 Clifford Richardson on the constitution of 

 Portland cement from a physico-chemical 

 standpoint.

 on experiments with materials which retarH 

 the activity of Portland cement.

 trated account of the Edison Portland ce- 

 ment works, describing the machinery used.

 applied to Portland cement. 



SCIENTIFIC AMERICAN SUPPLEMENT 

 1 561 presents an excellent review by Brysson 

 Cunningham of mortars and cements. 



SCIENTIFIC AMERICAN SUPPLEMENT 

 1533 contains a resume of the cement in- 

 dustry and gives some valuable formulje. 



SCIENTIFIC AMERICAN SUPPLEMENT 

 1575 discusses the manufacture of hydraulic 

 cement. L. L. Stone is the author. 



SCIENTIFIC AMERICAN SUPPLEMENTS 

 1587 and 1588 contain an able paper by 

 Edwin C. Eckel on cement material and 

 industrv of the LTnited States. 



SCIENTIFIC AMERICAN SUPPLEMENT 

 1586 contains a review of concrete mixing 

 machinery by William L. Larkin. 



SCIENTIFIC AMERICAN SUPPLEMENT

 tion of Portland cement for concrete blocks.

 gates. .A helpful paper.

 for mortar and concrete, by Sanford E. 

 Thomson.

The cracks must be filled solid and even with 

 the boards. After the crevices are filled shel- 

 lac or prepared house paint may be applied. 

 When paint is used the floor should be var- 

 nished after the second coat is thoroughly dry. 

 Oak color is more satisfactory in paint than a 

 lighter or a darker shade, as it does not show 

 dust and wears well. To keep a painted floor 

 in good condition it should be dusted every 

 day and oiled occasionally. Crude oil is good 

 for this purpose, and should be applied with a 

 flannel or other lintless cloth. Rubbing after- 

 ward with cheesecloth preserves the polish. 

 Where milk is plentiful it forms an excellent 

 substitute for oil, and is preferable in point of 

 cleanliness. Painted floors that are very dirty 

 may be washed with skim milk or with soap 

 and water. A scrubbing brush should never 

 be used on a painted or varnished floor. 



Varnished and painted floors will keep 

 bright for years if they are wiped clean once 

 a month with a cloth wrung out of warm 

 water, then rubbed with a cloth wet with kero- 

 sene and finally rubbed briskly with a woolen 

 cloth. 



When an oiled floor is soiled it may be 

 cleaned by rubbing with crude petroleum or 

 kerosene. It may also be washed with hot 

 soapsuds. It should always be rubbed per- 

 fectly dry. 



A pretty and artistic way to treat the floors 

 of bedrooms, especially those in summer homes, 

 is to enamel them in the colors used on metal 

 bedsteads. These dull shades harmonize beau- 

 tifully with wall papers, and the matting and 

 denim used for wainscotings. Moss-green 

 shingle stain and the dull copper color used 

 on roofs are very effective with white wood- 

 work, and Dutch blue enamel is just the 

 thing for the floor of a room where the Delft 

 coloring is wanted. No matter what color is 

 chosen, the efiect will be better if the floor 

 matches the tone of the walls. The enameled 

 floor should be varnished and waxed to get 

 the best results. In staining or in painting 

 floors the mistake of hurrying the work is 

 often made. To be well done the work must 

 be very slowly done, allowing plenty of time 

 for every coat of paint to dry thoroughly be- 

 fore another is applied. It is a very desirable 

 thing, if possible, to have the floor untouched 

 for at least twelve hours after the rubbing on 

 of the final application of oil or wax. The 

 floor must be allowed to set and harden if you 

 want it to present a thoroughly satisfactory 

 appearance. 



It is a good plan to have the kitchen floor 

 stained with potash. It is an excellent stain 

 for any floor, but more particularly for that 

 of the kitchen. A quarter of an ounce of per- 

 manganate of potash to each quart of water 

 should be used. It should be applied freely 

 and quickly to a dry floor with a cloth or 

 brush, repeated for a dark color. When it is 

 applied hot it will penetrate the grains of the 

 wood and kill insect germs that may be lurk- 

 ing there. Care should be exercised in 

 handling so that it may not come in contact 

 with the hands, as it is a caustic, therefore 

 one should wear rubber or leather gloves in 

 the operation. A floor thus heated may after- 

 ward be coated with linseed oil, shellac, wax, 

 or varnish. 



For a piazza floor there is no better finish 

 than linseed oil. One thorough oiling should 

 keep the boards in good condition all summer. 

 Oil again in the fall to preserve the boards 

 through the winter. The floor should be 

 swept and washed clean, and when it is dry 

 it should be rubbed with boiled linseed oil. 

 The next day apply a second coat, rubbing in 

 well. The floor will be greatly improved by 

 rubbing with coarse woolen cloths a few days 

 after the oiling. Sweeping and an occasional 

 washing are all that such a floor requires dur- 

 ing the summer.
