March. — During March vegetation made only moderate 

 progress ; the weather during the month was exceedingly 

 variable. Very severe frost occurred during the first week, 

 but the total amount for the month was rather below the 

 average. Eain, sleet, or snow fell more or less on fourteen 

 days, but the ground was in such a dry condition that little 

 impression was made thereby. Spring-flowering bulbs are 

 fully up to the average in richness and quantity of blossom, 

 but it is evident that many herbaceous and shrubby plants 

 have suffered severely this winter, not so much from excess of 

 cold as from the insufficient ripening they received during the 

 past cold summer. The thermometer was at or below the 

 freezing-point on sixteen mornings, indicating collectively 90 

 degrees of frost, as against 131 degrees for the corresponding 

 month last year. The lowest readings occurred on the 2nd, 

 24° ; 3rd, 22° ; 4th, 16° ; 14th, 29° ; 27th, 23°. The lowest 

 day temperature was 39°, on the 1st ; and the highest 59°, on 

 the 13th of the month. Of the forty spring-flowering plants 

 whose dates of flowering are annually recorded, the following 

 fourteen came into flower, viz. : — 



On the rock-garden sixty species came into flower, being 

 f(Hir less than for last March. Amongst the most conspic- 

 uous were Chionodoxa Lucilia^ and sardcnsis, Coptis hrachy- 

 pdala, Uc'idaria pcntapliylla, Drula Mawii and hrunio'folia,
