68 THE CANADIAN HORTICtlLTTTEIST. 



these fruits Avere at the time just in the condition to be most seriously 

 and generally injured by a frost. In tlie case of the grapes, the young 

 shoots were out from six to twelve inches long,'fully exposing the 

 young tendrils covered with fruit germs, and of course very tender and 

 most easily affected. In the case of the strawberries, the corolla and 

 calix were still pointing upwards, placing the young and tender germs 

 in the condition to be most seriously affected by frost. In consequence, 

 we shall suffer in both these crops ; and there is considerable com- 

 plaining throughout the country. Currants and gooseberries too, 

 whose fruit was nearly grown to full size, were severely injured also by 

 the frost, I think fully to the extent of one-third the entire crop, 

 raspberries and blackberries not being quite forward enough to be so 

 easily injured, escaped the effects of the frost. Apples, pears, cherries, 

 plums, and peaches, although each of them was slightly affected by the 

 frost, yet in the case of each, the promise at the present is for a most 

 abundant and unusual crop. Every tree nearing maturity was literally 

 covered with blossoms, most of the genus being fertilized and setting 

 very thickly over the trees. But this is not true of those trees that 

 were defoliated by the tent caterpillars last season; no blossoms what- 

 ever appeared upon them. I might mention also that the effects of 

 the frost were so severe as to totally kill young Tent Caterpillars on the 

 leaves of our young trees; also the young and tender growtlis of Nor- 

 way spruce and balsam fir were seriously frozen and killed ; so of 

 black and white walnuts, chestnuts, hickory, &c. Our grains, and our 

 gTasses, in their young growths, liave also suffered, and are severely 

 injured in their leaves, and the stems of clover were frozen. This is 

 a very unusual occurence, but then this whole season has been a very 

 unusual and remarkable one from the beginning. 



With respect to insects, allow me to report that they are at the 

 present time very abundant, and very industrious and exceedingly des- 

 tructive in their effects upon our young foliage. Tlie Winter and 

 Spring has been the most favorable for the preservation and develop- 

 ment of insect life. 



I wish to report that the Currant Worm, (Nematus Yentricosus,) 

 is unusually abundant this season, and even now many gooseberry and 

 currant bushes are totally denuded. We first observed them working 

 April 25th, and most abundantly on the gooseberry leaves; and by
