The plans and trees were furnished by the Division of Forestry, and 

 the expense of setting was divided. The plats were located upon the 

 old College farm, on ground adjoining the first tree experiments under- 

 taken by the College. The soil is much the same, very poor and 

 gravelly, sloping to the south and east. 



Table XIII shows the species planted and the grouping in plats. 

 Some seeming contradictions in the table are accounted for by the 

 record that in 1898 there were used in replanting 1107 Bull pines, 

 1696 Scotch pines, and 3004 Austrian pines. 



It will be noted from the table that in 1900 the surviving trees 

 were largely of the species .which have been in some degree success- 

 ful in previous plantings. At present (November 1903,) the count 

 is much the same as in 1900. A few feeble individuals failed to sur- 

 vive the trying summer of 1901. but for the most part the appearance 

 of the trees during and after the prolonged drought was very gratify- 

 ing. 



Notes dated March 1898, and February 1899, state that the elms, 

 oaks and catalpa were seriously injured by rabbits. A considerable 

 number of these have made new growth from the roots and are now 

 fairly thrifty trees. 



In the severe winter of 1898- ? 99 nearly all the catalpas were killed 

 to the ground. Since then many of the trees have by flower and fruit 

 been identified as the common catalpa, Catalpa catalpa, formerly C. 

 bignonioides, and not the Hardy catalpa. C. speciosa. 



The artemisia, probably A. abrotanum, has been removed from the 

 plats, where it was used as a nurse crop ; in most cases where the 

 trees made good growths it was overgrown and died. 



Where the aspens have seemed to be crowding the permanent trees 

 they have been removed. Table XIV shows the growth of an average 

 block of twenty-five trees. As a tree it is probably of little value.
