Show SHELTER FOR particularly desirable where edible material Is soa scarce roe de a I 1 g n 11 of two houses house given in baill bulletin issued by dopart mant Import importance ancO of protecting the milk cans can prepared by the united states department ot agriculture Aerl Acri culture tho the farmer who will build a 0 food shelter and furnish an abundance of et food in it will find that many birds of value to him as insect destroyers will haunt hla his premises this la is particularly cu true when there to la a scarcity of 0 bird food in the vicinity the united states department of agriculture in ill EL a recently published bulletin on bird houses bouses has offered designs tor for shelters that will protect food in nil all kinds of weather to induce birds to enter a food shelter baits are first placed ina in a 1 M 1 1 food shelter for attachment to post poat roof cut away to show construction sides made of glass size of panes 8 by 10 inches Inch je ous place outside and tho the birds are led by degrees to enter the inclosure such food as suet seeds or cracked nuts will prove attractive as bait two designs are given in tho the bulletin for adequate food shelters the first may be attached to a tree the other may be placed on top of a post poet or tree stub the sides aides are made of glass there Is no bottom to either of these structures besides protecting food such euch a shelter will provide a place where one interested te in birds can watch them conveniently it if the farmer has neither the time nor inclination to make a shelter but still desires to attract valuable birds by putting out food the next best thing Is to fasten the bait to trunks or bran branches chea of trees tressor sor or scatter it on the ground in sheltered places desirable birds may be attracted by other means than food particularly in summer on warm days they appreciate fresh water for drinking and bathing A shallow pool pook of varying depth it if only a toot foot across becomes a center of attraction for all the birds in the vicinity and it may be made with little effort and material only a small amount of cement la is required 0 or r it if that be lacking a paz pan with stones in it set in the ground will be equally serviceable cats cato are particularly dangerous to birds and should not be permitted food shelter for attachment to tru trunk k of tree near the homemade home made bird p pool dol during bathing hours or go near cear the food shelters designs for simple and elaborate bird houses that will interest all bird lovers are given in a farmers bulletin no which the united states dopart department part ment of agriculture has recently issued it Is entitled bird houses and how to build them and will be sent free of charge to anyone requesting it from the department protection for milk cans can much milk that seems to bo be perfectly good when it leaves the farm reaches the consumer in bad condition and the united states department of agriculture Is now convinced that this la Is frequently due to a rise la in tho aiu temperature of the milk during transportation por tation A series barlos ot of tests teats that h had 1 recently boon been completed shows chows th jhc thc importance of surrounding tho the milk cans during hot weather with some api ato insulating material which will effectually exclude the heat even when milk to IB to be shipped only a short distance its tempera temperature tur r Is should hould not ot be higher than 60 dogre degroote oti F at this temperature bacteria will wil multiply but tile the increase la is slow alow an and a few hours delay will result in 1 not noi serious injury in milk above 50 dei dam glees F Y the rate of bacteria growth 11 1 much more rapid it follows that who when tho the milk to la to bo be shipped a long din 11 tance it must bo be loaded on the cars aa a a temperature much lees than 60 50 d da means grees P F unless some efficient cul clent meana is IB taken to prevent the rising during tho the journey perhaps tho the most moat practical way 09 0 accomplishing this to la to wrap the cana can in a pair of quilt jackets wet burlap or some borna othor other similar material in th mhd course of the recent experiments mill w waa hauled a distance of 13 miles in id an average air temperature of do grews ardes I 1 P tho the milk being shipped at a temperature of 60 degrees F at tho end of three hours the cans calls that wore were hair quilt jacketed showed a raise of only 5 degrees IF those wrapped in wet burlap a ralso raise of 8 degroen degre eil iii milk in cans cane that were loft unprotected roso rose in the same time to a temperature pera ture of degrees fan an increase In creasa of degrees this Is much too high more afore elaborate methods of preserving milk during shipment by refrigeration are discussed in a professional bulletin just issued by the united states department of agriculture which deals in a technical way with many types of refrigerating appa apparatus r a tug the bulletin discusses fully the influence of time and temperature 0 on n bacteria in milk it also contains elaborate diagrams illustrating the different methods emple d in utilizing r refrigeration and cost of operating them this bulletin so long as the departments auprly lasts lasta will be sent free to all interested in the refrigeration of milk refrigeration however la is of course not always possible while any shipper can take the precaution of jacketing his milk cans cana |
