l Supi'ui to iHNeSt III new OuiiulilsS p0 account of the high cos; of construc- ton and the consequent small re- turns.
 Output of Fire Brick Increased.
 The large decrease In the output and value of fire brick, which was used in immense quanties in the manufac- ture of munitions during the war. was only natural Another cause for the decrease, however. was the strike in the steel industry, the principal con. sumer of fire brick.
 The average price per unit increased very little in 1919 as compared with 1918. Common brick increased in price IT per cent, face brick 15 per cent, hollow tile eight per cent and vitrified brick or block 30 per cent. The average increase in price of all these wares from 1916 to 1919 was 73 per cent.
 l Structural clay products cs a whole (mainly brick and tile) were valued in 1919 at S102, ,s5O. .OO0 or 50 per cent of the total. compared with S66. 209. 300 In 1918. Engineering products (vitri- | fed brick. sewer pipe and draintile) rose in value from 80. .6T5 GOO in 1918 to S37, 800 900. or 20 per cent of the total. in 1919 Refractor,es (tire brick and stove lining) decreased in value from S52 300 900 in 1918 to $38 900. .000 in 1919. 20 per cent of the total. Mis- | per cent.
 1 Common brick regained it rank ns <, the clay product of greatest value in 1919; but notwithstanding the large gain shown fin the accompanying table. production. in 1919 was the smallest yet recorded by the United States geological survey. except that in 1918. The average price per thousand in 1 1919. S12.19. was the highest recorded by the geological survey.
 Face brick showed the rext larges, increase in actual quantity and value and by far the largest percentage of 1 increase
 Big Gain for Building Tile.
 Hollow building tile or block. which has been steadily gaining in use, in- creased in both output and value m 1 1919. and it's value was the highest recorded. bein. greater by 25 per cent l than in 1917, the year in which it had next greatest value.
 Tile (not drain) also made con siderable increase in value in i019 and reached record value $I.250.0o0. The year of next highest output was l 1917, when the value was SG,S2122l. 1 Architectural terra cotta. which in l 1918 renched it's lowest value since 1900, rallied in 1919; but with the ex- 1 ception of the years of 1908 and 1915. l its value was the lowest since 1904. | With the removal of government re- striction on road building the out put of vltriied brick or block in 1919 | increased somewhat but was apparent ly below the normal. having been lit- l tie more than half the average reached during the preceding len i years. The average price per thou- sand in 1919. $o3.1l. was the highest ever recorded.
 The value of sewer pipe and drain tile also showed large gains in 1919. hnvinc heen exceeded only in l9i1. 1 Sehooi Lunch ts important | According 10 the federal bureau oe education, the school lunch Is rapidly becoming recognized par; of our school system. and should therefore be established through the use of schol funds. with the overhead expenses of conducting the lunch supplied from the same source. The day of the concessionaire Is passing, says the bureau. and il can not pass too quickly. us it turns the | lunch into q commercial enterprise. with the welfare of the children not the first and only consideration. No school lunch should be conducted at a rrotit. Even in the larger schools the receipts from the lunches should at rlle most only cover the cost of tlie raw food. of service, and other running eXpenses.
 l A careful study of school-lunch problems should be made in every school starting such work. as It Is of | the greatest importance that the lunch should be developed along the broad est possible lines. The cooperation and interest of the entire community are necessary, and the interest of the school boys and girls themselves should be aroused and maintained in every conceivable way. Good organi- | zatim Is necessary for successful work. The problems O; organization and administration are here discussed. while the food problems themselves nre not considered In detail. Valuable references on diet are available. and a selected list of these Is given for the heneft of teachers who wish 10 inform themselves in regard to all as- poets of the work. The knowledge. the Interest and the enthusiasm of the teacher will determine the success of the undertaking.
