CODLIN MOTH AND BATS. 
Tur California Fruitgrower recommends the encouragement of bats in the 
outbuildings, and quotes Dr. C. F. Hodge, of Clark University, Worcester, 
Mass., who says that in an orchard near his home he found nine grubs of the 
codlin moth in one minute. Chancing to visit another orchard not a mile from 
the first, he found only four grubs in an hour's search. The owner of the 
farm said that in an old barn near by lived severty-five to 100 bats, and his 
apples were always free from worms. ‘The naturalist caught a bat, and 
offered it some of the grubs, which were greedily accepted. The codlin moth 
flies only at night; so does the bat: good circumstantial evidence that the bat 
is a useful friend to the apple-grower. 
Dr. Hodge took half-a-dozen bats home, and kept them in the parlour. 
They made their home in the top folds of the window draperies, flying about at 
night and sometimes in the daytime. From time to ume, netfuls of night- 
flying insects were released in the room, and never a bug remained in the 
morning. The bats took everything, from a spider to a polyphemous moth. 
One morning the doctor counted while a bat devoured sixty-eight house flies. 
A REMEDY FOR ORANGE RED SCALE. 
Mr. R. Hasenerove writes to the Adelaide Observer as follows :— 
A. few months ago you published a recipe for killing Red Scale on orange 
or lemon trees. It was 10 lb. of resin, 2 Ib. of soft soap, and 5 lb. washing soda 
put into 54 gallons of water, and boiled fora given time. My trees being badly 
affected I made up the mixture, but added to it sixpennyworth of quassia. 
After spraying the trees the foliage came off, and young shoots were aifected. 
T added three times the quantity of water, and found it very effective. The 
scale has quite disappeared. Before my apple and pear trees came out in leaf 
‘I sprayed them with the strong mixture, and when in bloom I sprayed with 
the reduced strength. I think one trial does not prove the application to 
be aremedy. Last year, however, the difficulty was to find fruit not affected, 
but this year the disease is very limited. 
A NEW WAY TO TELL A GOOD COW. 
“ Nonrru Somerset” writes to the Mark Lane Express:—As science advances, 
more and more attention is given to details, and it is found that often what 
are popularly considered to be very minor points often turn out to be some- 
thing of the greatest importance. As is well known in farming, to produce a 
good milker is considered to be somewhat of a lottery, and many a calf is reared 
for dairy purposes that would have been far more profitable converted into 
_ beef. Now, how are we to pick out these? I glean froma Swedish dairy news- 
paper—WMejeriernas Annonsblad—that a discovery has recently been made, the 
truth of which has been proved by a first-class veterinarian, that makes it quite 
possible at the birth of a calf to Judge whether it will become a good milk cow 
or not. It has been observed that the palps that are on the inner side of the 
cheeks near the corner of the mouth have different forms, according to whether 
the animal is a good, a middle class, or a very indifferent milker. The palps 
being large, broad, and flat denote that the animal gives a large quantity of 
milk. If they are only round, the milk qualities are of the most ordinary 
description; while if they are oR the milk yield is of a most wretched 
description. Here is a chance for some English farmer, who keeps a record of 
the milk production of each cow, to put this statement to the test. f 
A QUICK-GROWING WINTER FODDER. 
Mr. H. A. Tarpent writes :— 
The other day I received from an enterprising seedsman a small packet of 
Skinless or Nepaul Barley, which he recommended should be tried as a great 
and valuable novelty. The receipt of that packet induces me to believe that 
the plant is not yet so well known amongst farmers as it should be.
