7. We have planted seedlings of native chestnut as far as we 

 have space in our own plantations, and have interested others in 

 this work, in the hope of developing individual Americans which 

 show some degree of disease resistance. This last fall we re- 

 ceived nuts of the native chestnut from 7 states. 



8. We have continued breeding the various species and hybrids 

 together in the hope of developing a disease-resistant stock of tim- 

 ber chestnut.
