the very small percentage of organic matter as compared 
with the Boston greenhouse soil. The Ashtabula soils 
are famous for their production of lettuce and cucumbers, 
and tomatoes are also grown to a considerable extent in 
this soil. 
Cleveland soils.—The best vegetable forcing soil of the 
Cleveland district is known as the Dunkirk fine sandy 
loam. Although not quite so coarse in texture as the 
Dunkirk sandy loam used at Ashtabula, it is highly 
satisfactory for the growing of lettuce and tomatoes. 
Cucumbers are also grown in this soil to some extent. A 
mechanical analysis shows the following results:

Toledo soils—The typical trucking soils of the Toledo 
district belong to the Miami series. The Miami sand is 
best adapted to vegetables. It is variable in composition, 
but contains, according to mechanical analysis made by

Lansdale silt loam.—Tomatoes are grown quite ex- 
tensively in this soil, near Lansdale, Pa. It is regarded 
as a good soil for general farm crops. The drainage is 
good and the soil does not puddle very easily. The 
following is a mechanical analysis of the soil:
