DEYEUXIA FORSTERI. . 
. ©. Crarxe, Helidon.—The grass you sent for identification is thus 
described by Mr. F. M. Bailey, Government Botanist :—Deyeuxia Forsteri, 
Kunth.—This is a quick-growing grass, springing up with the slightest shower 
of rain, especially during winter, but at the approach of summer its light 
panicles break off and are seen blown about in all directions. One or other of 
its several forms may be met with throughout Southern Australia and New 
Zealand. Useful on account of giving a bite of feed in winter and early 
spring. 
[Your letter was addressed tothe Agricultural College instead of to the Department of 
Agriculture ; hence the delay in replying.—Kd. Q.A.J.4 
COMMERCIAL BUTTER. 
In the September issue of the Journal, Mr. H. H. Seaborn, Beaudesert, 
asked which of two cows would give the greater amount of commercial butter 
fat, which we took to mean “commercial butter,” there being no such thing as 
‘commercial butter fat.” By some remarkable error the answer was given 
that one of the cows would yield # lb. more than the other. This was an 
obvious misprint, as the quantities of milk together would not yield so much. 
The correct answer should have been, as worked out by the dairy expert to the 
Department of Agriculture and by Mr. R. E. Davenport, of Mudgeeraba, +3, 
Ib. in favour of No. 1 cow. 
OATS AS ENSILAGE. 
W. H. Dysatr, Greenbank, Yandaran.—I have a quantity of oats, and I 
should be glad if you would, in the next issue of the Journal, reply to the 
following questions on converting it into stock ensilage :— 
(Juestion 1.—At what stage should the oat crop be cut ? 
Answer 1.—Oats cannot be cut too green for the ensilage stack, pro- 
vided the crop has reached the earing stage. 
Question 2.- Should it be carted at once, or left on the ground for a 
while ? 
Answer 2.—It should be carted at once. 
Question 3.—How much should be put on the stack each day ? 
Answer 3.—About 10 feet a day. Then stop operations for a day to 
allow the forage to settle down. 
Question 4.—If wet with rain, can it be stacked ? 
Answer 4.—Yes. If you have a quantity cut, stack it quickly regard- 
less of weather. 
Question 5.—What is the smallest stack advisable to ensure good 
ensilage ? 
Answer 5.—A square stack 10 feet by 10 feet, holding 20 tons, is 
small enough. The smaller the stack, the greater the waste at the 
sides. 
Question 6.—What pressure is needed, and how is it to be applied ? 
Answer 6.—No pressure is required. Experiments have proved that all 
the complicated screwing down appliances are needless. 
Question 7.—Would the stack require any cover? 
Answer 7.--Yes. Cover the stack with straw or any other available 
material. Stretch a couple of wires over it to keep it in place, and 
weight with a few stones to keep it from being blown off in a gale. 
A stack 14 feet by 14 feet will contain 100 tons. One ton of green oats 
will make 1 ton of ensilage. One cubic foot of ensilage weighs on an average 
45 lb.
