FIELD AND FAI'M. (From ihs AgrlsnRitral Gazette.") I TIm" FLY." j IS ever have I known (remarfe3 Prof. Wrightsoiii the turnip dy more destructive than during last month! One piece of turnip, 12 acre3 in extent, has now bees driiied for the third time, and other fields are sadlj tormented by thi-s pin-pricking, pertinacious little foe The mischief is quickly done, and constant watchful- ness is required in order to be certain as to whet her the seed has germinated and the young plants have disappeared, or whether the seed has still to come. Like all insect attacks, it is difficult to fi"ht, and many of the entomological remedies are of such a nature as to render them inconvenient and ex- pensive. There are, however, means for evading or combating the fly. The tarred board, or board on lo%v wheels, tarred on the under side, is an old plan which was approved by the late Professor Buckinnn many years ago. It was never widely adopted, on account of its uncertainty of action. If the fly could be always induced to jump against the tarry surface the success would be perfect, but if he resists the tempta- tion, or jumps downwards instead of upwards, or sails in jumping quite high enough, he escapes. I have been experimenting upon the paraffin drag, and am pleased with the result. About t part paraffin to i water is a suitable proportion, and by offering a small; increase in pi:v and sending Itip two horses, one to rest the other, 27 acres were done in one day. The effect was very marked, as scarcely a fly was to be seen on the following day. They appeared stupe- fied by the paraffin, and ceased to plague the young plants. Another piece which was threatened with extermination is now easily seen in row from end to end of the fleM, and will be soon fit for hoeing. This is a simple means of fighting the fly. A twelve- foot rail, with any old fabric nailed on whole or in strips, is required. It resembles a flag drawn by the staff crossways over the surface, and is kept moist with paraffin and water. It is light work for a horse, and the cost is not appreciable. The effect is, how- ever, immediate, and deserves to be tested and re- ported upon, so that the plan may be generally adopted or abandoned, according to results obtained. CHARLOCK SPRAYING. The use of paraffin for turnip fly has some resem- blance to spraying charlock, which seems this season to be again in the ascendant. The trials made by the Yorkshire College are declared to be eminently suc- cessful, and experience teaches that the charlock is most successfully treated when very young. Charlock spraying is not quite so easy to put in practise as might at first appear. The difficulty of providing water on the dry uplands when the weed is most rife the objection to taking horses from the press- ing work of root cultivation at the busiest time the cost of purchasing sprayers, and the uncertainty which still hangs over the process, are all deterrents. Besides, when charlock is in the early stages of growth it is a question not to be too rashly dismissed whether it may not be equally well destroyed by har- rowing. When young corn is seen to be invaded by the small cotyledon leaves of the charlock a fine- toothed harrow will draw them by the million, and expose their white filaments to the sun and air. Charlock is often very erratic in its germination. In some cases it refuses to show itself, although land may be ploughed and harrowed and left for a period which ought to suffice. After the farmer's patience is exhausted, and the land has been drilled, then the weed will appear in countless numbers, and threaten to smother the crop. In a case now before me, part of a field was early ploughed and harrowed, and the sharlock still refused to come. After drilling with turnips I see it is covered with seedlings of charlock. The other half of this field was ploughed and drilled without waiting a day, and there the turnips are is row, and no charlock is yet to be seen. It is diffi- cult to know what to recommend in such cases- whether quick drilling, or waiting for the appearance of the charlock. POULTRY-FEEDING EXPERIMENTS. We have received from the Hon. James Wilson. Secretary of the U.S. Department of Agriculture, an elaborate report by Messrs. J. H. Stewart and H. Atwood, of the West Virginia Experimental Station Dn certain poultry-feeding experiments. The following is a summary of the essential facts: The teats were on the effect of nitrogenous and carbon- aceous rations for laying hens, floored v. unfloored poultry houses, and the effect of age of fowls upon egg production. Two test s-nitrog en otis v. carbonaceous rations- were made. In the first, six lots were used, with from 10 to 20 fowls in a lot, representing three different breeds. Lots 1 to 3 were fed the nitro- genous ration, consisting of middlings, linseed meal, I ground oats, and corn (Indian) meal in varying pro- portions, together with ground fresh meat and bone, while Lots 4 to 6 received the carbonaceous ration, of which corn meal was the principal constituent. In addition, all the lots had either boiled potatoes or steamed clover hay, and at night all the whole grain they could eat up clean, consisting of corn, oats, and wheat screenings, corn pre- dominating for the lots fed the carbona- ceous ration. The test covered seven periods of 30 days each. The financial results are elaborately tabu- lated, but with the details it is not necessary here to deal. Suffice it that the net profits per 100 hens from the lots fed the nitrogenous ration was within a fraction of JE20, and from the lots fed the carbona- ceous ration E4 3s. The effect of the two kinds of rations on the fertility of eggs was tested in incuba- tors, and 66 per cent. of the eggs produced on the nitrogenous ration were fertile, and 47 per cent. of the carbonaceous ration only. The average weight per 100 of the former eggs were 12"681b., aud of the latter, ll'571b. only. The second test was made with four lots of white Leghorn chickens, each containing 10 hens and one cock. Lots 1 and 3 were pullets, lots 2 and 4 old fowls. Lots 1 and 2 were fed the nitrogenous, and Lots 3 and 4 the carbonaceous ration. The test covered seven periods of 30 days each. All the lots were fed a mash of ground feed in the morning, lots 1 and 2 receiving meat meal in addition during the first four periods, and ground fresh meat and bone during the remainder of the test. During periods two, three, and four all the lots were given boiled sugar beets, but, as the beets seemed to be making the fowls too fat, they were then dropped from the ration, although the fowls were very fond of All the lots were fed at nivbt as much grain as they would eat up clean. The results were calcu- lated per 100 fowls. On this basis lots 1 and 2 weighed 227 and 3041b. at the beginning of the test, and 272 and 273 at the close; while lots 3 and 4 weighed, respectively, at the beginning 213 and 263, and at the close 250 and 3001b. Calculated per 100 hens, the fowls fed the nitrogenous ration laid 7555 eggs, and those fed the carbonaceous ration, 3431. Two trials were made in the test of floored or un- floored houses. The first included six lots, represent- ing Black Langshan, Brown Leghorn, and Blue Andalusian breeds. Lots 1 to 3 were placed in pens in a portion of the poultry house which was floored with rough boards from 2 to 3ft. above the ground, and the other lots were kept in pens in the unfloored portion. The grain ration fed varied somewhat dur- ing the five months of the test, but was uniform in all the lots. The conclusion is quite remarkable, and is thus summed up by the reporters The three flocks kept on the floor laid 10,859 eggs (calculated for 100 fowls), while those on the ground laid 13,918. The result was quite contrary to expectations, and can be explained only by the fact that the unfloored pens seemed to be somewhat warmer than the others, as the water in the drinking dishes in the floored pens would sometimes freeze, while in the unfloored pens it seldom did so. Quite contrary to expectations also, the health of the fowls in the anfloored pens remained almost perfect during the entire test. Only two fowls died of the roup-one from a floored, and the other from an unfloored pen. There was no other sickness of any kind." The comparative egg production of pullets and old hens was tested with white and brown Leghorns, ten hens being three to four years old. The test with the white Leghorns began on October 19, and covered seven periods of 30 days each. The brown Leghorns were fed for four periods of 30 days. In both cases the nitrogenous food mentioned above was given. The three lots of pullets, calculating results per 100 hens, laid during the test 6209 eggs, and the old hens 6349. It should be added that the three lots of pullets gained 1431b. in weight, while the old hena only gained 841b.
