PRACTICAL ARBORICULTURE 279 
To collect seed of pure speciosa costs $3.50 to $5.00 per pound, while seed 
from low-growing, inferior trees may be gathered for ten cents per pound; 
hence the incentive to secure cheap seed. 
The author, some years ago purchased seed from the tenant of the Yagg 
plantation at Hutchinson, Kansas. After waiting four years we found the 
entire lot to be bignonoides hybrids. 
We afterwards collected seed and pods in this noted Catalpa farm, which 
we photographed, and reproduce below. No intimation was ever given by the 
Forestry Bureau that these trees were other than speciosa, although they 
spent months examining it.
