Of course, a good loam soil provides better growing conditions than either extreme. The important factor in soils from a chemical standpoint is the pH value; that is, whether they are alkaline, acid or neutral. This indicates whether lime is needed to improve growing condi- tions. Other laboratory tests are made to measure the plant food content of a soil, such as amounts of nitrogen, phos- phorus and potash. These tests, how- ever, have little practical value since they do not show whether such ele- ments are present in forms that can be utilized by plants. When Tests Important. To have a soil test made involves some effort in preparing the sample, mailing it, and a nominal charge for the laboratory work.

After three appli- cations of 4-X my lawn was completely free of weeds. As for SCUTL, I have never seen anything remove Crabgrass so completely as this product.

SCOTTS SOIL TESTING SERVICE The lead story carries suggestions as to when soil tests may be advisable. This may be in connection with a new lawn or plans to improve an old one. Samples of available topsoil, topdress- ing, humus, "black dirt" or other mate- rials may be checked before making a substantial investment. to illustrate Better criticism of soil from estab- lished lawns can be provided if a sam- ple of sod is submitted. This should be representative of growing conditions in the lawn. If these vary greatly it would be better to send as many samples as required the variations. Keep each sample separate, identified as to location. Proper Sampling Established Turf. Cut actual plugs of sod from the lawn, using a trowel or flat spade. Have them at least 4 inches square and 5 or 6 inches deep. Wrap firmly in waxed paper so section reaches laboratory as it was taken from the ground. Loose Materials. About a pint of soil is required. The sample should be rep- resentative of the whole. Take mate- rials from various locations and mix together to make a composite sample. Do not mix soils that are conspicuously different. Instead wrap and label each type separately. Containers. Coffee cans or any tin cans holding at least a pint with tight fitting lids make good containers for composite soil samples. Freezer canis- ters also make suitable shipping cartons but require outer wrapping for added protection. The use of glass jars and bottles is discouraged because of breakage. Sod and soil plugs require careful wrapping in substantial shipping car- tons made to fit the sample. Loosely packed sod samples arrive badly scram- bled making diagnosis of the sod and root condition difficult. Mailing Samples Advise by letter the number of sam- ples being sent, stating the lawn prob- lem or question. If soil is from an established lawn, describe past experi- ence in as much detail as possible. Do not place letter inside package as that would subject the entire shipment to first class postage.

SEED SITUATION In times like these, there is much talk about scare buying. People try to anticipate their future needs and buy ahead. It is difficult for a seed business to do that because of the problem of perishability. Seed scarcities usually result injury at harvest from time, drouth, crop late spring freezes, floods, plant dis- eases and, occasionally, to a short labor supply when the crop is ready for har- vest. Because grass seed comes from such a large geographical area, almost the entire world, the same factors sel- dom affect all varieties at once. Only a small percentage of any har- vest will make Scott quality. In two seasons in the early forties, there were times in late spring when there was not enough Scott quality seed to take care of all the demand. Frankly, no such emergency spring is hardly the time for although this bold statements. Airfields, army camps, defense plants, and aid to Europe can make quite a drain on seed supplies. is expected this In the early part of the year, Scott seed stocks are ample and the quality, thanks to constantly improved harvest- ing and processing techniques, was never so high. "Scotts" TRADE NAME Federal Judge McCarthy of the Bos- ton District Court permanently enjoined one Leslie N. Harvey of Leominister, Massachusetts, from illegal use of the trade name "Scotts" on grass seed and similar products. This was the outcome of a court action arising from the sale of an in- ferior blend of seed purported to be the genuine "Scotts Seed" long adver- tised and sold as a specific brand in Massachusetts and other New England states. The company is ever alert to prevent misuse of its trade-mark but it never learns about many such cases. There- fore, the buying public wishing Scotts Seed is urged to accept it in only the original sealed packages, and to make such purchases from known sources. W OE TO WEEDS! Is there anything more attractive and pleasurable than a smooth green carpet of grass, free from weeds? Well, hardly anything, especially now that it is so easy to keep out weeds. Last year Scotts introduced a new principle in a weed control product by chemically impregnating the active in- gredient into fine particles of vermicu- lite, a clean, dustfree, mica-like mate- rial. The new product, called S C U T L, worked wonders in taking out Crab- grass in two or three easy applications. Now this same principle is utilized in another product for control of broad- leaved weeds. The agronomist working with the chemist has succeeded in intro- ducing of 2,4-dichlorophenoxyacetic acid into the same type of carrier. The result is a dry applied control for the non-grass type of weeds. It is called 4-XD. alkanolamine salts the This is not the first broad-leaved weed control that could be used in the dry form. That precedent belongs to its than 4-XD. The L A WN CARE BOOKS the combination lawn food and weed control which has met with great suc- cess since introduction by Scotts several years ago.

In your issue No. 110, I take exception to the method of mowing the lawn outlined in your diagram. Early spring lawns are soft and the inside part of the uncut grass is naturally being bent during the operation of the mower. By mowing back and forth or reversing the cut, the mower has a tendency to pick up this bent-over grass. If the grass is heavy enough to need recutting, the clip- pings should probably be taken off. I am inclined to leave fine grass clippings on the lawn if I can. Salem, Oregon. D. H. CAMERON.
