MONTHLY AGRICULTURAL REPORT. 
“ Tuts is the coldest and most backward spring within the memory of man.”” Such 
is the norma loquendi, the invariable phraseology adopted on every similar occasion. The 
present backward spring, or burning summer, is always the most backward ‘and the most 
ardent of any predecessor. But we, who have passed through very many cold and ungenial 
springs, with sufficient fretfulness at their retarding and probable future ill effects on vege- 
tation, have also witnessed many of a character, in these respects, fully equal to the — 
present. 
progress, and some real damage will have been sustained, but hitherto of no material con 
sequence. Should, however, the present ungenial easterly winds continue yet for any con- 
siderable length, it may be hoped not a very probable case, much damage to all the crops’ 
must inevitably result. On the other hand, a favourable change, and continuance of season- _ 
able spring weather, will leave us little to regret, since, sometimes, a backward spring is the 
harbinger of a plentiful harvest. The early part of the present month gave us hopes, from a, 
few days of mild temperature, with south-western breezes; when, suddenly, the wind 4 
changed to its old quarters, north-east and south-east, accompanied with storms, and rain, 
and an uncomfortable and chilling state of the atmosphere, which yet remains. 
Until the above change, the land had worked admirably, even the most rough and in- 
tractable clays, and the barleys and other remaining spring crops were getting into the 
ground with the utmost expedition, and in the most husband-like manner, when the con- 
siderable quantity of rain which fell, reduced the low and heavy lands to such a stateas to. 
arrest the course of semination, and to render it almost impossible to cover the seed already 
spread: Many breadths of such land have been actually flooded, particularly where drain- 
ing has been defective ; a defect, we regret to say, of too frequent occurrence. On the 
light, high, and exposed soils, the tender and chilled wheats, much of them have been 
actually blown out of the soil ; and even the strongest and best wheats, do not exhibit that 
healthy and blooming luxuriance appropriate to a genial season. The early sown spring 
crops are still more affected by the dampness and chilliness of the air, especially by night, 
when frost, and even snow, have not been uncommon. As to be expected, the ill effects 
of this unfavourable season have been most severely felt in the northern parts of the 
country, where, in consequence, the spring seeds will be put into the ground more than 
usually late. The grass, though it retain a good colour, at least in this country, is to» 
backward to afford a bite to any kind of stock, whence the late boasted superabundance of 
hay, must have received considerable help towards its reduction, and the turnips. which 
have endured the season, must have come into requisition. The young clovers, which 
were advancing with so much luxuriance, have received a considerable check. Potatoe 
No doubt, all the earth’s productions have been inordinately delayed in their —
