quite inadequate. If you want the hcst 

 results and are willing to go to the 

 necessary expense, you should lay lines 

 of tiles every twenty feet lengthwise 

 or crosswise of the garden, accordirg 

 to how the slope is. These tiles should 

 not be less than three feet below the 

 surface and should have the necessary 

 slope. A depth of four feet would be 

 even better, for the deeper your drains, 

 the greater the depth of warmed, well- 

 aired and sweetened soil you will have 

 for the roots of your plants. If yon 

 reduce the depth, it will be impossible 

 for your plants to do so well, especially 

 in dry weather. 



Two-inch tiles will answer, and it is 

 better to connect these all in one main. 

 If 4-inch tiles are used for the main, 

 one of this size will carry five times as 

 much water as the 2-inch; a 5-inch 

 main will carry seven and one-half 

 times as much. Avoid all sharp curves. 

 While a fall of three to six inches in 

 100 feet will answer if the tiles are 

 carefully laid, twelve inches will be 

 better. One main outlet is better than 

 a large number, as it is easily marked 

 and kept free of obstructions. 



A good plan would be to lay seven 

 lines of 6-edged or 8-edged 2-inch tiles 

 lengthwise and let them enter a 4-inch 

 main. This would drain your garden 

 thoroughly; but do not lay the tiles 

 nearer the surface than three feet, and 

 a foot deeper will be still better. This 

 may seem like a big job at the outset, 

 but it will pay you in the long run. 

 A popular misconception is that water 

 runs down from above into drains. The 

 exact opposite is the case, as it is 

 forced up from below. 



The joints should be laid as closely 

 as possible, in order to keep out dirt, 

 [f the tiles are below the reach of frost, 

 damage is unlikely. Use tiles which 

 have been hard-burned. Round ones 

 will answer just as well as 6-sided or 

 8-8ided ones, if carefully laid. C. W. 



A NOVEL VIEW. 



Stamling at the center of the houses 

 of Plant B of the Poehlmann Bros. Co,, 

 Morton Grove, 111., one gets the view 

 shown in the accompanying illustration. 

 It probably is without parallel in the 

 greenhouse establishments of this coun- 

 try, for here the view is looking t'r-ough 

 fifty-three houses, each twenty-seven 

 feet wide, making a distance of l,4r,l 

 feet in a straight line, in addition to 

 which the walk goes on through boiler 

 sheds and alleyways another 197 feet, 

 considerably more than a quarter of a 

 mile. The car track is as straight as 

 though laid by railroad engineers and 

 is a great labor saver. Materials go in 

 that way, and cut blooms como out, 

 reducing the number of stejis to the 

 minimum and effecting an important 

 economy of time. One of tiie things 

 the Poehlmanns learned years ago is 

 that equipment is cheaper tlian labor, 

 that it costs money to have men w^alk 

 half a mile or so out of the houses and 

 in again, and that a reduction of the 

 muiiber of trips necessary and an in- 

 crease in the size of the loads carried 

 effected an important increase in the 

 time actually spent on the stock. The 

 larger the block of houses is, the larger 

 the proportion of time consumed going 

 in and out. The concrete walks and the 

 tracks and the cars have paid for them- 

 selves many times over. 



There is an interesting perspective 

 in this picture. The distance is so great

that the appearance is almost that of a 

 solid wall of asbestos covered j)ipes. 

 The big steam main overhead is Id-inch 

 pipe. Note the return by its side. In 

 each liouse tliere are four benches and 

 a 2 inch flow is taken oft' the main 

 for each bench, nuiking a total in the 

 picture of 424 pipes, 212 on a side, run 

 ning from tin' overhead main to the 

 header beneatli n bench. In addition 

 there are 84>> pipe supports for tie 

 wires. There arc three li^>-inch ])ipes 

 under each bench, or 1,272 in the fifty 

 three houses in this block. What a 

 showing it makes of business for tiif 

 ])ipe man! 



The asbestos covering of all the liow 

 pipes serves a double purpose: it con 

 serves heat, which is a saving, and it 

 keeps the center of the houses from lie 

 ing too warm, which in the aggrey.itc 

 adds considerably to the production m' 

 first quality stock.

Primula obconica now in 2'j inch 

 ]iots would be rather small for Christ 

 mas. but should flower moderately by 

 that date. Move them into a greenhous(> 

 kept at 48 to 50 degrees at night about 

 the end of September. Probably they 

 will need a larger sized pot to (lower in, 

 or they make up nicely in o-inch and 

 G-inch pans, if the same colors are 

 selected for each pan. C. W.

This is the conunon sweet basil,

 foliage of which is considerably used 

 for flavoring purposes. The shoots 

 should be cut while in flower, tied in 

 bunches and dried for winter use. The

FORMULA FOR THRIPS. 



»J. L. Washburn, of Passett iSf Wash 

 burn, Hinsdale, recently stated that he 

 had obtained frdin Weiidland i" Keiuud. 

 i:inihurst, HI., a formula fur the use 

 ipf brown sug;ir .uid Paris green that 

 \v;is woudirfully elfe(tiv(^ against 

 ihrips. The Review .-isked ;Mr. Keimel 

 lo give the whol<^ tradt' the benefit, and 

 he has coniplied as follows: 



''Our formula is: Take five pounds 

 of brown sugar to (uie pound of Paris 

 i^reen; mix diy; run through a fine 

 screen to take out lumjis. 



"To apply, take two ounces of the 

 niixtui'e to two gallons of water in 

 sprayer for 2nii f.i't of bi'iich; apply 

 this in tli(> afternoon late, or after 

 syringing, while the [)lants are still 

 wet, and if cle;ir llir next day svringe 

 olV to prr\-eiit the IcMves burning. 



"If used about once a wec^k this will 

 keep the plants clean, except possibl\- 

 in April and May, while lilacs and 

 snowballs are in bloom. During that 

 lime it could be used oftener, but never 

 :ipply a second time without syringing 

 th(> first ;ip]ilication off, or it will burn 

 the plants. Do not mix Iiin(> or an\ 

 (iiliiM- alkali with this, as it keeps the 

 thrips from eating the sugar ami kills 

 the elfect nf the poison."
