Kepresenting as they do much of the lower peninsula these figures are 

 of great interest and importance to the future welfare of the common- 

 wealth. They show that out soils are not high in phosphorus. A soil 

 that contains a total of about 2000 pounds of phosphorus per acre to a 

 depth of seven inches is considered to be well supplied with this element 

 of plant-food. The pine and scrub oak lands usually are extremely low 

 in this substance, the prairie soils are highest and others occupy an inter- 

 mediate position with respect to their phosphorus content.

 bundles on the right in each group were grown on land receiving 200 lbs. per acre of IS
