A Large Vegetable Growing Plant in Pennsylvania, Erected by King Construction Co. 



Note that heatinp pipca are sufficiently high to permit the ground being plowed and cultivated with a horse. The large door at the end of each Iiouhc will allow a Uani 



and waggon to enter with manure, al.so machinery for cultivating and for other purposes.

the difficulty of getting at the glass for 

 repairs. Nevertheless, a house 150 feet 

 iwide by 500 feet long has been built ana 

 IS claimed to be a commercial success, 

 he popular question at present as to 

 ize of house for a man to start with, 

 allow for extension as his business 

 grows, seems to hinge around connected 

 houses of twenty-one feet, eight and a 

 half inches, using twelve foot sash bars, 

 lumber length, and twenty-five feet, twd 

 and a quarter inch, using fourteen foot 

 bars, or, where land is sufficiently plenti- 

 ful, separate houses of not less than forty 

 to sixty feet in width. 



In the connected houses, continuous 

 single ventilation is usually installed but 

 if extra ventilation is required, then ven- 

 ilation each side of ridge can be used 

 nd the King construction ventilator is 

 such that the extra side can be added aft- 

 rwards if required, using the same 

 lass that was in the roof without cut- 

 ting. 



In these houses, also, the lightest sash 

 bar, No. 6, can be used in the roof. Ow- 

 ing to the extra light-admitting qualities 

 of this bar, the advantage gained by its 

 use will out-weigh many objections that 

 can be raised against it. The number of 

 valley gutters required gives easy access 

 to the roof for repairs and when of iron, 

 as they should be, present sufficient sur- 

 face for drainage and the melting of 

 snow with reasonable rapidity. The nar< 



rower span, twenty-one feet, eight and a 

 half inches, is recommended where weath- 

 er conditions are the more severe. Oth- 

 erwise, the standard twenty-five feet 

 spans have met with much success and 

 are cheaper to install. 



For the separate houses averaging fif- 

 ty feet span, ventilation both sides of the 

 ridge should be used since as regards 

 amount, this is only equal to single ven- 

 tilation in the block previously referred 

 to. If more ventilation is required, 

 however, side ventilation can be resorted 

 to. It is held by growers, however, that 

 side ventilation in wide houses, being 

 only local, is a poor substitute for proper 

 or sufficient ventilation at ridge. 



In resorting to side ventilation in order 

 to create a current of air (which, how- 

 ever, is looked upon by some as of the 

 nature of a draft and injurious in many 

 cases), as Mr. Fraser remarks, the open- 

 ing should be low down, thus drawing 

 the coolest air into the house. In work- 

 ing with the growers in the Great Tron- 

 dequoit vegetable growing district of 

 the United States, a cut of one of whose 

 houses is here shown, the King Con- 

 struction Co. has met some of the de- 

 mands for side ventilation, by the plans 

 shown in Figs, i and 2, which we ex- 

 plain as follows : The glass in the side 

 of a vegetable house should reach within 

 one foot of the ground, where weather 

 conditions will admit, but in this country 



where snow is plentiful and liable to bank 

 up against the walls, two feet or in an 

 extra wide house, even more dead wall 

 may be necessary. 



In some cases, in the district referred 

 to, an opening is left under the framing 

 of the sash (See Fig. i) which is banked 

 up in the winter. In other cases, side 

 sashes are hinged to the eve, or where 

 eves are too high, a header is run along 

 the side of the house as in Fig. 2, to 

 which the sash is hinged.

About Tomatoes 



The illustration on our front cover 

 represents the tomato patch of Mr. Jas. 

 A. Woods, of Stratford, Ont. The var- 

 iety staked is Livingstone's Globe and 

 the others, Livingstone's Favorite. The 

 photograph was taken two years ago on 

 August 2nd. According to Mr. Wood, 

 the ErIiana and varieties of that type 

 are not successful in his locality, either 

 in crop or quality. 



When writing of the location, Mr. 

 Wood said: "The elevation here is about 

 1,200 feet above sea level, or say 950 

 feet above Lake Ontario. The June 

 frost is our chief dread. Scientifically, it 

 may have nothing to do with it, but prac- 

 tically this frost is co-incident with the 

 full moon."
