensation, and intend to form a lottery of 40,000,000 marks, with prizes to the amount of 30,000,000.—The London Standard.

The salient features of the business situation this week afford every encouragement to the promoters of new schemes and the pioneers in industry. Among the additional factors which will stimulate trade and business during 1890 are the following: The construction of fifty per cent more railway mileage than was built last year; a very great increase in lake tonnage; a large increase in inland water-way tonnage; a very great increase in rolling-stock; a greater increase in locomotive capacity than has been made during any one year in our history; greater activity in house-building, and greater activity in the building of shops and factories. Several other interesting features also deserve mention, among them the very strong probability of the establishment of a larger number of banks daring 1890 than were established during 1889 or any previous year; the more rapid expansion of the building and loan association system, particularly in the newer States; the increase in the output of the gold and silver mines of the West and Southwest; the opening-up of valuable coal-beds in many localities, which will tend to the establishment of little industries; a great increase in the area of land devoted to agriculture. Speaking generally, the agricultural interests will be stimulated. Speaking prophetically, it is very probable that prices will continue to advance, but by infinitesimal degrees. Speaking conservatively and in the light of recent experience, it is safe to assume and assert that production will be evenly gauged to consumptive requirements. Those who have kept a close eye upon the operations of manufacturers in all the leading channels recognize one very gratifying feature, and that is, that they are protecting themselves against unwarranted and unexpected advances in the cost of their raw material by making purchases for future requirements, ranging from three to six months. Users of cotton and wool are largely doing this; so are users of iron ore and iron and steel, as well as users of lumber, stone, cement and building material generally. This general policy of providing for legitimate future requirements is one of those instincts which safely guide the commercial world out of danger into safety. One fruitful source of panics in former periods of activity was the failure of consuming interests to supply themselves with raw material to complete their contracts. The business world has learned wisdom from its experience, and is now quietly turning a corner and wheeling into line safely early in 1890. The tanning interests of the United States have pursued this course in their limited field. The boot and shoe manufacturers, if they have not bought largely of raw material, have, at least, taken such steps as will guarantee them against a sudden advance. The clothing manufacturers have wisely purchased for their future wants; in fact, in almost every avenue of activity this policy has been pursued. The users of Lake ore have already bought five and one-half millions of the seven or eight million tons of ore they will want this year. The users of steel blooms and billets have bought so far ahead that manufacturers are now declining to make further contracts, excepting for very strong reasons. The Southern pig-iron makers are debating with themselves whether they will accept orders for pig-iron to be delivered next summer or wait a few months. Scores of illustrations of this sort could be enumerated. In many quarters this policy is believed to be an unwise one. Experience has shown it to be a safe one.

The iron industry, as a whole, is on a very permanent foundation. Manufacturers are hurrying to complete new works; lumber manufacturers, especially throughout the South, are stimulated to the greatest exertion by two new causes: First, a strong demand throughout the North for the superior lumber-mill products of the South; and second, a wonderful expansion of local demand in the South arising from the new industries there. The makers of nearly all kinds of machinery are busy with new work, fully one-half of which is for delivery in the new Southern or Western States. The manufacturers of steam-pumps, the manufacturers of appliances for new fuel-gas processes, the builders of heavy machinery for steam and electrical purposes, the manufacturers of hoisting-machinery and of machinery for mining purposes, as well as of machinery for general shop-use, have been booking more business since the 1st of October than their present shop-capacity will allow them to execute. Consequently, a general system of enlargement is in progress. Contracts have been lately given out for the construction of machinery to make machines of larger than usual dimensions. Our industries are being reorganized, and instead of engines of five, ten or fifty horse-power, engines of fifty to five hundred horse-power are now common. Agricultural operations are conducted by the aid of machinery upon a larger scale, and within the past six months a score or more of establishments for the manufacture of agricultural implements have been equipped with machinery, and facilities in the Western States, that indicate more clearly than anything else can do the magnitude and scope of our agricultural interests. Last year the rolling stock of the railroads was increased by some 54,000 freight cars, but it is probable that the additional orders this year will reach 100,000. The managers of several of the Western railroad systems have decided to erect repair-shops along their various systems, by which repair work and new work can be more expeditiously and economically done. The springing up of so many little industries along these new lines is creating local markets for farm-products. Last year the opening of coal mines, to the number of about sixty, promises a sufficient supply of coal to these new communities at a low cost. These encouragements are stimulating the outflow of population from the older States, and it is this outflow, coupled with the better conditions for living in the West through the development of industries, that is equalizing in such a healthy and natural way the great manufacturing and agricultural forces. By this growth of little industries, mechanical, mining and railroad, the decline in the value of farm-products is checked, or possibly altogether prevented; or, at least, the demand arising from this cause enables the farmer to obtain the very best possible price for what he has to sell. It is not out of place, at the opening of the year, to briefly direct attention to these forces acting beneath the surface. The manufacturer and merchant have nothing to fear from hidden destructive agencies. During the past two or three years several threatening commercial evils have arisen only to disappear by a self-correcting agency which seems to develop itself at the right time. The merchants and manufacturers of the New England and Middle States will find, this year, a much more valuable market west of the Mississippi than last year. The increasing demand for all kinds of raw material there during the past few months is a sure indication of the growth of a great market for the shop-products.
