Manufacturing and Mining Out put Increases 2SO Per Gent

Chicago, Jan. 2S.-The manufactur-
 ing and mining output of the United
 States is at present 230 per cent
 greater than it was 20 years ago, ac-
 cording to the first report by the re- search council of the national trans portation institute, made public here Despite shortened hours of labor, the country enjoys so per cent per capita more manufactured goods than in 1900, the report said.
 Tn agriculture, increased use of capital and development of more eff cient methods made possible an out put 3S per cent greater with an increase of less than , per cent in the number of workers" continued the report, which is made by Edgar E. Clark, chairman of the council and former chairman of the interstate commerce commission. This main tained the food supply of the nation and the export surplus. and left the great mass of additions to the work ing population free to engage in min- ing, manufacturing, trade and trans portation.
 As d consequence the workers en- gagged in manufacturing doubled. while the mine workers increased 70 per cent. These two industries with the help of 0o0.000, ,000 new capi- tai. added to the St1.000. .o00,0 ,000 al- ready invested in them in 1899, pro- dueed @3o per cent of the volume in 1900.
 Transportation became more ac- tive function than ever before. The average distance per ton increased 25 per cent Revenue ton miles almost trchled. This transportation service was accomplished with barely twice as many workers as in 1900 and with an addition of S9,575, 000 GOO to the s10,~ a6a, ,0o0,no0 represented by the indus try in 1900.
 Prom the standpoint Of the con- sumner We find that the capital charge Der unit of output in manufactures and agriculture has more than dou- hlcd: in mining it has increased by cne-third. while in transportation II Is smaller than it was two decades ago.
 While the number of persons en- gagged in farming has increased but per cent the farm products output las practically kept pace with the EfONfn III our ibihis'ib'As 's'tN'' l'@' son engaged in farming produced i3a units Of product in 1920 as against loo twenty years earlier
 ''It is this increase in the efficiency of agricultural production which has made available for the other indus fries almost the entire l2,6oo.enh workers added to our population tn the last sH years Besides doubling /. fhe number of workers In manutae- . turns, increasing the number of mih- 1 prs 1o per cent and doubling the . transportation force of fhe country l some t. e68, ,Bo6 people were added to . the building trades, the electrical tn- I anstriea banking and finance, trade . and professional service.
 For every l09 tons of freight fransnortrd in 1900, We transported . a34 in 1920. The 1920 revenue ton . miles were 2g2 per cent of those Of . 1900. Passenger miles increased in 1 fbe same ratio. Of the national tn- rnma of 1922, s4,00O ,00b. o00 was paid . for railroad freight transportation. , This constituted about per cent or uur total income. This ratio ol an annual freight bill Of 6 per cent has Ifmained practically constant since igh6.
 Increase of capital per unit Of out nut differs widely in the four major industries. 1a manufactures the capl- tai involved in producing unit of ortput in 1920 was s2,t3 as against si in 1900. Railroad invested capital per unit of output was s27T in 1920 . .s against st in 1900, while in mth- jug fl was s1.31."
