TRINITY COLLEGE 229 



near the ground, girths 4 ft. Mr. Raper informs me that it 

 was planted about 1889 and was originally a Golden Catalpa 

 (with larger leaves, grafted on to an ordinary stock), but was 

 broken one night by undergraduates below the graft. It 

 has grown rapidly. The young Birches near the Lodge now 

 measure about i ft. 9 in. 



BALLIOL COLLEGE contains the wreck of the largest Mulberry- 

 tree in a College garden. The short hollow trunk has a 

 girth of 7 ft. 10 in., but is not strong enough to support the 

 branches without the assistance of props. A younger tree, 

 planted by Mr. Woollcombe, girths 3 ft. n in. ; and will in time 

 take the place of the large one. Near by, the Ailanthus 

 measures 4 ft. 6 in. round the trunk. The third Mulberry was 

 planted in 1875, an( ^ tne Lime in the. following year. The 

 latter tree has done well, its present girth being 3 ft. 6 in. 

 Near the Hall is a Weeping Cerasus virginica. The big Plane 

 measures 1 1 ft. in girth. 



The present Bursar, Mr. Edward Hilliard, has much in- 

 creased the interest of the collection by adding the following 

 trees, several of which are not to be easily found elsewhere in 

 Oxford : 



In 1906. 4 Wistarias on the Old Library. 

 In Dec. 1908. 9 free-flowering sorts of espalier Apples, and 

 Catalpa bignonoides, Cerasus serrulata, 



aurea, Amelanchier ovata> 



Crataegus prunifolia^ Euonymus latifolius, 



C. macrantha, Viburnum plicatum (dead)- 



These trees were chosen because they flower in or about the 

 last week in May. 



In 1909. Birch in the Back Quadrangle. 



In 1910. 2 Hornbeams in the Back Quadrangle, and 



Cotoneaster frigida . 

 In 1911. Ceanothus veitchianus. 



Magnolia soulangeana, by the steps of the Hall. 

 Davidia involucrata, a plant not well-known in Oxford.
