The returns show a falling off in the number of producers in all lines save in Gypsum and Lead and Zinc. The greatest reduction in number of producers appears in clay and stone although both show a good growth in total production; Table number I gives the total mineral production by counties and follows herewith: TABLE No. l.

6 MINERAL PRODUCTlON OF low A. Coal. All of the leading coal producing counties show an increased production save Boone, Lucas and Webster counties. Lucas has dropped from the list of large producers. The average price per ton, the average number of days worked and average number of men employed were higher than for the preceding year, in fact higher than during the last decade. The output, total value and Dumber of men employed were the largest in the history of the industry for Iowa. The table below shows the growth in tonnage, value, average price per ton, average number of days. worked and average number of men employed during the past nine years, according to the authority of the United States Geological Survey.

8 MINERAL PRODUCTION OF IOWA. The following table, compiled upon the authority of the United States Geological Survey, shows the production of bituminous coal by the ten leading coal producing states of the Union during 906. It' will be noticed that Iowa maintained her positiop. as ninth in the list according to total tonnage while she holds eighth place in the value of the output. The second table, from the same authority as the first, gives the production of the ten states which produced the largest amounts during 907, and shows that Iowa kept the same relative position, both as to amount and value of output, as she held in the preceding year.

Iowa still maintains her pre-eminence in the manufacture and sale of drain tile. Notwithstanding the installation of numerous factories for the manufacture of cement drain tile there was an.increase of nearly seventeen per cent in the amount of clay drain tile marketed during the year.'

22 MINERAL PRODUCTION OF IOWA. The outlook for 908 is very favorable to increased production, especially in drain tile and sewer pipe. Large plants are in process of building or have recently been built at Lehigh, Fort Dodge, Mason City, Sheffield and Fertile. Pottery. The reduction in pottery production was due to the closing of the plants in Des Moines, Marshall 'and Webster counties. The Fort Dodge Stoneware Company was the largest producer in the state. The product for 907 was as follows: Red Earthen Ware....... $ 8,20 Stoneware................................................ 7,32 Miscellaneous............................................. 3,00 Total.........,........... $8,882 The outlook for 908 is for an increased output due to the rebuilding of the plant at Fort Dodge and the re-opening of the plant at Marshalltown.

The high prices for pig lead and spelter during the early part of 907 gr eatly stimulated mining operations in the Dubuque

MINERAL WATER-GYPSUM. 27 region. Lead ore reached the highest price in several decades, ranging from $42.00 to $20.00 per thousand pounds at the mines. The latter price was reached s!-ortly after the money stringency ill the east. The average price for the year was $38.00 per thousand pounds for lead ore and $30.00 per ton for sphalerite. The amount of ore sold for the year was: Quantity in I Pounds ------;---- Leadore..........................,300,000 $ 49,400 Zinc ore.............................................. 600,000 9,000 A number of companies produced some "dry bone." and "jack" which is still held in stock. The Avenue Top Company completed and put into operation a fifty ton. mill during the year. The outlook for 908 is nqt especially encouraging owing to decreased prices. Mineral Water. The amount of mineral water sold was less than for the preceding year although the price received was greater. The springs at Colfax in Jasper county still contribute the larger portion of the water sold. The amount and value of the water sold during 907 was as follows: Medicinal water.............

28 MINERAL PRODUCTION OF low A.. Sand-lime Brick. The sand-lime brick industry shows no growth in number of plants operating. In fact the plant under construction at Sioux City was not in operation during 907. The output for the year was greater than for 906. The product was distributed as follows: Number in I Thousands I Common brick.............................. 6,29 $ Front brick...........................,... 6 Miscellaneous.................................... 4,47 6,334 3,&3 ------- Total........................................ $,68 Iron. The Missouri Iron Company continued their experimental work during the year and completed the installation of their washer plant. A small amount of ore was shipped. Portland Cement. The Northwestern States Portland Cement Company did not complete their plant at Mason City before the close of the year. 'he plant was put in operation in February, 908, and at the present time is turning out an excellent grade of Portland cement. The Iowa Portland Cement Company of Des Moines and the Hawkeye Portland Cement Company at Harvey in Marion county will scarcely complete their plants in time to become producers during 908. The price of cement to the consumers is considerably less than it was during the preceding year, ranging from fifteen to thirty per cent. Peat. During the year a plant for the briquetting of peat was installed near Fertile in Worth county. The industry was started too late in the season to become a producer during the year 907 and is still in the experimental stage. The plant is expected to have a capacity of twenty tons of dry peat per day.
