Steel operations dropped to as low as 4 8 % of capacity in April, recover­ing to 7 3 % at year 's end. Currently die rate is around 8 3 . 5 % .

As a nitrogen fertilizer material, am­monium sulfate ( 2 1 % N ) is slowly yielding ground to other nitrogen prod­ucts of higher analysis, especially ni­trogen solutions.

Synthetic ammonium sulfate output was s tepped up in 1958 but not enough to compensate for production losses at the coke ovens. The outputs, based on data supplied b y the Bureau of Mines and the Bureau of the Census, with

• Exports H e a v y . Exports assume an important vo lume in ammonium sul­fate. I t is es t imated in the t rade tha t the greater pa r t of the synthetic pro­duced in 1957 and 1958 was exported. A good share of t h e coke oven sulfate in 1957 was also sent abroad, b u t out­puts from this source in 1958 provided little surplus for th i s purpose.
