the opposite side of the road. Coalhill, Knock Jargon, and 

 Knockrivock mound forts were then visited. At Bankhead a 

 clump of Sedum Telejjliium, L., was observed. Senecio eruci- 

 folius, L., grows near the boundary between Ardrossan and 

 Kilwinning, on crossing the Monkcastle Burn. Mr. D. A. Boyd 

 reported observing the following microfungi : — Uromyces 

 alchemillce, Pers. — uredospores on Alchemilla vulgaris; Puccinia 

 hunii DC. — on Conopodium denudatum ; Uredo scolojyendri,

Shewalton, 20th May, 1905. — Joint with the West Kilbride 

 Natural History Society. — The party, who numbered about 

 twenty, travelled by rail to Dreghorn, and walked to Drybridge 

 and Irvine. Through jjermission kindly granted by Mrs. Kenneth, 

 access was obtained to the policies and gardens at Shewalton. 

 The gardens contained some fine species of Azalea and other 

 ornamental shrubs in bloom, while the collection of herbaceous 

 plants included several varieties seldom seen in private collec- 

 tions. In the woods, &c., numerous microfungi were noted, 

 including Uromyces poce, Rab. (as ^cidium), and U. ficarice, 

 Schum., both on Ranunculus Ficaria ; JEcidiwm albescens, Grev., 

 on Adoxa Moschatellina ; Puccinia bunii, DC, on Conopodium 

 denudatum, &c. In the course of the walk from Shewalton to 

 Irvine, Mr. John Smith conducted the party for some distance 

 along the river - bank, and pointed out various features of 

 geological interest, including a large shell-bed through which 

 the stream has cut its way. Numerous specimens of Scandix 

 Pecten, L., were observed growing on the river-side, while 

 Teesdalia nudicaulis, Br., occurred in sandy places on Shewalton 

 Moor. The following trees were measured, viz. : — Gean (Prunus 

 Avium, L.), 5 ft. 7-^ ins. in circumference of trunk at 3 ft. 6 ins. 

 from the ground, with a bole of 5 ft.; Beech (Fagus sylvatica, 

 L.), 1 1 ft. at 5 ft., bole 11 f t. ; Copper Beech (Fagus sylvatica, 

 L., var. atro-virens, Duroi), 6 ft. 5 ins. at 5 ft., bole 20 ft., and 

 another of 6 ft. 0| ins. at 5 ft., bole 12 ft. The rocks near 

 Shewalton belong to the carboniferous period, and consist of 

 sandstones, shales, coals, &c. Of later date is a small tract of 

 agglomerate exposed in the River Irvine at Shewalton Mill. It 

 is apparently the neck or stump of a volcano, and is probably
