years’ ley, and an infusion of it will not be found amiss in 
permanent pasture mixtures. 
Tall oat grass is a plant of such rapid growth, that it is 
naturally exhaustive to the soil, and, although sown in the 
spring, early autumn is its natural time for seeding, hence it 
constitutes an excellent renovator, and if it takes in the 
autumn, it will produce good crops during its first summer. 
With tall oat grass a difficulty will always be found 
apparent, it likes to be buried deeper than most grasses, and it 
will be noticed that the grass springing from holes, cracks, or 
deep crevices, where it has found a lodgment previous to the 
action of the roll, will spring up strongest and best. 
It is a very hardy plant, and well worthy of attention, 
although its seed cannot be called cheap. 
Curiously enough it seems to thrive on the most exposed 
situations near the sea, and on wild places where only the 
coarsest herbage, rushes, or heather finda home. It'is, how- 
ever, amenable to cultivation, and will respond to sewage 
treatment, although such must be used with caution. 
An imperial bushel of the seed scales about 14 1b., and a 
pound produces some 450,000 germinating seeds. 
YELLOow OaT Grass (AVENA FLAVESCENS, LINN.). 
This species thrives best on light soils having a chalk 
sub-soil, and sheep and cattle are exceedingly fond of it. 
It is not an early grass, and is more adapted for grazing 
than it is for hay, as it produces a quantity of pale green 
herbage late in summer as well as in the autumn; itis a most 
useful grass to sow on inferior soils, as it does not require a rich 
feeding ground, and it will go on growing and throwing up 
conspicuous golden flowers when other grasses are comparatively 
stunted. 
Its seed is of a light frothy nature, and somewhat deficient
