GENERAL CONDITIONS

The sales of lime manufactured in the United States in 1923 were 12 per cent greater than those of 1922, which had shown an increase of 44 per cent over those of 1921, a year of depression in the building and chemical industries of the country. All the principal producing States except Maryland showed increases in production in 1923. The quantity of lime sold for construction work and for chemical use increased, but that sold for the liming of land decreased. The number of plants reporting operations was 63 less than in 1922. This

decrease was principally in Pennsylvania, Virginia, Maryland, and West Virginia, where lime is burned by farmers or small operators for local consumption. Production of this type has been falling off for several years, on account of the cost of fuel and scarcity of labor. Ohio retained her position, established in 1922, as the leading State in the production of lime, and Pennsylvania ranked second. The growth of the industry in Ohio is due chiefly to the increased output of hydrated lime used for building. In Pennsylvania, which was prior to 1922 the leading State, there has been during the last few years a decided decrease in the output of lime manufactured for use in agriculture and insufficient increase in the sale of lime for chemical and structural uses to offset this loss. During 1923 many improvements were made at plants and kilns in order to reduce the cost of labor to a minimum and to increase efficiency. Wages were high throughout the year, and at times, especially in the summer, common labor was difficult to obtain. The cost of operation was generally higher than in 1922, although coal was more plentiful and somewhat cheaper.

cheaper. The average value, at the plants, of lime sold increased from $9.14 a ton in 1922 to $9.81 in 1923, although many reports showed prices about the same or lower than in 1922.
