was uniform and intermediate. In later generations erratic segregation was 

 obtained, with different sizes of flowers on the same plant, and frequently 

 different lengths of petal in the same flower. Since the behaviour is not 

 Mendelian it may be due to the distribution of cytoplasmic differences.

20. Di'- A. W. BoRTTiwicK. — ¥ar>ii Foresfry. 



The object of this paper was to call attention to the neglect in this country 

 to turn to greater advantages, both direct and indirect, what in the aggregate 

 amounts to a large area of land regarded as waste places, scattered about on 

 farms, even in the most arable districts, such as banks, knolls, precipitous 

 declivities, hollows, marshy places, &c. Trees will grow in such places, and 

 produce fencing material and many other timber requirements of the farm. 

 They will grow where no other crops will grow. They encourage the growtli 

 of other crops on adjacent lands by the shelter they afford. They effect an 

 ameliorating influence on the local climate, and stock of all kinds thrive better 

 on farms with properly located plantations in the form of shelter belts, clumps, 

 and roundels. Attention was also called to the injudicious practice of over- 

 crowding hedgerows and roadsides with timber trees as well as the toleration of 

 single trees in arable fields.
