The ideal materiat for prolonging the life of old 

 roofs. I.F.S. Roof Coating stops leaks, fills nail holes 

 and broken seams. Made from asphalt and asbes- 

 tos and contains flake-graphite. Easy to apply. 

 Saves the cost and labor of a new roof. 



This quality paint it a favorite with Illinois 

 farmers. It protects the surface and improves the 

 appearance of barns, sheds, corn cribs, and 

 other farm buildings. 



SOYOIL RED BARN PAINT is made from rich, 

 red iron oxide and especially refined oils which 

 penetrate and protect the surface. Makes any 

 barn look better and adds years to the life of 

 outside walls.

The wet and cool weadier of April and 



May has prevented much shippin/; and 

 spreading of limestone and one result has 

 been the building; up of sizable storage piles 

 of limestone at several of the larger quar- 

 ries. 



"The use of liming materials reached an 



all-time high for 1944, the total amount used 

 being estimated at 64,842 tons. This is 

 still below the amount that should be used 

 annually to keep our soil in the most pro- 

 ductive state according to our agronomist". 

 This is a quotation from Pit and Quarry 

 magazine and is not for a county but is 

 for the state of Connecticut. Several of 

 the smaller eastern states are listed with 

 usage of agricultural limestone in 1944 over 

 100,000 tons. 



Can limestone test over 100 per cent 



Calcium Carbonate -Equivalent? The answer 

 is "Yes", for the yardstick or measuring 

 device is calcium carbonate limestone which 

 when pure has a C.C.E. of 100 per cent. 

 There are deposits of limestone in some 

 parts of the state in which magnesium car- 

 bonate has replaced part of the calcium 

 carbonate and hence is called dolomitic 

 limestone. The magnesium carbonate has 

 a somewhat greater ability to neutralize 

 sour or acid soils (almost one-fifth more 

 by weight than calcium carbonate). We 

 may have native rock containing up to a 

 maximum of 45 per cent ma£>nesium car- 

 bonate which with 55 per cent of calcium 

 carbonate would make a sum total of 100 

 per cent but a Calcium Carbonate Equivalent 

 test of approximately 109 per cent. This, 

 however, is about the top test obtainable 

 from the natural limestone rocks of the 

 state.
